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? http://vger.kernel.org/vger-lists.html#linux-media Good luck!
