# 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 for `wasm32-unknown-unknown`.
- Containers (MP4/MOV, Matroska/WebM), bit-level I/O (`craft_media::bitstream`) and shared
  identifiers (`CodecId`, `CodecParams`) come from [`craft-media`](../media/README.md).
