Formats supported

Format Decoder Encoder Notes
YUV4MPEG2 ✅ ❌ Supports most bitdepth and chroma subsampling. Library limited, not format limited.
Decoding via S.O.N.G/Ignite
H.264 ❌ ✅ Supports 8-bit and 10-bit; 4:0:0, 4:2:0, 4:2:2, 4:4:4 chroma subsampling.
Encoding via x264 into .h264 bitstream.
H.265 ❌ ❌
VP9 ❌ ❌
AV1 ✅ ✅ Supports 8-bit, 10-bit and 12-bit; 4:0:0, 4:2:0, 4:2:2, 4:4:4 chroma subsampling.
Decoding via dav1d from .ivf bitstream
Encoding via libaom-av1 into .ivf bitstream.

TODO

  • No SAR/PAR handling.
  • No color primary / transfer / matrix coefficients handling.

Build tags

Several Golang build tags exist to change which features are included in the project.

disable_library_[library]

This tag disables support for the specified library dependencies.

Current implemented [library]: libdav1d, libaom, libx264, libvmaf.
