Public bug reported:

Hi,

using mpv to view a h264 video displays the following error message:

$ mpv foo.mkv
 (+) Video --vid=1 (*) (h264 1440x924 25.000fps)
[ffmpeg] AVHWDeviceContext: Failed to query surface attributes: 20 (the 
requested function is not implemented).
[vo/gpu/vaapi-egl] failed to retrieve libavutil frame constraints
Using hardware decoding (vaapi).
[...]

The video is correctly displayed, though.

There are 2 drivers, a free (i915) and a non-free (iHD):

-rw-r--r-- 1 root root  8098968 Feb  6  2020 
/usr/lib/x86_64-linux-gnu/dri/i965_drv_video.so
-rw-r--r-- 1 root root 35102696 Apr 21 08:50 
/usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

Using the free driver with

  LIBVA_DRIVER_NAME=i965 mpv foo.mkv

gives no error, whereas using the non-free driver with

  LIBVA_DRIVER_NAME=iHD mpv foo.mkv

leads to the above error.
