ffmpeg-matlab's Introduction

FFmpeg/libav bindings for Matlab

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.
