 All of these can't be supported by vaapi too, and QVBR has been enabled
 and the patch is under-review: https://patchwork.ffmpeg.org/patch/11222/

 If we just talk about Linux and compare ffmpeg-vaapi with ffmpeg-qsv, I
 like ffmepg-vaapi's decoder too. But for encoding, qsv can support more
 features, just like Look_ahead, ICQ which can provide better quality, and
 MFE can provides better performance.
