* craft-video: AV1 decoder from FilmCraft (`av1-decode` feature) FilmCraft's crates/av1 at 4c0d2ad7 becomes craft_video::av1::decode. The encoder moves to av1/encode and is still exported from craft_video::av1. Feature av1 now turns on av1-decode and av1-encode, so either half can be built without the other. The ignored speed tests no longer read the thread CPU clock (FilmCraft used rustix for it). craft_video::budget (the picture memory budget from DeckCraft's bitstream crate) is added for the next commit. craft-video is built at opt-level 3 in the dev profile, as FilmCraft built its codecs. * craft-video: AV1 decoder hardening from DeckCraft's copy - The picture store (eight reference slots, the new frame, frames in flight) is checked against a memory budget before a frame is allocated; Decoder::set_memory_budget. - Non-uniform tile spacing is refused past MAX_TILE_COLS columns or MAX_TILE_ROWS rows. * craft-video: AV1 fuzz seeds are 64x64 so SVT-AV1 2.x can encode them FilmCraft's seeds were 64x48; the SVT-AV1 2.3 on the Ubuntu runners refuses a source under 64 lines, and an encoder that exists but fails is a test failure, not a skip.
craft-video
Clean-room pure-Rust video codecs for the Craft apps, one feature per codec: DNxHD/DNxHR, VP8, ProRes and H.264.
- Input and output are byte slices and planar sample buffers; the crate opens no files itself and performs no filesystem I/O.
- Implemented from published standards and RFCs (SMPTE ST 2019-1, RFC 6386, SMPTE RDD 36 and ITU-T H.264).
- Tested against ffmpeg as an external oracle with roundtrips, hostile fuzzing, and conformance vectors.
No
unsafe, no panics on corrupt streams. Builds forwasm32-unknown-unknown. - Containers (MP4/MOV, Matroska/WebM), bit-level I/O (
craft_media::bitstream) and shared identifiers (CodecId,CodecParams) come fromcraft-media.
Cargo features
No codec feature is on by default.
