I am running RealProducer to capture and encode video from an ATI TV Wonder card. Is it possible to change the TV channel from a separate application while RealProducer is still running and has the /dev/video device open? So far everything I've tried gives me the "device or resource busy" error. Currently I kill RealProducer, use v4lctl to change the channel, and then restart RealProducer. Is there a better way to do this? I am streaming TV and want to provide a web interface to change the channel. The current stop/change/start approach works, but it is inconvenient and slow, requiring the player to be restarted. I am running v4l1, as RealProducer says it doesn't support v4l2. I have read that v4l2 supports multiple opens on a device, but is there a (hopefully convenient) way to do it under v4l1? Even a dirty hack is acceptable... ;) I am new to Video4Linux and having a lot of fun with it. Please excuse me if I have missed an obvious solution to this problem. Thanks, Dan Carlson dmcarlsn@xxxxxxxxx
