If I was to do the same, I'd look around V4L2 API. If covers things like
video encoders/decoders etc. The only problem is that the particular
area you are interested in is not well defined yet:

http://linuxtv.org/downloads/v4l-dvb-apis/ch04s05.html

This means that people usually extend the API in their own way, staying
within the framework itself, obviously.

Maybe you could ask about this on the linux-media mailing list?

Good luck!
