Original question:

AM69A: 8-bit or 10-bit encode with H.264 and H.265

AM69A: H.265 encoder profile support for 10 bits / 4:2:2

Part Number: AM69A
Other Parts Discussed in Thread: AM69

Hi,

I saw the question at e2e-link with the same question I have but there was no answer.

I see in the user manual that the AM92 only support the Main and Main still profile for the H.265 encoder.
Is there no support for Main 10 / Main 10 4:2:2 profile?
Is this a hardware limitation or a software issue?

As the internal video processing in the processor is 12-bit I think it is strange if the encoder is not supporting this.

Actually I'm comparing the H.265 encoder of the AM69 processor with the one offered in the AMD fpga VCU. I know this encoder is good and I'm investigating if this processor would be an alternative.
My requirements are 4K60 10 bit 4:2:2 (Main 10 4:2:2 profile).

Regards,

Robert

    Hello Robert,

    10-bit is not supported, the h/w can only support 8-bit input/output. Additionally, in the TRM, it would specify Main 10 profile if supported. YUV422 is supported but the VPU only processes YUV420 internally so the 422 input would be down-sampled to YUV420 to for compression.

    Thank you,
