| Jul 14, 2015 at 22:52 | comment | added | user9444 | I use ffmpeg to stream raw data (sequential rgb int array) to TCP/IP socket and then read the data from a Java process. I process it and then do the same thing in the other direction to create a new movie. I assume you could do the same thing with Mathematica using JLink. I'm not putting this as an answer because there are too many unanswered details. It's just one possible direction. | |

In theory this might (or might not) work: check VLC (in partcular cvlc) documentation on how to send decoded output to a pipe. Create a named pipe (if you're on a Unix-like system), and pipe the output in there. Use Mathematica's BinaryRead or related functions to read frames one by one. Mathematica has no builtin functionality to read from video streams. This is what'd I look into first if I really had to do this, but honestly, it's a long shot.
