Hey I have a new project, basically I'm making some PVR software, similar to Tivo. A question has occured though as I was going through the V4L and V4L2 Api specs...
I Have 4 questions, I would be very grateful if any of them were answered:
1. If I have a hardware based MPEG2 encoder in my PVR card, then how do I interact with the device? i.e. Do I just read from it and I get and MPEG2 encoded video stream from it? Do I still only catch frames, but have an extra ioctl() call to encode them??
2. How do I record sound as part of my tv program? As far as I know V4L can only be used to capture video, however sound is an essential part of a tv program. I need to record that too.
3. How do I flip through Television Channels? To access the stuff on channel 40, Fox what would I have to do. How can I switch to reading Channel 39, ESPN?
4. I've read all the documentation that a basic google search brought up. Are there any places where I can find more info?
Thank you VERY, VERY much in advance.
