Subject: Re: Stateless Encoding uAPI Discussion and Proposal

Hi folks,

Just a quick message on this thread to let you know that we have just published
the code for the H.264 encoding extension to cedrus for the V3/V3s/S3.

You can find more details in the dedicated blog post:
- https://bootlin.com/blog/open-source-linux-kernel-support-for-the-allwinner-v3-v3s-s3-h-264-video-encoder/

And the code is at:
- https://github.com/bootlin/linux/tree/cedrus/h264-encoding
- https://github.com/bootlin/v4l2-cedrus-enc-test

As announced this doesn't really help advance our uAPI discussion here since
there is no rate-control yet and the stateful controls are reused for
controlling the encoding features (including things like GOP).

Cheers,

Paul
