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.
