The possible reason is media-driver for gen11 (ice lake) lacks the capability query support for VAProfileHEVCMain422_10. With [1] applied in driver, the encoding for yuyv422 works well for me, for both intra and inter frames. Ps. In case you may be interested, I prepared several patches [2] for 4:2:2/4:4: 8/10 bit encoding. They works for me with correct outputs. And the reason for not upstreaming is: 1. 444 pixel format not ready; 2. recon surface of Y210 or 444 (AYUV and Y410 in media-driver) depends on the surface hint [3] in libva and corresponding code in media-driver to resize the recon surface which is not upstreamed yet.
