`Composition::aaf_mob_id` is documented as a read identity: writers generate
fresh format identifiers and never preserve it. The roundtrip test compared
whole compositions after the second write, so it broke as soon as #1098
exposed the field. Compare them with the id cleared, as the surrounding
comment already described.
* craft-audio: integer PCM of WAV and AIFF files bit for bit, and minimal files around it
wav_pcm and aiff_pcm (feature decode-native) return a file's integer PCM as stored
(RawPcm: little-endian interleaved bytes, 8-bit unsigned, with channels, rate and
bits), built on the existing WAV and AIFF chunk parsers. pcm_wav_file,
pcm_wav_header, pcm_aiff_file and pcm_aiff_header (feature pcm-encode) write the
44-byte canonical WAVE header and the plain AIFF header around such bytes.
For essence embedded in AAF and OMF files, which is moved bit for bit and whose
descriptors hold a bare header as a summary. The writers are FilmCraft's
(filmcraft-interchange wav.rs); the readers replace its second WAV/AIFF parser
with this crate's.
* craft-timeline: exact media time, reports, media paths, ALE and CMX 3600 EDL
New crate for editorial timeline interchange (#782), moved from FilmCraft at
4bec22bd:
- time: filmcraft-time whole (Tick, FrameRate, TimeRange, SMPTE timecode,
feet+frames, typed-timecode parsing) with its tests.
- report: Report / Level / ReportEntry.
- path: file URL and path conversion, relative references joined to a folder.
- rate: timebase+ntsc and floating rates to exact rates, MAX_RATE.
- ale: AleDoc, parse, write, standard heading and columns.
- edl: the parser (events, lines, timecode fields, M2, AUD, comment extensions),
the frame-rate guess, and the line layout of the writer, on frame counts.
- Format, detect_text, decode_text.
Each format module gives the document as the format writes it. Mapping onto an
application's timeline stays in the application.
* craft-timeline: strip a UTF-8 byte order mark when parsing ALE files
An ALE saved with a BOM was refused as "not an ALE file": the mark made the
first line something other than "Heading".
Ported from storytold/filmcraft#4531.
* craft-aaf: AAF (Edit Protocol) and OMF 2.0 readers and writers over one composition model
New crate (#782), moved from FilmCraft's filmcraft-interchange at 4bec22bd:
the mob-style model types of comp.rs, aaf/{ids,store,read,write}.rs and
omf/{bento,read,write}.rs, with their structural and hostile-input tests
rebuilt on model documents instead of FilmCraft projects.
The container is craft-cfb, time and reports are craft-timeline's, and the
WAVE/AIFF wrappers of embedded PCM are craft-audio's. The writer's identity
(company, product, version, AAF product id) is passed in instead of being
FilmCraft's. The private tags and properties FilmCraft wrote keep their names
so existing files read back.
The mapping between the model and an application's project stays in the
application.
