Without one the job fails instead of returning <code>400</code>. <code>daily</code> boolean <code>false</code> Treat the title as daily/date-based content and fill missing episode air dates from TVDB. The fill needs <code>enrich</code> and a TVDB ID. An air date the service already set is kept. <code>output_dir</code> string <code>null</code> Output directory, relative to the server's downloads directory.

A client that reports no region is not blocked. The   proxy must be a full proxy URI unless the operator gives your API key   <code>server_proxy</code>. Without <code>server_proxy</code> the server does not resolve country   codes with its own proxy providers, and it rejects the remote session when   it sits in a different region from the reported one, asking the client to   pass <code>--proxy</code> with its own proxy, or <code>--no-proxy</code> to accept the server's   own connection. With <code>server_proxy</code> the server picks a proxy that matches   the client region itself. For <code>--proxy controld:ca</code> the client points its   Control D profile at the region and sends only the resolver, as   <code>controld://&lt;resolver&gt;@dns.controld.com</code>. The server counts it as a full proxy   URI and runs its own forwarder for it. A bare region skips Control D, because its   proxy is a forwarder on the client. See   Control D</li> <li>Track-selection hints (<code>range_</code>, <code>vcodec</code>, <code>quality</code>, <code>best_available</code>) so   the server fetches the right manifests</li> <li>Your language and audio codec selection (<code>-l</code>, <code>-vl</code>, <code>-al</code>, <code>-a</code>, <code>-fs</code>)   in a <code>dl_params</code> object. Some services fetch one manifest   for each audio language, and pick the languages from these values</li> <li>Your local per-service cache files (e.g. refreshed tokens), including   files in subdirectories of the service cache directory, but only the files   for the active profile. The client withholds a file whose path, in any   directory or file name, embeds a hash of another credential or the name of   another profile. One profile's tokens   therefore never reach the server while you use a different profile. At   worst, a withheld file makes the server authenticate again</li> </ul> <p>The server uses its own accounts only when the operator lists the service in <code>serve.server_accounts</code> and gives your API key <code>server_accounts</code> in <code>serve.users</code>. For any other service, a client that sends no credentials or cookies authenticates with nothing. For a listed service the client sends no credentials, cookies, or cache at all: the server picks one of its own accounts that works in your region and rotates through them. <code>--proxy ca</code> picks a <code>ca</code> account.</p> <p><code>GET /api/services</code> advertises the regions those accounts cover. When your own region is not one of them and you set no <code>--proxy</code>, the client resolves a proxy for the first advertised region itself, so both sides sit in a region the account works in. This is a bare region query, so it skips Control D. A server-account service does not accept a <code>controld://</code> resolver from the client.</p> <p>The server responds immediately with a session ID and a status. Authentication runs in the background on the server.</p> <p>Some services need a one-time code, PIN, or device confirmation. When the server's auth flow asks for input, the remote session enters <code>pending_input</code>. The client polls, displays the prompt to you locally, collects your answer, and sends it back. The server's auth thread resumes with your response.</p> <pre><code>Enter the 6-digit code sent to your email: 483920\n</code></pre> <p>A client older than the <code>service_params</code> change sends service options as flat body keys only. A flat key that shares a name with a transport field (such as <code>profile</code>, which at the top level always means the credentials profile) no longer reaches the service; the server logs a warning naming the dropped key. Update the client to send service options under <code>service_params</code>.</p> <p>The server also mirrors the service's own log output (<code>self.log</code>) into a per-session buffer. The client drains it through <code>GET /api/session/{id}/logs</code> after each step and prints the records locally, so you see the server-side reason when a step fails.</p> <p>Once authenticated, the client fetches the title list, then the tracks for the chosen title. The tracks come back with playback URLs, and the server ships DASH/ISM manifests as compressed XML so the client can re-parse them locally for downloading. A service can build an AdaptationSet of its own that the served manifest does not contain. Each such track gets a one-AdaptationSet MPD in <code>track_manifests</code>, and the client re-parses that instead. Any <code>session_headers</code> / <code>session_cookies</code> the server used are merged into the client's local HTTP session.</p> <p>The tracks response repeats the title. A service can rewrite title fields inside <code>get_tracks</code>, so the client takes this copy in place of the one from the title list. Each track carries the full local field set. After the manifest re-parse the client overlays the JSON-safe part of the service-set <code>track.data</code>, so a service value wins over the parser's. An attachment that the service wrote to a file on the server travels as base64, and the client writes it to its own temp directory.</p> <p>For a DRM-protected title the client either proxies its CDM challenge through the server, or, if <code>server_cdm: true</code>, asks the server to do the full CDM flow and return the content keys directly. See Server-side vs. proxied CDM below.</p> <p>The client downloads, decrypts, and muxes locally. While it works, it sends a keep-alive request to the remote session at an interval of one third of <code>session_ttl</code>, so a long download does not let the remote session expire. On completion, and also when <code>dl</code> exits early (<code>--list</code>, Ctrl+C, an error), it deletes the remote session. If the login belongs to the client, the <code>DELETE</code> request returns the updated cache files (for example a refreshed token) and the client saves them locally, so the next remote session can skip interactive authentication. The login belongs to the client when the client sent cookies, credentials, or cache files, or answered a login prompt (a device code or an OTP) that led to a successful login. A server-account login never does, and neither does a remote session on the server's device (see below). The client saves only the returned files that pass the same profile check it applies before it sends them, so a file for another profile cannot overwrite that profile's local file.</p> <p>Renaming remote titles locally</p> <p>You can rename titles for a remote service you do not have installed locally by adding a <code>title_map</code> under that service in your client <code>remote_services.&lt;name&gt;.services</code> config. The server sends raw titles. Your local map wins.</p> <p>This is deliberate: the server does no <code>title_map</code> remapping of its own and sends titles exactly as the service returns them. All remapping happens on the client, applied to the titles the server sends back. It keeps the final output name fully under the client's control and lets you rename titles even for services you have no local install of.</p>"},{"location":"dev/rest-api/remote-sessions/#server-side-vs-proxied-cdm","title":"Server-side vs. proxied CDM","text":"<p>There are two ways DRM keys get resolved, chosen by the client's <code>server_cdm</code> flag.</p> Proxied CDM (default)Server-side CDM (server_cdm: true) <p>Your local CDM builds the license challenge.

The decrypters accept a wrong content key and write noise. unshackle therefore trusts a content key from a vault only after FFmpeg decodes the decrypted track with strict error detection. For a fragmented MP4, unshackle reads from the encrypted file which fragments each KID encrypts, and FFmpeg decodes up to three windows of each KID: from its first, middle and last fragment on through the next fragments of that KID, for up to 4 seconds. A window never runs into a fragment of another KID or a clear fragment. A clear lead or a lead under another KID therefore cannot hide a wrong content key, and only the KID that fails is flagged. A KID that is not in this map, and every KID of any other file, gets one check of the whole file. FFmpeg decodes the first seconds and the last seconds. A failure there flags each of those KIDs. When a mapped KID fails, the KIDs that are not in the map get no verdict from that pass; the retry with the replaced key judges them. Content keys from a licence skip this check.

It requires at least <code>SELECT</code> to load at all (a missing <code>SELECT</code> grant makes the vault fail to load). Writing keys additionally needs <code>INSERT</code>, and creating a new service table needs <code>CREATE</code>. A read-only account still works fine as a lookup source. It cannot push new keys.

If you can see important audio/sound transcriptions and not only dialogue   and it does not have the indicators of CC, then it is most likely SDH.  If it does not have important audio/sounds transcriptions it might only be   regular subtitling (you would not mark as CC or SDH). This would be the   case for most translation subtitles.

Unknown names are ignored with a warning. Leave it unset for the default order:</p> <pre><code>metadata_providers: [imdb, omdb, simkl, tmdb, tvdb, anilist]\n</code></pre> <p>Whatever the order, unshackle skips a metadata provider that has no API key. <code>imdb</code> and <code>anilist</code> need no API key, so they are always available. Available names are <code>imdb</code>, <code>omdb</code>, <code>simkl</code>, <code>tmdb</code>, <code>tvdb</code>, and <code>anilist</code>. The old name <code>imdbapi</code> still works and is read as <code>imdb</code>.</p> <p><code>anilist</code> is last in the default order. It only answers for anime and returns nothing for anything else, so it is harmless there. Move it earlier if you mostly download anime.</p> <p>The order applies to a title search and to a direct lookup of an ID you give with <code>--tmdb</code>, <code>--imdb</code>, <code>--tvdb</code>, or <code>--anilist</code>. A supplied ID always goes to the providers that read that kind of ID, and it never falls back to a title search.</p> <p>Which AniList title <code>anilist_title_language</code> picks</p> <p>AniList holds up to three titles for a work: the English one, the romaji transliteration, and the native one. This option says which of them unshackle uses:</p> <pre><code>anilist_title_language: romaji\n</code></pre> <p>A work does not always have all three. When the one you asked for is unset on AniList's side, unshackle falls back in the order english \u2192 romaji \u2192 native.

The title search is dead, and that includes the keyless <code>imdb</code> metadata provider. Titles, years and languages then come only from the service.</p> <pre><code>disable_metadata: true\n</code></pre> <p>An ID you give with <code>--tmdb</code>, <code>--imdb</code>, <code>--tvdb</code>, or <code>--anilist</code> is your permission to use that ID. That lookup still works. unshackle looks the ID up directly, cross references the other IDs from it, and <code>--enrich</code> still reads that source. unshackle stops only the lookups you did not ask for.</p> <p>The <code>imdb</code> provider needs no key</p> <p>It replaces the earlier <code>imdbapi</code> metadata provider, which read a third-party mirror (api.tiffara.com) and needed the <code>imdb_api_enabled</code> switch. That option is gone: delete it from your config, where it is now ignored.</p> <p>A different order per title kind</p> <p>Give a map instead of one list when the best source differs by kind. TVDB is strongest on series, TMDB on films. There are two kinds, <code>tv</code> and <code>movie</code>, and this example sets both of them and names every metadata provider, so nothing is left to the default:</p> <pre><code>metadata_providers:\n  tv: [tvdb, tmdb, simkl, imdb, omdb]\n  movie: [tmdb, imdb, omdb, simkl, tvdb]\n</code></pre> <p>Each list is independent: it both orders and filters that kind on its own, so unshackle still uses for <code>movie</code> a metadata provider you leave out of <code>tv</code>. Here unshackle tries TVDB first for a series and last for a film.</p> <p>You do not need to give both keys, or a full list in each. A kind you leave out uses the default order:</p> <pre><code>metadata_providers:\n  tv: [tvdb, tmdb]     # movies keep the default order\n</code></pre> <p><code>tv</code> covers every episode and <code>movie</code> covers every film. unshackle only looks up metadata for those two kinds, so unshackle ignores any other config key, such as <code>anime</code> or <code>music</code>.</p> <p><code>ipinfo_api_key</code> never touches your service sessions</p> <p>unshackle sends the token only to <code>api.ipinfo.io</code>, as a per-request <code>Authorization</code> header. It never goes on your service HTTP session, so it cannot leak to a streaming service.

It also means a path containing spaces always arrives as a single argument on every OS.</p> <p>Prefix your variables</p> <p>Titles, episode names and IDs come from the streaming service, not from you. Tokenizing first stops a value becoming a new argument, but a value on its own can still be a whole argument. A bare <code>{title}</code> whose value is <code>--upload-file=/etc/passwd</code> would arrive as an option to your script, not as text. Write <code>--title={title}</code>, not a bare <code>{title}</code>, so a service can never forge a flag. unshackle refuses to operate a command when a substituted value would become an option-like token (one that starts with <code>-</code>), and logs a warning instead.</p> <p>No shell features, and name your interpreter</p> <p>Pipes, <code>&amp;&amp;</code>, <code>&gt;</code> redirection, <code>~</code> and globs do not work, because unshackle uses no shell.

Omit to allow all. <code>remote_only</code> bool <code>false</code> Expose only the remote service session endpoints (health, services, search, session) and disable the rest of the REST API. <code>dashboard</code> dict (unset) Developer dashboard: <code>key</code> is the API key for the read-only <code>/api/dashboard/</code> endpoints (status, remote sessions, remote session logs, jobs, keys, services, health, logs, SSE events). Unset leaves those routes unregistered. See dashboard endpoints. <code>session_ttl</code> int (s) <code>300</code> Seconds a remote session can stay idle before it expires. A remote client sends keep-alive requests to its remote session during a download, so the remote session does not expire during a long download. <code>max_sessions</code> int or null <code>100</code> Maximum concurrent remote sessions; at the cap the server evicts the oldest. Set it to <code>null</code> or <code>0</code> for no limit, which is also what <code>/api/dashboard/status</code> then reports, so a dashboard can tell \"no cap\" from a cap that happens to sit at the default. <code>history_limit</code> int <code>100</code> How many finished jobs to retain in history. <code>compression_level</code> int <code>1</code> gzip level for responses. <code>services_refresh_interval</code> int (s) <code>0</code> How often the server pulls the git-backed service repositories in <code>directories.services</code> and hot-reloads the services that changed. <code>0</code> turns it off. A service with a running or queued job, or a live remote session, is staged and swaps to the new code as soon as its last job and session finish. <code>services_staged_max_age</code> int (s) <code>0</code> How long a staged service waits for its jobs and sessions before the server swaps it in anyway. <code>0</code> waits forever. Set it on a server whose popular services never have a quiet moment. A session that is live at the swap keeps the old code until it ends; a running job keeps its old code too. <code>global_speed_limit</code> str (unlimited) Server-wide download speed cap, e.g. <code>10M</code>, <code>1.5G</code> or plain bytes/sec (same format as <code>speed_limit</code>). One shared budget across all concurrent jobs; the server ignores per-job speed limits while it is set. <code>cdm_overrides</code> list or bool (unset) Allowed per-request CDM overrides: a list of permitted device names, or <code>true</code> for any. Unset rejects every override. <code>allow_job_credentials</code> bool <code>false</code> Permit clients to supply credentials per job. <code>server_accounts</code> dict <code>{}</code> Services whose remote sessions use the server's own <code>credentials</code> and cookie files instead of the client's (see below). <code>devices</code> list (auto) Widevine devices offered; auto-filled from <code>directories.wvds</code>. <code>playready_devices</code> list (auto) PlayReady devices; auto-filled from <code>directories.prds</code>. <p>Each entry under <code>users</code> uses that user's API key as its name, and can set its own <code>services</code>, <code>devices</code>, and <code>playready_devices</code> allowlists, narrowing the global ones, plus an optional <code>username</code> used as the log label for that API key (defaults to a truncated form of the API key). A user with no <code>playready_devices</code> config key gets no PlayReady access at all, not the global list.</p> <p><code>server_cdm</code> decides whether the server runs the CDM licensing for that API key. Set it to <code>true</code> to enable every service, or to a list of service tags to enable only those. It is <code>false</code> unless the entry sets it. For a service the API key does not cover, the server tells a remote client configured with <code>server_cdm: true</code> to license with its own local CDM instead, and a client that asks anyway gets a <code>FORBIDDEN</code> error. Because a download job always licenses with the server's CDM, an API key without <code>server_cdm</code> for that service also cannot submit or retry <code>/api/download</code> jobs. Keys that have no <code>users</code> entry, such as <code>api_secret</code>, keep server CDM access.</p> <p><code>server_cdm_max_height</code> limits the live licences the server's device makes for that API key. Set it to a height in pixels for every service, or to a map of service tag to height with an optional <code>default</code> entry. A service the map does not name or sets to <code>null</code> gets the <code>default</code>, and with no <code>default</code> it has no limit. The server compares the limit with the lowest <code>-q</code> that selects the track: the track height, or the 16:9 height from the width when that is lower. The server reads the remote client's <code>-q</code> when the remote session starts:</p> <ul> <li>With no <code>-q</code>, or a <code>-q</code> at or below the limit, the server CDM licenses the remote session. The server   refuses a live licence for a video track taller than the limit, and the client licenses that   track with its own local CDM.</li> <li>With a <code>-q</code> above the limit, the client's own local CDM licenses every track of the remote session.   The service sees the DRM system and security level of the client's device. A client with no   local CDM gets a <code>SERVER_CDM_CAPPED</code> error.</li> <li>A download job must pass a <code>quality</code> at or below the limit, and must not set <code>best_available</code> or   a <code>HYBRID</code> range. <code>HYBRID</code> always keeps the lowest Dolby Vision track, at any quality. A job with   no <code>quality</code>, with a higher one, with <code>best_available</code>, or with <code>HYBRID</code> gets a <code>SERVER_CDM_CAPPED</code>   error. The server checks the values the job runs with, after it applies the service defaults   and the <code>serve:</code> download defaults.</li> </ul> <p>The limit protects the server's device, not the content keys. For a Widevine track, a server vault still supplies a content key at every height. A PlayReady track never reads the vault, so above the limit it always goes to the client's device. A licence for a lower track can carry the content key of a higher track when the service shares one content key between them. With server accounts enabled, a client that reports a stronger device than it holds makes the server's account request those manifests; the licence server still refuses its challenge.</p> <p><code>server_vault</code> lets a remote session that the client's own device licenses take content keys from the server vault. Set it to <code>true</code> for every service, or to a list of service tags. It is <code>false</code> unless the entry sets it, and <code>server_cdm</code> for a service implies it. The server looks up every KID of the track in its vault and makes no live licence. A track that the vault does not hold goes back to the client's device. When the service runs the remote session on the server's own device (a service option, such as a server-identity flag), the client's own vaults, and the server vault with this grant, are the only source, and a missing content key stops the download.</p> <p><code>admin</code> is a boolean that lets the API key run the maintenance endpoints (clear-cache, clear-temp, refresh-services). It is <code>false</code> unless the entry sets it. Keys that have no <code>users</code> entry, such as <code>api_secret</code>, keep that access.</p> <p>A <code>tier</code> names an entry under <code>serve.tiers</code>, which holds the settings that several API keys share. Today a tier carries <code>rate_limit</code>, the requests per hour that API key may make; an API key can also set its own <code>rate_limit</code>, which wins over its tier's. An API key with neither has no limit. Going over the limit answers <code>429</code> with a <code>Retry-After</code> header. The server keeps a fixed window rather than a sliding one: it opens on the first request and resets an hour later. A <code>tier</code> that names no entry under <code>serve.tiers</code>, or a <code>rate_limit</code> that is not a positive whole number, stops the server at startup, because the alternative is an API key that silently gets no limit. The rate limit never applies to the dashboard key, and never to <code>/api/health</code>.</p> <p><code>server_accounts</code> lists, per service, the accounts the server lends to remote sessions. A remote session for a listed service ignores the credentials, cookies, and cache the client sends and uses one of the server's own profiles from <code>credentials</code>. For a service that is not listed the server never uses its own accounts: a client that sends nothing authenticates with nothing.</p> <pre><code>credentials:\n  EXAMPLE1:\n    ca_main: user1@example.com:pw1\n    eu_box: user2@example.com:pw2\n    shared: user3@example.com:pw3\n\nserve:\n  server_accounts:\n    EXAMPLE1:\n      ca_main: ca             # one country\n      eu_box: [gb, fr, de]    # a list of countries\n      shared: global          # any region\n    EXAMPLE2: true            # every profile (or the single credential), any region\n</code></pre> <p>Each entry under a service names a profile from <code>credentials</code>, or a cookie file <code>cookies/&lt;TAG&gt;/&lt;profile&gt;.txt</code> for a service that has no credentials. Its value is the region or regions that account works in: a two-letter country code, a list of them, or <code>global</code>. Quote <code>no</code> (Norway), because YAML reads the bare word as <code>false</code>.</p> <p>The region of a remote session is the country the client asked for with <code>--proxy</code> (<code>ca</code>, <code>ca1</code>, <code>provider:ca</code>), the server's own region with <code>--no-proxy</code>, or the client's own region otherwise. A full proxy URI carries no country, so with one only a <code>global</code> account matches. The server picks the profiles that cover that region (or are <code>global</code>) and rotates through them round-robin, one account per remote session. With no matching account it rejects the remote session. These services ignore the client's <code>-p/--profile</code>.</p> <p>Cookies come only from the profile's own file (<code>cookies/EXAMPLE1/ca_main.txt</code>; the server does not read a bare <code>cookies/EXAMPLE1.txt</code>), and each account keeps its own persistent cache under <code>cache/_accounts/EXAMPLE1/&lt;profile&gt;/</code>, so refreshed tokens survive the remote session but never cross accounts. <code>serve</code> refuses to start when a listed profile has neither an entry under <code>credentials</code> nor a cookie file. <code>/api/search</code>, <code>/api/list-titles</code> and <code>/api/list-tracks</code> use the same pool, matched on the client's reported region, and return <code>FORBIDDEN</code> to an API key without the opt-in. Rotation is per process and does not track which accounts are in use, so concurrent remote sessions can share one account.</p> <p>A <code>users</code> entry opts in to those accounts with <code>server_accounts: true</code> (every listed service) or a list of service tags. It is off unless set: an API key without it authenticates with the credentials the client sends, as for any other service, and <code>/api/services</code> does not advertise the server's accounts to it. API keys with no <code>users</code> entry, such as <code>api_secret</code>, keep access.</p> <p><code>server_proxy</code> decides whether that API key may use the proxy providers the server has configured. There is no implicit access: only the boolean <code>true</code> on the API key's <code>users</code> entry grants it, and an API key without a <code>users</code> entry has no access either. Without the opt-in the server never spends its own proxy subscriptions on a remote client: not to resolve a country code in <code>proxy</code>, not to match the client's region, and not for a service geofence. This applies to remote sessions, search, title lists, and <code>/api/download</code> jobs alike. Such a client must send a full proxy URI, or <code>no_proxy</code> to accept the server's own connection. Set <code>server_proxy: true</code> to let that API key send a country code or a <code>provider:country</code> value, and to let the server pick a proxy for the client's region and for a service geofence. The client reports its own region; a client that reports none is not blocked.</p> <pre><code>serve:\n  api_secret: change-me\n  remote_only: true\n  services: [EXAMPLE1, EXAMPLE2]\n  services_refresh_interval: 3600   # pull the service repositories hourly and reload what changed\n  # server-wide download defaults (same keys as the `dl:` block)\n  downloads: 3\n  best_available: true\n  tiers:\n    bot: { rate_limit: 600 }      # requests per hour, for every key on this tier\n  users:\n    a1b2c3d4:                     # this user's API key\n      services: [EXAMPLE1]        # may only use EXAMPLE1\n      tier: bot                   # 600 requests/hour; 429 with Retry-After once over\n    e5f6a7b8:\n      server_cdm: true            # this key may have the server do the licensing\n      server_cdm_max_height: 1080 # above 1080p the client licenses with its own device\n    c9d0e1f2:\n      services: [EXAMPLE1, EXAMPLE2]\n      server_cdm: [EXAMPLE1]      # the server licenses only EXAMPLE1; EXAMPLE2 needs a local CDM\n      server_accounts: [EXAMPLE1] # may authenticate EXAMPLE1 with one of the server's own accounts\n      server_proxy: true          # this key may also use the server's proxy providers\n    f3a4b5c6:\n      services: [EXAMPLE1]\n      server_vault: [EXAMPLE1]    # the client's device licenses; the server vault still serves keys\n</code></pre> <p><code>dl</code> keys inside <code>serve</code></p> <p>Most <code>dl</code> flag keys (<code>downloads</code>, <code>workers</code>, <code>best_available</code>, and so on) can be set directly inside <code>serve</code>, where they apply to every request the server handles.

An ID whose provider is unconfigured, such as <code>tmdb_id</code> with no <code>tmdb_api_key</code>, fails the job rather than returning <code>400</code>. <code>anilist_id</code> needs no API key. <code>tvdb_order</code> <code>official</code>, <code>dvd</code>, <code>absolute</code>, <code>alternate</code>, <code>regional</code> <code>null</code> Renumber episodes to a TVDB season order. Falls back to the <code>tvdb_order</code> config option. <code>enrich</code> boolean <code>false</code> Overwrite title, year and original language with the external source's.

Without one the job fails instead of returning <code>400</code>. <code>daily</code> boolean <code>false</code> Treat the title as daily/date-based content and fill missing episode air dates from TVDB. The fill needs <code>enrich</code> and a TVDB ID. An air date the service already set is kept. <code>output_dir</code> string <code>null</code> Output directory, relative to the server's downloads directory.

A client that reports no region is not blocked. The   proxy must be a full proxy URI unless the operator gives your API key   <code>server_proxy</code>. Without <code>server_proxy</code> the server does not resolve country   codes with its own proxy providers, and it rejects the remote session when   it sits in a different region from the reported one, asking the client to   pass <code>--proxy</code> with its own proxy, or <code>--no-proxy</code> to accept the server's   own connection. With <code>server_proxy</code> the server picks a proxy that matches   the client region itself. For <code>--proxy controld:ca</code> the client points its   Control D profile at the region and sends only the resolver, as   <code>controld://&lt;resolver&gt;@dns.controld.com</code>. The server counts it as a full proxy   URI and runs its own forwarder for it. A bare region skips Control D, because its   proxy is a forwarder on the client. See   Control D</li> <li>Track-selection hints (<code>range_</code>, <code>vcodec</code>, <code>quality</code>, <code>best_available</code>) so   the server fetches the right manifests</li> <li>Your language and audio codec selection (<code>-l</code>, <code>-vl</code>, <code>-al</code>, <code>-a</code>, <code>-fs</code>)   in a <code>dl_params</code> object. Some services fetch one manifest   for each audio language, and pick the languages from these values</li> <li>Your local per-service cache files (e.g. refreshed tokens), including   files in subdirectories of the service cache directory, but only the files   for the active profile. The client withholds a file whose path, in any   directory or file name, embeds a hash of another credential or the name of   another profile. One profile's tokens   therefore never reach the server while you use a different profile. At   worst, a withheld file makes the server authenticate again</li> </ul> <p>The server uses its own accounts only when the operator lists the service in <code>serve.server_accounts</code> and gives your API key <code>server_accounts</code> in <code>serve.users</code>. For any other service, a client that sends no credentials or cookies authenticates with nothing. For a listed service the client sends no credentials, cookies, or cache at all: the server picks one of its own accounts that works in your region and rotates through them. <code>--proxy ca</code> picks a <code>ca</code> account.</p> <p><code>GET /api/services</code> advertises the regions those accounts cover. When your own region is not one of them and you set no <code>--proxy</code>, the client resolves a proxy for the first advertised region itself, so both sides sit in a region the account works in. This is a bare region query, so it skips Control D. A server-account service does not accept a <code>controld://</code> resolver from the client.</p> <p>The server responds immediately with a session ID and a status. Authentication runs in the background on the server.</p> <p>Some services need a one-time code, PIN, or device confirmation. When the server's auth flow asks for input, the remote session enters <code>pending_input</code>. The client polls, displays the prompt to you locally, collects your answer, and sends it back. The server's auth thread resumes with your response.</p> <pre><code>Enter the 6-digit code sent to your email: 483920\n</code></pre> <p>A client older than the <code>service_params</code> change sends service options as flat body keys only. A flat key that shares a name with a transport field (such as <code>profile</code>, which at the top level always means the credentials profile) no longer reaches the service; the server logs a warning naming the dropped key. Update the client to send service options under <code>service_params</code>.</p> <p>The server also mirrors the service's own log output (<code>self.log</code>) into a per-session buffer. The client drains it through <code>GET /api/session/{id}/logs</code> after each step and prints the records locally, so you see the server-side reason when a step fails.</p> <p>Once authenticated, the client fetches the title list, then the tracks for the chosen title. The tracks come back with playback URLs, and the server ships DASH/ISM manifests as compressed XML so the client can re-parse them locally for downloading. A service can build an AdaptationSet of its own that the served manifest does not contain. Each such track gets a one-AdaptationSet MPD in <code>track_manifests</code>, and the client re-parses that instead. Any <code>session_headers</code> / <code>session_cookies</code> the server used are merged into the client's local HTTP session.</p> <p>The tracks response repeats the title. A service can rewrite title fields inside <code>get_tracks</code>, so the client takes this copy in place of the one from the title list. Each track carries the full local field set. After the manifest re-parse the client overlays the JSON-safe part of the service-set <code>track.data</code>, so a service value wins over the parser's. An attachment that the service wrote to a file on the server travels as base64, and the client writes it to its own temp directory.</p> <p>For a DRM-protected title the client either proxies its CDM challenge through the server, or, if <code>server_cdm: true</code>, asks the server to do the full CDM flow and return the content keys directly. See Server-side vs. proxied CDM below.</p> <p>The client downloads, decrypts, and muxes locally. While it works, it sends a keep-alive request to the remote session at an interval of one third of <code>session_ttl</code>, so a long download does not let the remote session expire. On completion, and also when <code>dl</code> exits early (<code>--list</code>, Ctrl+C, an error), it deletes the remote session. If the login belongs to the client, the <code>DELETE</code> request returns the updated cache files (for example a refreshed token) and the client saves them locally, so the next remote session can skip interactive authentication. The login belongs to the client when the client sent cookies, credentials, or cache files, or answered a login prompt (a device code or an OTP) that led to a successful login. A server-account login never does, and neither does a remote session on the server's device (see below). The client saves only the returned files that pass the same profile check it applies before it sends them, so a file for another profile cannot overwrite that profile's local file.</p> <p>Renaming remote titles locally</p> <p>You can rename titles for a remote service you do not have installed locally by adding a <code>title_map</code> under that service in your client <code>remote_services.&lt;name&gt;.services</code> config. The server sends raw titles. Your local map wins.</p> <p>This is deliberate: the server does no <code>title_map</code> remapping of its own and sends titles exactly as the service returns them. All remapping happens on the client, applied to the titles the server sends back. It keeps the final output name fully under the client's control and lets you rename titles even for services you have no local install of.</p>"},{"location":"dev/rest-api/remote-sessions/#server-side-vs-proxied-cdm","title":"Server-side vs. proxied CDM","text":"<p>There are two ways DRM keys get resolved, chosen by the client's <code>server_cdm</code> flag.</p> Proxied CDM (default)Server-side CDM (server_cdm: true) <p>Your local CDM builds the license challenge.

The client sends only those keys, from its own <code>services: &lt;TAG&gt;:</code>   block in <code>unshackle.yaml</code>.

The create response sets <code>server_device</code> to <code>true</code> for such a remote session. The service then uses the server's own config: the client's identity values do not apply. The client reads the server vault only when the API key has the <code>server_vault</code> grant (or <code>server_cdm</code>); without it, the client reads only its own vaults.

Anime is the usual beneficiary, but nothing here applies only to anime. This only adds the <code>{absolute}</code> naming variable. <code>--enrich</code> never changes the season and episode numbers.</p> <p>With <code>--daily</code>, <code>--enrich</code> also fills in the air date of each episode from TVDB.

The decrypters accept a wrong content key and write noise. unshackle therefore trusts a content key from a vault only after FFmpeg decodes the decrypted track with strict error detection.

A window never runs into a fragment of another KID or a clear fragment. A clear lead or a lead under another KID therefore cannot hide a wrong content key, and only the KID that fails is flagged. A KID that is not in this map, and every KID of any other file, gets one check of the whole file. FFmpeg decodes the first seconds and the last seconds. A failure there flags each of those KIDs. When a mapped KID fails, the KIDs that are not in the map get no verdict from that pass; the retry with the replaced key judges them. Content keys from a licence skip this check.

A kind you leave out uses the default order:</p> <pre><code>metadata_providers:\n  tv: [tvdb, tmdb]     # movies keep the default order\n</code></pre> <p><code>tv</code> covers every episode and <code>movie</code> covers every film. unshackle only looks up metadata for those two kinds, so unshackle ignores any other config key, such as <code>anime</code> or <code>music</code>.</p> <p><code>ipinfo_api_key</code> never touches your service sessions</p> <p>unshackle sends the token only to <code>api.ipinfo.io</code>, as a per-request <code>Authorization</code> header.

Remove the entry to use the server CDM for that service. The <code>default</code> entry does not count.</p> <p>The server has the last word. When it keeps the server CDM for a remote session that your device was to license, unshackle shows a warning.

It sends the first name. If the server answers <code>401</code>, it retries the same request with the next name, and keeps the one that works for the rest of the HTTP session. Names you give keep your spelling and are not repeated in the fallbacks, so unshackle tries <code>auth_headers: [\"Authorization\", \"x-secret-key\"]</code> as <code>Authorization</code>, <code>x-secret-key</code>, <code>X-Api-Key</code>.</p> <p><code>timeout</code> is the time in seconds that the client waits for data from the server.

With a value below 30 the client can time out before the first heartbeat. <code>0</code> means the default.</p> <p>In <code>--remote</code> mode unshackle turns the server's service list into synthetic CLI commands that operate against it, falling back to the tags in that <code>services</code> sub-dict when unshackle cannot fetch the list. Each synthetic command carries the server-side service's options and documentation, so <code>unshackle dl --remote &lt;TAG&gt; -h</code> shows the same help text as it does on the server. Service names resolve against the server's tags and aliases, not your local services. If the server does not offer a name to your API key, unshackle rejects the name and lists the tags it does offer.

Omit to allow all. <code>remote_only</code> bool <code>false</code> Expose only the remote service session endpoints (health, services, search, session) and disable the rest of the REST API. <code>dashboard</code> dict (unset) Developer dashboard: <code>key</code> is the API key for the read-only <code>/api/dashboard/</code> endpoints (status, remote sessions, remote session logs, jobs, keys, services, health, logs, SSE events). Unset leaves those routes unregistered. See dashboard endpoints. <code>session_ttl</code> int (s) <code>300</code> Seconds a remote session can stay idle before it expires. A remote client sends keep-alive requests to its remote session during a download, so the remote session does not expire during a long download. <code>max_sessions</code> int or null <code>100</code> Maximum concurrent remote sessions; at the cap the server evicts the oldest. Set it to <code>null</code> or <code>0</code> for no limit, which is also what <code>/api/dashboard/status</code> then reports, so a dashboard can tell \"no cap\" from a cap that happens to sit at the default. <code>history_limit</code> int <code>100</code> How many finished jobs to retain in history. <code>compression_level</code> int <code>1</code> gzip level for responses. <code>services_refresh_interval</code> int (s) <code>0</code> How often the server pulls the git-backed service repositories in <code>directories.services</code> and hot-reloads the services that changed. <code>0</code> turns it off. A service with a running or queued job, or a live remote session, is staged and swaps to the new code as soon as its last job and session finish. <code>services_staged_max_age</code> int (s) <code>0</code> How long a staged service waits for its jobs and sessions before the server swaps it in anyway. <code>0</code> waits forever. Set it on a server whose popular services never have a quiet moment. A session that is live at the swap keeps the old code until it ends; a running job keeps its old code too. <code>global_speed_limit</code> str (unlimited) Server-wide download speed cap, e.g. <code>10M</code>, <code>1.5G</code> or plain bytes/sec (same format as <code>speed_limit</code>). One shared budget across all concurrent jobs; the server ignores per-job speed limits while it is set. <code>cdm_overrides</code> list or bool (unset) Allowed per-request CDM overrides: a list of permitted device names, or <code>true</code> for any. Unset rejects every override. <code>allow_job_credentials</code> bool <code>false</code> Permit clients to supply credentials per job. <code>server_accounts</code> dict <code>{}</code> Services whose remote sessions use the server's own <code>credentials</code> and cookie files instead of the client's (see below). <code>devices</code> list (auto) Widevine devices offered; auto-filled from <code>directories.wvds</code>. <code>playready_devices</code> list (auto) PlayReady devices; auto-filled from <code>directories.prds</code>. <p>Each entry under <code>users</code> uses that user's API key as its name, and can set its own <code>services</code>, <code>devices</code>, and <code>playready_devices</code> allowlists, narrowing the global ones, plus an optional <code>username</code> used as the log label for that API key (defaults to a truncated form of the API key). A user with no <code>playready_devices</code> config key gets no PlayReady access at all, not the global list.</p> <p><code>server_cdm</code> decides whether the server runs the CDM licensing for that API key. Set it to <code>true</code> to enable every service, or to a list of service tags to enable only those. It is <code>false</code> unless the entry sets it. For a service the API key does not cover, the server tells a remote client configured with <code>server_cdm: true</code> to license with its own local CDM instead, and a client that asks anyway gets a <code>FORBIDDEN</code> error. Because a download job always licenses with the server's CDM, an API key without <code>server_cdm</code> for that service also cannot submit or retry <code>/api/download</code> jobs. Keys that have no <code>users</code> entry, such as <code>api_secret</code>, keep server CDM access.</p> <p>A remote client that picks its own device licenses the remote session with that device. It picks with <code>dl --cdm</code>, with a <code>cdm</code> entry for the service, or with <code>server_cdm: false</code> in its <code>remote_services</code> entry. The server CDM makes no licence for that remote session, with or without a limit. A service option that runs the remote session on the server's device, such as a server-identity flag, keeps the server CDM.</p> <p><code>server_cdm_max_height</code> limits the live licences the server's device makes for that API key. Set it to a height in pixels for every service, or to a map of service tag to height with an optional <code>default</code> entry. A service the map does not name or sets to <code>null</code> gets the <code>default</code>, and with no <code>default</code> it has no limit. The server compares the limit with the lowest <code>-q</code> that selects the track: the track height, or the 16:9 height from the width when that is lower. The server reads the remote client's <code>-q</code> when the remote session starts:</p> <ul> <li>With no <code>-q</code>, or a <code>-q</code> at or below the limit, the server CDM licenses the remote session. The server   refuses a live licence for a video track taller than the limit, and the client licenses that   track with its own local CDM.</li> <li>With a <code>-q</code> above the limit, the client's own local CDM licenses every track of the remote session.   The service sees the DRM system and security level of the client's device. A client with no   local CDM gets a <code>SERVER_CDM_CAPPED</code> error.</li> <li>A download job must pass a <code>quality</code> at or below the limit, and must not set <code>best_available</code> or   a <code>HYBRID</code> range. <code>HYBRID</code> always keeps the lowest Dolby Vision track, at any quality. A job with   no <code>quality</code>, with a higher one, with <code>best_available</code>, or with <code>HYBRID</code> gets a <code>SERVER_CDM_CAPPED</code>   error. The server checks the values the job runs with, after it applies the service defaults   and the <code>serve:</code> download defaults.</li> </ul> <p>The limit protects the server's device, not the content keys. For a Widevine track, a server vault still supplies a content key at every height. A PlayReady track never reads the vault, so above the limit it always goes to the client's device. A licence for a lower track can carry the content key of a higher track when the service shares one content key between them. With server accounts enabled, a client that reports a stronger device than it holds makes the server's account request those manifests; the licence server still refuses its challenge.</p> <p><code>server_vault</code> lets a remote session that the client's own device licenses take content keys from the server vault. Set it to <code>true</code> for every service, or to a list of service tags. It is <code>false</code> unless the entry sets it, and <code>server_cdm</code> for a service implies it. The server looks up every KID of the track in its vault and makes no live licence. A track that the vault does not hold goes back to the client's device. When the service runs the remote session on the server's own device (a service option, such as a server-identity flag), the client's own vaults, and the server vault with this grant, are the only source, and a missing content key stops the download.</p> <p><code>admin</code> is a boolean that lets the API key run the maintenance endpoints (clear-cache, clear-temp, refresh-services). It is <code>false</code> unless the entry sets it. Keys that have no <code>users</code> entry, such as <code>api_secret</code>, keep that access.</p> <p>A <code>tier</code> names an entry under <code>serve.tiers</code>, which holds the settings that several API keys share. Today a tier carries <code>rate_limit</code>, the requests per hour that API key may make; an API key can also set its own <code>rate_limit</code>, which wins over its tier's. An API key with neither has no limit. Going over the limit answers <code>429</code> with a <code>Retry-After</code> header. The server keeps a fixed window rather than a sliding one: it opens on the first request and resets an hour later. A <code>tier</code> that names no entry under <code>serve.tiers</code>, or a <code>rate_limit</code> that is not a positive whole number, stops the server at startup, because the alternative is an API key that silently gets no limit. The rate limit never applies to the dashboard key, and never to <code>/api/health</code>.</p> <p><code>server_accounts</code> lists, per service, the accounts the server lends to remote sessions. A remote session for a listed service ignores the credentials, cookies, and cache the client sends and uses one of the server's own profiles from <code>credentials</code>. For a service that is not listed the server never uses its own accounts: a client that sends nothing authenticates with nothing.</p> <pre><code>credentials:\n  EXAMPLE1:\n    ca_main: user1@example.com:pw1\n    eu_box: user2@example.com:pw2\n    shared: user3@example.com:pw3\n\nserve:\n  server_accounts:\n    EXAMPLE1:\n      ca_main: ca             # one country\n      eu_box: [gb, fr, de]    # a list of countries\n      shared: global          # any region\n    EXAMPLE2: true            # every profile (or the single credential), any region\n</code></pre> <p>Each entry under a service names a profile from <code>credentials</code>, or a cookie file <code>cookies/&lt;TAG&gt;/&lt;profile&gt;.txt</code> for a service that has no credentials. Its value is the region or regions that account works in: a two-letter country code, a list of them, or <code>global</code>. Quote <code>no</code> (Norway), because YAML reads the bare word as <code>false</code>.</p> <p>The region of a remote session is the country the client asked for with <code>--proxy</code> (<code>ca</code>, <code>ca1</code>, <code>provider:ca</code>), the server's own region with <code>--no-proxy</code>, or the client's own region otherwise. A full proxy URI carries no country, so with one only a <code>global</code> account matches. The server picks the profiles that cover that region (or are <code>global</code>) and rotates through them round-robin, one account per remote session. With no matching account it rejects the remote session. These services ignore the client's <code>-p/--profile</code>.</p> <p>Cookies come only from the profile's own file (<code>cookies/EXAMPLE1/ca_main.txt</code>; the server does not read a bare <code>cookies/EXAMPLE1.txt</code>), and each account keeps its own persistent cache under <code>cache/_accounts/EXAMPLE1/&lt;profile&gt;/</code>, so refreshed tokens survive the remote session but never cross accounts. <code>serve</code> refuses to start when a listed profile has neither an entry under <code>credentials</code> nor a cookie file. <code>/api/search</code>, <code>/api/list-titles</code> and <code>/api/list-tracks</code> use the same pool, matched on the client's reported region, and return <code>FORBIDDEN</code> to an API key without the opt-in. Rotation is per process and does not track which accounts are in use, so concurrent remote sessions can share one account.</p> <p>A <code>users</code> entry opts in to those accounts with <code>server_accounts: true</code> (every listed service) or a list of service tags. It is off unless set: an API key without it authenticates with the credentials the client sends, as for any other service, and <code>/api/services</code> does not advertise the server's accounts to it. API keys with no <code>users</code> entry, such as <code>api_secret</code>, keep access.</p> <p><code>server_proxy</code> decides whether that API key may use the proxy providers the server has configured. There is no implicit access: only the boolean <code>true</code> on the API key's <code>users</code> entry grants it, and an API key without a <code>users</code> entry has no access either. Without the opt-in the server never spends its own proxy subscriptions on a remote client: not to resolve a country code in <code>proxy</code>, not to match the client's region, and not for a service geofence. This applies to remote sessions, search, title lists, and <code>/api/download</code> jobs alike. Such a client must send a full proxy URI, or <code>no_proxy</code> to accept the server's own connection. Set <code>server_proxy: true</code> to let that API key send a country code or a <code>provider:country</code> value, and to let the server pick a proxy for the client's region and for a service geofence. The client reports its own region; a client that reports none is not blocked.</p> <pre><code>serve:\n  api_secret: change-me\n  remote_only: true\n  services: [EXAMPLE1, EXAMPLE2]\n  services_refresh_interval: 3600   # pull the service repositories hourly and reload what changed\n  # server-wide download defaults (same keys as the `dl:` block)\n  downloads: 3\n  best_available: true\n  tiers:\n    bot: { rate_limit: 600 }      # requests per hour, for every key on this tier\n  users:\n    a1b2c3d4:                     # this user's API key\n      services: [EXAMPLE1]        # may only use EXAMPLE1\n      tier: bot                   # 600 requests/hour; 429 with Retry-After once over\n    e5f6a7b8:\n      server_cdm: true            # this key may have the server do the licensing\n      server_cdm_max_height: 1080 # above 1080p the client licenses with its own device\n    c9d0e1f2:\n      services: [EXAMPLE1, EXAMPLE2]\n      server_cdm: [EXAMPLE1]      # the server licenses only EXAMPLE1; EXAMPLE2 needs a local CDM\n      server_accounts: [EXAMPLE1] # may authenticate EXAMPLE1 with one of the server's own accounts\n      server_proxy: true          # this key may also use the server's proxy providers\n    f3a4b5c6:\n      services: [EXAMPLE1]\n      server_vault: [EXAMPLE1]    # the client's device licenses; the server vault still serves keys\n</code></pre> <p><code>dl</code> keys inside <code>serve</code></p> <p>Most <code>dl</code> flag keys (<code>downloads</code>, <code>workers</code>, <code>best_available</code>, and so on) can be set directly inside <code>serve</code>, where they apply to every request the server handles.

A <code>serve</code> instance with <code>server_cdm</code> flags a pair the same way when a remote client reports it, so a server whose <code>key_vaults</code> hold no <code>SQLite</code> entry cannot remember a bad content key.</p>"},{"location":"reference/configuration/vaults/#vault_timeout","title":"<code>vault_timeout</code>","text":"<ul> <li>Type: <code>float</code> \u00a0\u00b7\u00a0 Default: <code>10.0</code></li> </ul> <p>Timeout in seconds for vault operations.
