[Pkg-octave-devel] video pkg fails to compile

[Saso Musevic]

Sorry about my previous out-of-scope mail, here goes the problem and
solution.

Tried to install octave package from octave-forge: video-1.0.1  (file:
video-1.0.1
.tar.gz<http://downloads.sourceforge.net/octave/video-1.0.1.tar.gz?download>
)

octave:31> pkg install video-1.0.1.tar.gz

Looking at the compile error you can see, it is trivial to fix it. I just
fixed a few lines (changed some parameters  to pointers) in  AVHandler.cc
(from video-1.0.1 package) and compile succeeded. Haven't tried if all
package functions work (in Octave), but so far it looks ok.
If you need exact versions of Octave/ffmpeg/libavformat etc.. and/or the fix
let me know.
