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

[Dmitri A. Sergatskov]

Follow-up Comment #9, bug #61978 (project octave):

With new (2.1.0) package I get some excessive chatter:

octave:3> demo VideoWriter
VideoWriter example 1:
 fn = fullfile (tempdir (), "sombrero.mp4");
 w = VideoWriter (fn);
 w.FrameRate = 50;
 open (w);
 z = sombrero ();
 hs = surf (z);
 axis manual
 nframes = 200;
 for ii = 1:nframes
   set (hs, "zdata", z * sin (2*pi*ii/nframes + pi/5));
   drawnow
   writeVideo (w, getframe (gcf));
 endfor
 close (w)
 printf ("Now run 'open %s' to read the video with your default video player
or try 'demo VideoReader'!\n", fn);

Now run 'open /tmp/sombrero.mp4' to read the video with your default video
player or try 'demo VideoReader'!
