AVC/H.264 10-bit decode

[Stubbly3343]

The hardware encoding and decoding capabilities of the Intel Arc discrete GPU are generally quite good, but it notably lacks support for AVC/H.264 10-bit. I suspect this isn’t due to a hardware limitation but rather to firmware, driver, or software issues. However, since I’m not an expert, I’d like to ask whether it’s feasible to add AVC/H.264 10-bit codec support (particularly for decoding) to the Intel Arc discrete GPU? Certain camcorders and cameras use this format, so adding this capability would greatly facilitate video editing and playback. Thank you very much.

Media Capabilities Supported by Intel Hardware

H.264 (AVC) 10-bit decoding is not accelerated by any graphics hardware (even Nvidia or AMD). If CPU processing is too slow for playback, I'd recommend transcoding the videos to H.265 (HEVC) or selecting this format directly on the camera for recording if possible.

Not true.

This is why some creators find it reassuring. Given that hardware encoding and decoding are areas Intel emphasizes, I hope Intel can catch up with Team Green.

Yes, you're right.

Sorry, I didn't know that. Since the H.264 codec is older, I wouldn't have expected anyone (other than Apple) to bother supporting it in hardware at 10-bit. Therefore, I never checked the Nvidia Blackwell series' capabilities in this regard. Nvidia has apparently not yet updated the official NVDEC table.
