Dear maintainer,

python-av fails its autopkgtests with ffmpeg 8.1 on arm64:

for details.

Test issues with ffmpeg 8.1 seem to be fixed upstream by
https://github.com/PyAV-Org/PyAV/commit/57d8f4d7215a7b7cc7d01415613fc6aa2831a8d3
and https://github.com/PyAV-Org/PyAV/commit/900e39b9f0f7df33c3ea192b6dc13736e0b1561c
