do you set the format correctly, e.g.:
https://github.com/FernetMenta/kodi-agile/blob/master/xbmc/cores/VideoPlayer/DVDCodecs/Video/VAAPI.cpp#L2697
to create the surfaces?

afterwards we just do drm / egl interop, via:
https://github.com/FernetMenta/kodi-agile/blob/master/xbmc/cores/VideoPlayer/DVDCodecs/Video/VAAPI.cpp#L1374

You need ffmpeg 3.2.

If you use vaPutSurface it will end up as RGBA32 or something, which is why
we use the above way.

Best regards
Peter
