Error building from source on Debian stable

[lscorcia]

Hi, I am having issues when building from source PyAV.
Environment: Debian 12 stable (bookworm) in an x64 VM, Python 3.13.1, ffmpeg and supporting libs from distro packages (7:5.1.6-0+deb12u1).

The command I am using is the basic: $ pip install av==14.0.1 --no-binary :all:.

Logs are quite long:

• logs for v13.1.0: pyav-13.1.0.log
• logs for current release 14.0.1: pyav-14.0.1.log

Version 13.0.0 builds correctly (but Home Assistant needs 13.1.0).

Unfortunately I need to build from source and cannot use the binaries (I discovered those errors because I am actually compiling for a different architecture, but the error is the same even on a x64 VM).

Any idea?
