Due to the alsa detection code that I've added at libv4l2util (at v4l2-utils) during the weekend, I decided to add alsa support also on xawtv3, basically to provide a real usecase example. Of course, for it to work, it needs the very latest v4l2-utils version from the git tree. I've basically added there the code that Devin wrote for tvtime, with a few small fixes and with the audio device auto-detection. With this patch, xawtv will now get the alsa device associated with a video device node (if any), and start streaming from it, on a separate thread. As the code is the same as the one at tvtime, it should work at the same devices that are supported there. I tested it only on two em28xx devices: - HVR-950; - WinTV USB-2. It worked with HVR-950, but it didn't work with WinTV USB-2. It seems that snd-usb-audio do something different to set the framerate, that the alsa-stream code doesn't recognize. While I didn't test, I think it probably won't work with saa7134, as the code seems to hardcode the frame rate to 48 kHz, but saa7134 supports only 32 kHz. It would be good to add an option to disable this behavior and to allow manually select the alsa out device, so please send us patches ;) Anyway, patches fixing it and more tests are welcome.
