CLI Reference

A complete reference for every unshackle command, subcommand, and flag. Commands are grouped by purpose:

  • dl: the download pipeline (the command you use most).
  • search: find titles on a service.
  • import: rebuild a download from an export file.
  • cfg, env: manage configuration and the environment.
  • kv: Key Vault operations.
  • wvd, prd: Widevine / PlayReady device management.
  • serve: run the local CDM + REST API server.
  • util: helper media utilities.

Getting help on any command

Every command accepts -h, --help, or -?. For example unshackle dl --help or unshackle wvd new --help. Service-specific arguments for dl and search (such as a title ID or search query) are defined by each service, so check unshackle dl SERVICE --help for those.


Root command

unshackle [OPTIONS] COMMAND [ARGS]...

unshackle: Modular Movie, TV, and Music Archival Software.

Every invocation prints a banner and, when update_checks is enabled in your config, checks for a newer release.

Option Description
-v, --version Print version information and exit.
-d, --debug Enable DEBUG-level logs and JSON debug logging. Silences noisy HTTP libraries unless debug_requests is set in config.
-h, --help, -? Show help and exit.

Commands are auto-discovered, so third-party command modules dropped into the commands directory appear automatically.


dl

The download command. It is itself a group whose subcommands are the installed streaming services, so an invocation always has three layers:

unshackle dl [OPTIONS] SERVICE [SERVICE ARGS...]
  • OPTIONS: every flag below, parsed at the dl level.
  • SERVICE: a service tag (e.g. EXAMPLE1, EXAMPLE2). Tags are case-insensitive and honour each service's aliases (example+, EXAMPLE2, etc. all resolve to the same tag).
  • SERVICE ARGS: the title, URL, or ID, plus any service-specific options. These belong to the service, not to dl.

Typical downloads

# Best available 1080p SDR of a title
unshackle dl -q 1080 EXAMPLE 81234567

# 4K HDR10, English audio + subs, from a URL
unshackle dl -q 2160 -r HDR10 -l en EXAMPLE "https://www.example.com/..."

# A season range, HEVC video, EC3 audio
unshackle dl -w S01-S03 -v H.265 -a EC3 SERVICE TITLE-ID

Config-driven defaults

Any dl flag can be given a default under the dl: section of unshackle.yaml, and per-service under services.<TAG>.dl. Explicit command-line values (and environment values) always win over both; service defaults only fill in options you did not set. See the configuration file guide.

Quality, codec, bitrate & range

Flag Default Description
-p, --profile - Profile for credentials and cookies.
-q, --quality best Resolution(s), comma-separated, e.g. 1080,720. -q 1080 also matches anamorphic tracks by 16:9 canvas.
-v, --vcodec any Video codec(s). Accepts names or values: AVC/H.264, HEVC/H.265, VC1, VP8, VP9, AV1.
-a, --acodec any Audio codec(s), comma-separated. Accepts AAC, AC3/DD, EC3/DD+/eac3/ddp, AC4, OPUS, OGG/vorbis, DTS, ALAC, FLAC.
-vb, --vbitrate highest Exact video bitrate in kbps.
-ab, --abitrate highest Exact audio bitrate in kbps.
-vb-range, --vbitrate-range - Video bitrate range in kbps, e.g. 6000-7000; picks highest within. Mutually exclusive with --vbitrate.
-ab-range, --abitrate-range - Audio bitrate range in kbps, e.g. 128-256. Mutually exclusive with --abitrate.
-r, --range SDR Colour range(s): SDR, HLG, HDR10, HDR10P (HDR10+), DV, HYBRID.
-c, --channels - Audio channels; matches sub-layouts (5.1 ≈ 6.0).
-naa, --noatmos off Exclude Dolby Atmos audio tracks.
--worst off Pick the lowest bitrate within the requested quality. Requires -q.
--best-available off Continue with the best available if a requested resolution/language is absent, instead of failing.
-rvb, --real-video-bitrate off Probe real media size for true video bitrates, overriding the manifest.
-rab, --real-audio-bitrate off Same for audio (slower).

HYBRID range

-r HYBRID fetches both HDR10/HDR10+ and Dolby Vision and merges them with dovi_tool. It requires the dovi_tool binary on your PATH.

Language & subtitles

Flag Default Description
-l, --lang orig Language(s) for both video and audio. orig = the title's original language; e.g. orig,en.
-vl, --v-lang - Video-only language (overrides -l for video).
-al, --a-lang - Audio-only language (overrides -l for audio).
-sl, --s-lang all Subtitle language(s).
--require-subs - Required subtitle langs; keeps all subs only if these exist. Cannot combine with --s-lang.
-fs, --forced-subs off Include forced subtitle tracks.
--exact-lang off Exact matching only: -l es-419 matches es-419, not es-ES.
--sub-format - Output subtitle format (SRT/srt, VTT/webvtt, ASS/ssa, TTML, SMI, ...), or original to keep the source format.

The special language tokens orig, all, and best are honoured everywhere a language is expected.

Title & episode selection

Flag Description
-w, --wanted Wanted episodes, e.g. S01-S05,S07, S01E01-S02E03. Supports exclusions with a leading - (e.g. -S03).
--select-titles Interactively select titles (series only). Cannot combine with -w.
--latest-episode Download only the single most recent episode.
--list-titles List titles only; do not download.

Track-type inclusion / exclusion

Keep only certain track types, or skip certain track types. Attachments are always kept.

Include-only Skip
-V, --video-only -nv, --no-video
-A, --audio-only -na, --no-audio
-S, --subs-only -ns, --no-subs
-C, --chapters-only -nc, --no-chapters
Flag Description
-ad, --audio-description Include descriptive (audio-description) tracks.
--skip-subtitle-errors Skip a failed subtitle instead of aborting the title. Video/audio failures remain fatal.

Output, muxing & files

Flag Description
--split-audio Write a separate output file per audio codec instead of merging. Defaults to config muxing.merge_audio.
--merge-video Mux all selected video tracks into one file. Defaults to config muxing.merge_video.
-o, --output Override the output directory for this run.
--no-folder Disable folder creation for TV shows.

--enrich Override show title/year from the external source. Requires one of --tmdb, --imdb, or --animeapi.

DRM, keys & decryption

Flag Description
--cdm-only / --vaults-only Use only the CDM, or only Key Vaults, for key acquisition.
--skip-dl Skip the download but still retrieve keys.
--export Export track info and keys to a JSON file in the exports directory.

Network & proxy

Flag Description
--proxy Proxy URI, a 2-letter country code resolved from configured providers, or provider:region (e.g. nordvpn:ca, gluetun:us, protonvpn:de:berlin).
--no-proxy Force-disable all proxy use.
--no-proxy-download Bypass the proxy for segment downloads only (manifest, licence, and auth stay proxied).
--remote Use a remote unshackle server.
--server Name a remote server from the remote_services config.

Concurrency, caching & listing

Flag Default Description
--workers downloader default Per-track download threads.
--downloads 1 Number of tracks downloaded concurrently.
--no-cache off Bypass the title cache.
--reset-cache off Clear the title cache.
--list off List available/would-be-downloaded tracks; do not download.
--slow - Inter-title delay. Bare --slow = 60-120s; --slow 20-40 = custom range (minimum 20s).

Some flags cannot be combined

--require-subs and --s-lang; --select-titles and --wanted; --worst requires --quality; --vbitrate and --vbitrate-range (and the audio equivalents) are mutually exclusive.


Search a service for titles. Like dl, search is a group whose subcommands are the installed services, and it reuses dl's authentication, cookie, and proxy machinery.

unshackle search [OPTIONS] SERVICE [QUERY...]

The query syntax is defined per service. Results are printed as a tree of titles with their service IDs. Feed an ID straight into dl.

Option Description
-p, --profile Profile for credentials and cookies.
--proxy Proxy URI, 2-letter country code, or provider:region.
--no-proxy Force-disable all proxy use.

Example

unshackle search EXAMPLE "My Show"
unshackle search -p myprofile EXAMPLE "Another Show"
unshackle search --proxy nordvpn:ca SERVICE "query"

import

Reconstruct a download (download → decrypt → mux) from an --export JSON file without re-contacting the service. It re-fetches the manifest, injects the stored keys, and then runs the normal dl pipeline. The service tag is read from the export file, not passed by you.

unshackle import EXPORT_FILE [DL_ARGS...]

Any dl options placed after the file are forwarded verbatim, so you can override quality, range, proxy, and so on.

Example

unshackle import export.json
unshackle import export.json -r HDR10 --proxy US

The export file must be a valid v2 export (created by a current build of unshackle via dl --export) and must contain a service tag.


cfg

Read, set, delete, or list configuration values in unshackle.yaml without hand-editing YAML.

unshackle cfg [KEY] [VALUE] [OPTIONS]
Argument / Option Description
KEY Dotted path into the config, e.g. tag, serve.api_secret, directories.downloads.
VALUE Value to set. Parsed as a Python literal when possible, so true, 123, ['a','b'], and {'k':1} become real types; bare words stay strings.
--unset Remove the configuration value.
--list List all set configuration values.

Comments are stripped

Writing a value through cfg rewrites the YAML file and removes all comments from it. If your config relies on comments, edit it by hand instead. Setting a value and using --unset together is an error.

Example

unshackle cfg --list                        # print entire config
unshackle cfg serve.api_secret              # read a nested key
unshackle cfg tag MYGROUP                    # set a string
unshackle cfg update_checks false           # literal → boolean False
unshackle cfg directories.downloads /mnt/dl # set a nested path
unshackle cfg tag --unset                    # remove a key

env

Inspect and manage the project environment.

unshackle env COMMAND [ARGS]...

env check

unshackle env check

Prints a dependency table (Category / Tool / Status / Required / Purpose) showing which external tools resolve on your PATH, and a summary of how many required tools are installed.

Category Tools
Core FFmpeg*, FFprobe*, MKVToolNix*, mkvpropedit*
DRM shaka-packager*, mp4decrypt, ML-Worker
HDR dovi_tool, HDR10Plus_tool
Subtitle SubtitleEdit, CCExtractor
Player FFplay, MPV
Network HolaProxy, Caddy, Docker, git

* required; all others are optional.

env info

unshackle env info

Shows where the config was loaded from (or lists the candidate config locations if none was found) and prints a table of every configured directory (downloads, temp, cache, cookies, logs, exports, WVDs, PRDs, services, and more).

env clear

Clear an environment directory. The directory is emptied and recreated, and the number of files and bytes freed is reported.

Command Description
unshackle env clear cache [SERVICE] Clear the cache directory, or just one service's cache subdirectory.
unshackle env clear temp Clear the temp directory.

Example

unshackle env check
unshackle env info
unshackle env clear cache
unshackle env clear cache EXAMPLE   # one service only
unshackle env clear temp

kv

Manage Key Vaults. Vaults are configured under key_vaults in unshackle.yaml, each with a name, a type (sqlite, mysql, http, api), and type-specific options. Service tags are normalised automatically.

unshackle kv COMMAND [ARGS]...

kv copy TO_VAULT FROM_VAULT...

Copy keys from one or more source vaults into a destination vault. Rows with matching KIDs are skipped unless the existing row has no key; existing data is never altered or deleted.

Option Description
-s, --service Only copy data for a specific service.
-l, --local-only Only copy data for services installed locally. Mutually exclusive with --service.

kv sync VAULT...

Ensure two or more vaults hold the same set of keys, essentially a chained bidirectional copy. Requires more than one vault. Accepts the same --service / --local-only options as copy.

kv add FILE SERVICE VAULT...

Add content keys to one or more vaults for a service. FILE contains one KID:KEY pair per line (32 hex : 32 hex, UTF-8). Lines that don't match are skipped.

kv search KID

Search configured vaults for a KID (32 hex characters, no dashes) and report any matching key.

Option Description
-s, --service Limit the search to a specific service tag.
-v, --vault Limit the search to a specific configured vault by name.

Note

Remote vaults cannot be enumerated without a service, so pass --service when searching them.

kv prepare VAULT...

Create service tables on vaults that use tables, for every installed service, where they don't already exist.

Example

unshackle kv copy main backup1 backup2
unshackle kv copy main backup -s EXAMPLE
unshackle kv sync main mysql_vault
unshackle kv add keys.txt EXAMPLE main backup
unshackle kv search 0123456789abcdef0123456789abcdef -s EXAMPLE -v main
unshackle kv prepare main mysql_vault

wvd

Manage Widevine Device (.wvd) files. Devices live in the configured WVDs directory.

unshackle wvd COMMAND [ARGS]...
Command Description
wvd add PATHS... Validate and move one or more .wvd files into the WVDs directory.
wvd delete NAMES... Delete .wvd files by name (without extension). Prompts for confirmation.
wvd parse PATH Parse a .wvd and print its System ID, security level, type, flags, and client info. Relative paths resolve against the WVDs directory.
wvd dump WVD_PATHS... OUT_DIR Extract a device's contents (metadata, private key, client ID, VMP) into OUT_DIR/<name>/. With no paths, dumps every WVD in the WVDs directory.
wvd new NAME PRIVATE_KEY CLIENT_ID [FILE_HASHES] Create a new .wvd from a PEM private key and a ClientIdentification blob, optionally with a VMP (FileHashes) blob.

wvd new options:

Option Default Description
-t, --type Android Device type.
-l, --level 1 Security level (1-3).
-o, --output WVDs dir Output directory.

Example

unshackle wvd dump device.wvd ./out_dir
unshackle wvd new "Nexus 6P" private_key.pem client_id.bin vmp.bin -t ANDROID -l 3

prd

Manage PlayReady Device (.prd) files. Devices live in the configured PRDs directory. Built on pyplayready.

unshackle prd COMMAND [ARGS]...

prd new PATHS...

Create a new .prd. Provide either a single folder containing zgpriv.dat (group key) and bgroupcert.dat (group certificate), or two file paths (group key, then group certificate).

Option Description
-e, --encryption_key Optional device ECC private encryption key (generated if omitted).
-s, --signing_key Optional device ECC private signing key (generated if omitted).
-o, --output Output directory or .prd file path.

prd new will not overwrite an existing file.

prd reprovision PRD_PATH

Reprovision an existing device by replacing its leaf certificate and keys. The device must support reprovisioning (version 3 or higher). Accepts the same -e / -s / -o options; defaults to overwriting the device in place.

prd test DEVICE

Test a device against the Microsoft PlayReady demo server and print the returned keys.

Option Default Description
-c, --ckt aesctr Content key encryption type: aesctr or aescbc.
-sl, --security-level 2000 Minimum security level: 150, 2000, or 3000.

Example

unshackle prd new ./device_folder/
unshackle prd new zgpriv.dat bgroupcert.dat -o /out/dir
unshackle prd reprovision mydevice.prd
unshackle prd test mydevice.prd -sl 3000 -c aescbc

serve

Serve your local Widevine/PlayReady devices and the REST API for remote access. Built on aiohttp.

unshackle serve [OPTIONS]
Option Default Description
-h, --host 127.0.0.1 Host to serve from.
-p, --port 8786 Port to serve from.
--caddy off Also serve through Caddy (requires the caddy binary and a Caddyfile).
--api-only off Serve only the REST API, not the CDM endpoints. Incompatible with --no-widevine/--no-playready.
--no-widevine off Disable the Widevine CDM endpoints.
--no-playready off Disable the PlayReady CDM endpoints.
--no-key off Disable API-key authentication (allows all requests).
--debug-api off Include tracebacks/stderr in API error responses.
--debug off Enable debug logging for API operations.
--remote-only off Expose only the remote service session endpoints (health, services, search, session). Implies --api-only.

WVD files in the WVDs directory and PRD files in the PRDs directory are auto-loaded. The REST API lives under http://<host>:<port>/api/, with Swagger UI at /api/docs/ and a health check at /api/health (exempt from auth).

Configure api_secret first

Unless you pass --no-key, serve.api_secret must be set in your config. Requests authenticate with the X-Secret-Key header. Running with --no-key disables authentication entirely and should only be used on a trusted, private network.

unshackle.yaml
serve:
  api_secret: "your-api-secret"
  users:
    your-secret-key:
      devices: ["device_name"]           # Widevine devices
      playready_devices: ["device_name"] # PlayReady devices
      username: user

Example

unshackle serve
unshackle serve -h 0.0.0.0 -p 8080
unshackle serve --api-only
unshackle serve --remote-only
unshackle serve --caddy

util
