[Question]: Which profile in H.264 supports AMF_COLOR_BIT_DEPTH_10 ?

[abhay31914]

In HEVC, I successfully set the value of AMF_VIDEO_ENCODER_COLOR_BIT_DEPTH to AMF_COLOR_BIT_DEPTH_10 with the profile set to MAIN_10. Now, I want to configure the same setting for the H.264 encoder.

VCN encoder doesn't support 10-bit for H.264, 10-bit supported for HEVC and AV1.

I will clarify a bit.
No GPU accelerated HW encoder currently supports AVC 10-bit [Aka AVC Hi10p] profile. Not AMF (VCN), not NVENC, not QSV.

Even for HW decoders AVC 10-bit support is... Uncommon to say the least.
(Unexpectedly Nvidia added HW Decode for AVC Hi10p with RTX 5000 series. But only decode, and only they.)

At least it is definitely not something average home TV or smarphone will support.
Unlike HEVC 10-bit which is pretty much widely accepted codec for 10 bit encoded movies. (AV1 is still not very common)
