Crate rav1e[−][src]
rav1e is an AV1 video encoder. It is designed to eventually cover all use cases, though in its current form it is most suitable for cases where libaom (the reference encoder) is too slow.
Features
- Intra and inter frames
- 64x64 superblocks
- 4x4 to 64x64 RDO-selected square and 2:1/1:2 rectangular blocks
- DC, H, V, Paeth, smooth, and a subset of directional prediction modes
- DCT, (FLIP-)ADST and identity transforms (up to 64x64, 16x16 and 32x32 respectively)
- 8-, 10- and 12-bit depth color
- 4:2:0 (full support), 4:2:2 and 4:4:4 (limited) chroma sampling
- Variable speed settings
- Near real-time encoding at high speed levels
Usage
Encoding is done through the Context struct. Examples on
Context::receive_packet show how to create a Context, send frames
into it and receive packets of encoded data.
