Looks like configure.ac wasnt updated to release version number

AC_INIT([Octave-Forge video package], [2.0.2])

Compiling hg sources I noticed that package strings still use "2.0.2" (-DPACKAGE_VERSION=\"2.0.2\" and
-DPACKAGE_STRING=\"Octave-Forge\ video\ package\ 2.0.2\")
even though the package itself is 2.1.0.

Yeah, I answered there (and changed to ready for test), the reason for the segfault is, that av_guess_format returns NULL if the container format can't be guessed. Nice catch!

Since it crashes both 2.0.2 (with ffmpeg 4) and 2.1.0 I made a new 
report:

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:

If I copy the demo code, but "misspell" file name as "sombrero,mp4" it will crash 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);

Sorry -- I clicked "Download Snapshot" (which I assumed does the
hg snapshot). If I do "hg pull" I get it working

I do not know anything about docker. Centos Stream is not the same as Centos, it is a kind of "upstream" release of Redhat
Linux (https://www.centos.org/centos-stream/).

Thank you for testing.
You are building the mercurial repo from https://sourceforge.net/p/octave/video/ci/default/tree/ right?

Btw, I was currently removing all CentOS tests because I thought it's dead after Red Hats last escapades.

Can you point me to an docker image, which you think might be good to be tested against?

https://hub.docker.com/_/centos is marked as DEPRECATED

I'm started on backporting the latest cap_ffmpeg_impl.hpp from OpenCVs 4.x branch, see

http://hg.code.sf.net/p/octave/video

currently it compiles and runs on Debian Bullseye (11) with ffmpeg 4.x and Bookworm (12) ffmpeg 5.x.

I'm happy if someone joins for testing/patching.

I encountered this issue when updating ffmpeg in Octave Online. For the time being, there is a "compat-ffmpeg4-devel" RPM package that continues to work with the video package:

https://pkgs.org/search/?q=compat-ffmpeg4-devel

However, I don't know how many more releases compat-ffmpeg4-devel will be available, so migrating to ffmpeg5 is the only long-term solution. There are some other projects using ffmpeg that have migrated; here is one that was having similar compile errors to the video package:

I had a quick look after Avinoam Kalma added me but it looks like the API had some big changes from ffmpeg 4.4 to 5.0 and libav should also be supported (or are we willing to drop support for libav?).

Tl;DR: No, I'm currently not working on this and it looks like a big change which I can't do the next 3 months.

The video package fails to build against FFmpeg 5.0 (see Bug#1004770, filed against the Debian package octave-video).

Is someone working to fix this?
