If you could take at look at those and than start implementing your own API just keeping them in mind, you should have a first version that will be useful. After this is working, I guess people who are using the driver will let you know what else they need. After that and maybe adding some more drivers for other hardware, like the kfir (I'll crosspost this mail to their mailing list). You can also ask the software people on the libmpeg2-devel list, whose programs will probably replay the recordings, for input (also cross posted). Just remember not to be too hardware specific and if you see limitations of your own hardware which may not be present on others, keep the API open for that. I guess as soon as there is an API people will tell you what they think. In my experience, you usually don't get much response if you keep the discussion too theoretical. Just my 0.02 Euros.
