ffmpeg crashes playing mpeg4/xvid AVI

[cavemanmike]

Running Jellyfin 10.9.9 directly (not a Docker instance) on Debian 12. Playback works fine except when playing older Divx/Xvid AVIs. ffmpeg crashes with the following logged:

Googling error 234 for ffmpeg doesn't get me anywhere. I know the issue may be related to the MPEG4 stream, but I'm stumped.

Note that I only have jellyfin-ffmpeg7 installed, I don't have the plain ffmpeg installed.
