DESCRIPTION: Allow access to frames of a video through the ffmpeg library. No intermediate files are stored to disc. Everything resides in memory. FUNCTIONS: + open USAGE: INSTALLING FFMPEG: The api for ffmpeg keeps changing and this is quite frustrating. Rather than use the most recent ffmpeg which broke too many things on ubuntu. I changed the code to work with the recent ubuntu's libav*-dev packaged libs (version 7.3). apt-get install libavcodec-dev libavdevice-dev libavfilter-dev \ libavformat-dev libavutil-dev libpostproc-dev libswscale-dev
