Only merge back tracks from another manifest, so a drifted id no longer duplicates a rung or wipes the main manifest's own subtitles. track_is_encrypted now recognises an ISM ProtectionHeader.
Error messages named the resolved language for a user who only ever defaulted to orig. Audio tracks now carry is_original, resolved through Tracks.by_language so it agrees with the downloader.
Detect the dot/space style from the full folder template instead of per segment, so `{artist}/{album} ({year})` no longer yields `Some.Artist/Some Album (2025)`. Also drops empty `[]` groups like the existing `()` handling and removes redundant cleanup passes.
- Clean up redundant spaces and separators when conditional tags (e.g. {year?}) are omitted.
- Strip leading and trailing spaces and dots in sanitize_filename and TemplateFormatter.
- Prevent FileNotFoundError [WinError 3] caused by trailing spaces in Windows directory paths.
UNITY_MATRIX emitted 11 int32s instead of 9, oversizing mvhd/tkhd so pymp4 desynced and fTTML subtitles yielded no cues. Also rewrites PIFF senc to CENC so shaka can decrypt Smooth, labels HEV1 as hev1, and raises when a fragment survives decryption still carrying a sample-encryption box.
Smooth fragments set tfhd sample_description_index=2 against a server init carrying a second, identical sample entry. A lone entry left that dangling: mp4decrypt skipped every such fragment silently and demuxers stopped after the first, yielding a file that looked fine but was almost entirely encrypted.
Only fall back to Title.language when the manifest labels nothing, and reject und as firmly as a missing tag. Exported direct-URL subtitles now replace the re-parsed set, and fetch failures stay distinct from parse failures.
Stop remounting adapters on shared sessions (restores dropped 429/5xx retries, ends 16-conn pool starvation, pool sized to 64); defer DRM vault write-backs off the global lock; add mux output_path groundwork for future parallelism.
Detect an encv/enca sample entry surviving decryption (moov-scoped 4CC scan) and force a repack so mkvmerge isn't first-FourCC-locked to a generic encrypted codec; warn if one persists after repacking.
Closes#142
Add is_revocation()/REVOCATION_CODES and centrally raise DeviceRevoked when a license fault carries a device/cert revocation HRESULT, so any service surfaces it without its own decoding.
Speedtest failures print an exit-code note instead of an empty section,
the report file writes progressively again (utf8 rewrite at the end),
and pytest-asyncio's py3.14 deprecation warning is filtered.
Adds machine info to the report header, multiprocess and strided-split
runs, hedge/slow-tail cases, the rnet path, and the leak regression
tests; ps1 reports save as utf8 and expected failures no longer render
as NativeCommandError blocks.
A leaked racer could retry and reopen its .!dev once dl.py cleared the
global cancel flag for the next track (WinError 32 at cleanup). A
batch-local abort event set at teardown makes its exit unconditional.
Also join terminated mp children and detect one that dies silently.
Also throttle hedge-median recompute to 0.5s, cache replace_fields format
patterns and short-circuit when no $ token, and stream HLS merge with
copyfileobj. Adds test_dash_collapse and live A/B tooling.
bench_downloader.py sweeps the unified downloader over synthetic
loopback segments (latency/rate shaping, fault injection, hedge and
sweep-safety checks) or real URLs, with --procs and --no-read1 A/B
flags. live_manifest_test.py drives the full DASH/HLS/ISM pipeline
against 11 public streams on 8 CDNs; bench-urls/ holds reproducible
real-CDN URL lists.
Unconditional read1 for every segmented download paid a per-TLS-record
Python iteration on all segments and capped single-process throughput
at ~160 MB/s (253 MB/s with blocking full-chunk reads, measured on a
fast CDN). A segment can only be claimed once a hedge racer exists for
it, so fine-grained claimed() checks are needed only during an actual
race: download() now takes a racing predicate and workers pass the
hedged-set membership check.
One CPython interpreter caps sustained segment throughput at ~160 MB/s;
spawned children each run the existing thread-pool path on a contiguous
chunk of the batch, reaching NIC line rate on fast CDNs. Opt-in via
--download-processes (default 1), engaged only for 24+ segment batches.
Sessions are rebuilt per child from a picklable spec; RnetSession falls
back to a single process when it has no impersonate preset.
