Sibling case to #308: when a fragmented MP4 segment begins with a sidx
box (no ftyp/styp/moof at the file root), Mp4InputFormat._canReadInput
returned false, causing Input.getTracks() to throw
UnsupportedInputFormatError.
This shape is standard in CMAF when the DASH on-demand profile is used
or when HLS playlists are derived from one (Vimeo's vod-adaptive-ak CDN,
for example). The segment is still a valid ISOBMFF fragment — the sidx
just sits before the moof.
Adds 'sidx' alongside the existing 'moof' check so the format probe
accepts these segments, and a focused regression test that fails on
the previous behaviour.
- Add support for fMP4 segments
- Add initInput (supported by ISOBMFF and MPEG-TS)
- Input.isSupported()
- Refactored file size retrieval logic, the file size can now be retrieved alongside the first read.
- Add support for unsized UrlSources
- Add support for multiple trun boxes in a row for the same track (as the spec literally says lol)
- Add support for more M3U8 features
- Fix faulty line reader
- MPEG-TS improvements: support video parameters not in first packet, support better key frame detection, support extension PES packets without PTS
- Fix reorder buffer being 1 element too small
* Read ID3v2 tags from WAV file
* remove js import

* revert slicing in wave-demuxer.ts and add id3.ts for further sharing
* Add `writeId3Tag` to the `WavOutputFormat` constructor options
* add more context in private and public APIs that it's non-standard
* compare actual values in the test with real file
* remove unnecesarry double slice requesting
* trim test audio file (i tried my best to preserve ID3, including artwork)
* Couple of code cleanups
* const -> using
* Fix linting errors
