Here is the last 300 lines of the buildlog
ucbuildlog.txt

The useflags I have enabled are as follows

I get this message at the beginning of the build, when applying patches
You need to expose "av_stream_get_first_dts" in ffmpeg via user patch

I think this patch might fix the issue. I will test it and report here.

I have applied the patch patch to ffmpeg by placing it on /etc/portage/patches and running ebuild ffmpeg-6.0.1-r2.ebuild clean prepare and then emerging ffmpeg.

I emerged ungoogled-chromium, and it was successful.

I am new to this, how do I submit a pull request to include this patch in future ffmpeg releases? Should I submit this pull-request to the ffmpeg ebuild repo or here?

Short answer: no. It is a known issue. In a nutshell Gentoo neither provides support for system-ffmpeg in Chromium nor patches ffmpeg to make it compatible. I decided to keep support of system-ffmpeg in ungoogled-chromium.

PS: it would be great if you searched existing issues first
