According to Wikipedia, AV1 main, high and pro support 4:0:0 sampling (in 8, 10 or 12 bit, the latter being the professional profile only). However I don’t see this format supported by NVEnc (_NV_ENC_BUFFER_FORMAT).
Did I miss something or does NVEnc just not support it?
Hi @RobinsonUK, nice to read from you again.
The Video Codec SDK Application notes state which profiles are supported by our GPUs and are exposed by the SDK.
If you check out AV1 you will see
AV1 main profile: Capability to encode YUV 4:2:0 8-bit and 10-bit content up to 8192 × 8192 resolution and generate a AV1 bit stream.
So no, 4:0:0 is not supported right now. And keep in mind that only Ada generation GPUs introduced AV1 encoding.
Thanks!
Hi Markus,
Thanks very much for confirming that. I have bookmarked the notes.
