These bindings use ffmpeg to read videos into Matlab. Just run make and addpath this directory.
Frames are decoded on the fly. The API is tiny and simple:
ffmpegOpenVideo('video.mov');
imshow(ffmpegGetFrame());
ffmpegNextFrame();
imshow(ffmpegGetFrame());
ffmpegCloseVideo();An example of writing video frames to disk:
ffmpegOpenVideo('video.mp4');
frame = 1;
while(not(ffmpegIsFinished()))
imwrite(ffmpegGetFrame(),sprintf('frame-%06d.ppm',frame));
sprintf('frame-%06d.ppm',frame)
frame = ffmpegNextFrame();
end
ffmpegCloseVideo();For the moment only one video can be open at a time.
