[Octave-bug-tracker] [bug #57020] [octave-forge] (video): missing VideoWriter

[Avinoam Kalma]

Follow-up Comment #5, bug #57020 (project octave):

After last additions to Video pakage
(http://hg.code.sf.net/p/octave/video/rev/c4746720f185,
http://hg.code.sf.net/p/octave/video/rev/22ede10d0776),
things looks much better (Thanks Andy!)

The commands:


 demo VideoWriter 


and

 demo Videoreader



work 
(need a change in VideoReader.m: change the line
fn = "/tmp/sombrero.mp4";
to
fn = fullfile (tempdir(), "sombrero.mp4");
as in VideoWriter).

My own demos also work:


vid = VideoReader('vid.mp4');
cnt = 0;
while (hasFrame(vid))
  cnt = cnt + 1;
  I = readFrame(vid);
  imwrite (I, sprintf ('%05d.png', cnt));
end



folder = 'C:\Octave\Video';
vid = VideoWriter('demo.avi');
open(vid);

Images = dir (fullfile (folder, '*.png'));
for i=1:numel(Images)
  file = fullfile (folder, Images(i).name);
  I = imread (file);
  writeVideo(vid, I);
end

close(vid)
