--- Comment #1 from Jan Beich <jbeich at FreeBSD.org> ---
Can someone on x11@ list check for regressions? For example,

$ mpv --no-config --hwdec=vaapi
--ytdl-format='bestvideo[height<=2160][vcodec=vp9]+bestaudio'
'https://www.youtube.com/watch?v=1La4QzGeaaQ'

- SandyBridge, IvyBridge don't support hybrid decoding. VP9 decoding should be
in software while H264 in hardware.
- Haswell, Broadwell, Skylake should use hybrid VP9 decoding for 8bit streams
with resulotion up to 2160p. Expect CPU usage to drop by ~50%.
- Kabylake or newer shouldn't use hybrid decoding because VP9 is supported
natively.
