Is there a supported way to query whether the capture of the > frame is finished, and return immedietly if it isn't? I'd suggest to use a newer bttv driver. The current ones support read() capture, and you can also use select() the usual way to wait for data. non-blocking read() works too. And, no, these features will never be backported to the 0.7.x driver because the switch from 0.7.x to 0.8.x was basically a rewrite of the driver core ...
