Updated 10 Aug 2017

MATLAB wrapper for FFMPEG that implements a VideoReader-like interface
Constructor
vr = VideoReaderFFMPEG('test.mp4');
Additional arguments:
tempFolder - path to save the temporary image files to (optional, defaults to ./)
FFMPEGpath - path to the ffmpeg and ffprobe binaries (optional, defaults to /usr/local/bin on osx/unix and C:\Program Files\ffmpeg\bin on windows)
imageFormat - image file format used to temporarily store frames (optional, defauts to tif)
Properties: Width, Height, NumberOfFrames, FrameRate, Channels
Methods:
- read() with single frames or a range of frames [startFrame endFrame], e.g. vr.read([100 200]) reads frames 100 to 200, returns them as [WIDTH x HEIGHT x CHANNELS x NFRAMES] matrix
- clean() deletes all temporary image files (automatically called upon object deletion)
Usage
vr = VideoReaderFFMPEG('test.mp4') % open video file
frame10 = vr.read(10) % read frame 10
frames100to200 = vr.read([100 200]) % read frames 100 to 200
vr.clean() % delete temporary image files after you're done

- uses ffprobe to get meta data
- uses ffmpeg to export video frames as images which are loaded using matlab's imread()
- tested using ffmpeg v2.5 and v2.6
