**Summary of the bug:**
See
https://github.com/streamlink/streamlink/issues/6410#issuecomment-2603369602
The Streamlink project implements a DASH client in Python and uses FFmpeg
to remux the resulting video/audio streams into its output.
In the linked thread above, a user ran into an issue with FFmpeg `n7.1`
that doesn't occur on `n7.0` or recent builds from `master`.
After running `git bisect start 'n7.1' 'n7.0.2'` and rebuilding FFmpeg, I
found commit a696b288861a09403e316f4eb33bbc7cb6c03e5c to be the culprit.
And after checking the master branch, I found that commit
5813e5aa344b8c03c83bf62e729be0f447944ed1 already fixed the regression
introduced by the other commit.
However, the fix was never backported to the `release/7.1` branch:
https://git.ffmpeg.org/gitweb/ffmpeg.git/history/refs/heads/release/7.1:/libavformat/hevc.c
I'm therefore asking for a quick backport. Thank you!
Also, since I'm not aware, what's the patch release policy of FFmpeg? Will
there be another patch release (`n7.0.3`), or do we have to wait for
`n7.2`/`n8.0` to be released? Thanks.
