Feature Request: davs2-10bit

https://github.com/aliofwind/davs2-10bit
I tried to integrate it in my fork but failed. I'm not sure if this is related to the upstream.

Are you sure FFmpeg actually supports that?
Cause there already is davs2, which is also already built here.
That repo seems to be a fork of a fork of the davs2 I'm currently building.

How to view ffmpeg configure log in ffbuild/config.log when using Github Action?

Seem to be possible. https://github.com/xatabhk/FFmpeg-avs2-avs3
But it seems that there is no source code for compiling it, it just mentioned it used this

Yeah.

That repo seems to be a fork of a fork of the davs2 I'm currently building.

Yeah. The original davs2 ONLY supports 8bit videos, and does not support 10bit formats commonly used in 4K HDR videos. I'm not sure if the code here can be used normally, and more tests are required.

That is a fork of FFmpeg, so adding that library here would not do any good, since I only build original upstream FFmpeg.
You'd first need to get those patches upstreamed to FFmpeg.

Also, the only difference of that fork seems to be the addition of a libuavs3e based encoder?

Hope to add AVS2-10bit support

[BtbN]

Again, I won't patch FFmpeg here.
If you need a new feature like that, please first submit it upstream. It is still unclear to me if this doesn't just work.
libdavs2.c in FFmpeg looks like it generally might support 10 bit? Are you sure it doesn't just work already?

Refer to my fork and https://github.com/xatabhk/FFmpeg-avs2-avs3
By the way, can anyone help me find the reason for building a failure? https://github.com/zhengqwe/FFmpeg-Builds/actions/runs/13072737352

You are offering nonfree builds for download, that is a direct violation of the GPL.
Please stop doing that.

Besides, the only apparent difference is you re-enabling vvenc, and said nonfree builds?

And again, I won't carry third party FFmpeg patches here. Get them upstreamed, and I can take a look at the necessary libraries here.
