[Octave-bug-tracker] [bug #61978] [octave forge] (video) Failure to build against FFmpeg 5.0

[Dmitri A. Sergatskov]

Follow-up Comment #11, bug #61978 (project octave):

May be the crash should be a separate bug report....
Not 100% sure if this is octave issue or video package issue.

In any case here is a backtrace:

Thread 6 "QThread" received signal SIGSEGV, Segmentation fault.
