Investigation

I tried to build the previous version of PyAV 12.0.0 with the same toolchain to ensure that this is not connected to a recent GCC upgrade (or changed libraries). It built successfully.

Reproduction

  1. unpack the source archive
  2. run python setup.py build_ext

Versions

Research

I have done the following:

WyattBlue commented 1 month ago

Are you using ffmpeg7, the 12 series still needs ffmpeg 6 or ffmpeg 5

christophfink commented 1 month ago

No, it’s ffmpeg 6.1.1

(edit: but I see that ffmpeg 7 is in the staging repositories for Arch, so this will, indeed, be an issue over here in a matter of days or weeks)

If this fix is required on the 12.x series it's a shame you prematurely dropped Python 3.8..

WyattBlue commented 1 month ago

@jlaine Not an issue if you make separate branches

WyattBlue commented 1 month ago

This isn't worth making a new release over. Debian distros still use gcc 12, Mac and Windows are unaffected, the AUR people will apply a patch. Plus each release takes an ungodly amount of space on PyPI.

christophfink commented 1 month ago

the AUR people will apply a patch I did already: https://aur.archlinux.org/packages/python-av
