Public bug reported:

https://gitlab.freedesktop.org/mesa/mesa/-/issues/11533

For distribution packagers, to resolve this you can do the following:

Revert b0d6e58d (not recommended)
Apply !30255 (merged) to your Mesa package on top of v24.1.4 (recommended)

Either of those will resolve this issue without requiring patching
packages, though patching ffmpeg packages is also recommended. For that,
you should backport this and this patch from upstream ffmpeg source.
Both will apply cleanly to ffmpeg 6.x and ffmpeg 7.x source, the second
patch patch however will not apply cleanly to 4.4.x source (here is a
backport with the conflicts resolved for that). The vendored ffmpeg in
Firefox also needs to be patched, here is the patch for that.
