sort_subtitles applied the language sort before the type sort. Python sorts
are stable, so the last pass wins and type became the major key: every forced
track, then every normal, then every SDH, each block ordered by language. In a
title with many languages this put a track far from its own SDH version, for
example Finnish at track 5 and Finnish SDH at track 42.
Add a group_by parameter that selects the major key. "type" is the default and
keeps the current order byte for byte. "language" swaps the two passes so each
language stays next to its own variants. Read it from the new subtitle.group_by
config key.
Also correct the docs: type_priority was described as sorting the variants
within each language, which was never true. It ranks the types across all
languages.
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.
