Ask HN: Any tools to encode mp4 to stream of frames?
I don't understand video encoding/decoding algorithms. What I want is to process a video stream and parse each frame individually, either as an image or as a matrix of rgba values. Anything out there that can help me with that?

If you're looking for a library to do this programmatically, try imageio (Python) or OpenCV's VideoCapture (C/C++/Python/Java). I recommend imageio - very easy to deploy, compared to OpenCV. Don't know about other languages.
Here is one way to just extract the frames:
ffmpeg -i in.avi -q:v 0 imagename_%04d.jpg
ImageMagick http://www.imagemagick.org/script/index.php
Google h264 to raw. Yuv format is what you describe
