Python has standard library modules to aid with that.

For data packets, I wrote a script for a client once which processed video 
files recorded on GoPro cameras and extracted the instrumentation streams 
containing GPS and accelerometer data.

I used the ffprobe command (part of the FFmpeg suite) to locate the 
positions and PTS values for the packets, then decoded them with the 
struct <https://docs.python.org/3/library/struct.html> module.

Details on the format (a bit incomplete and out of date, last I checked):
