VAProfile is not supported (12) With MPEG2 playback

[heitbaum]

This is the error being logged using 2.9.0 and 2.10.0.pre2 playing an MPEG2 stream. Any reason this is occurring and the VAAPI is not HW decoding, given that MPEG2 is listed as supported.

seems a media-driver issue, create config failed. could you help to share more details, such as command line?

Hi @XinfengZhang - it has been happening for a long time in the Kodi Leia/Matrix time. I have done some investigation and brought all the Intel code up to current in The Matrix HEAD. These are the logs from cvh . http://ix.io/2HpU, these are the logs from me. http://ix.io/2HpA

My uneducated guess is that Kodi is calling ffmpeg with a profile=12... might be wrong (12 in the vadumpcaps is JPEG ???)

Here is the bug I raised on LibreELEC - https://github.com/LibreELEC/LibreELEC.tv/issues/4732

Here is the full background and investigation I have done so far - https://forum.libreelec.tv/thread/23090-intel-vaapi-and-hardware-mpeg2video-decoding/?postID=147266#post147266
