# 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:

```matlab

ffmpegOpenVideo('video.mov');

imshow(ffmpegGetFrame());

ffmpegNextFrame();

imshow(ffmpegGetFrame());

ffmpegCloseVideo();

```

An example of writing video frames to disk:

```matlab

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.
