Hi Zhong,

I have not submitted such FFmpeg SVT-AV1 plugin patch to the community, like the similar one for SVT-HEVC, not just because SVT-AV1 is under development and not officially released, but also because the patch is NOT fully functional and many severe blocking issues exist, such as this https://github.com/OpenVisualCloud/SVT-AV1/issues/268  (~50% frames coded by SVT-AV1 fail to get decoded for the pkts generated by it don't fully compliant with AV1 spec and have confliction with the av1_metadata_bsf filter).

And in the SVT-AV1 GitHub, it's an open message that it is not ready: https://github.com/OpenVisualCloud/SVT-AV1/issues/259.

You (or anyone) are welcome to contribute to the SVT-AV1 project, and submit the FFmpeg plugin changes you'd like to make here: https://github.com/OpenVisualCloud/SVT-AV1/tree/master/ffmpeg_plugin, and we will take your commits seriously. But I have not got any code changes made by you in our project GitHub and it seems you haven't made any contribution to the project yet.

To be honest, I felt more than embarrassed that this internal work in progress of ours, which is only half-done, got exported to the real world, which is to get read and judged by all the experts on FFmpeg community.

Please do ignore this review request. It's NOT at least basically working yet. I am going to submit one when it is.
