vpx: VP8 and VP9 Encoder
The vpx codec supports both VP8 and VP9 formats. However, VP9 is disabled in versions before 0.15 because it was too slow to be useful.
Please also note that VP8 currently only supports
YUV420P colour subsampled data, which leads to some visual degradation, especially with text.
Build and installation
When building xpra from source,
vpx support is included by default.
For encoding and decoding support, you should install
You will need libvpx 1.4 for full VP9 support.
