Donnacha: What you are suggesting is possible, sort of. It cannot be done using just 1 stream, though. (AFAIK. Someone please correct me if I am wrong.) You'll need to open 2 streams, 1 for video and 1 for audio. After your 20 second delay has occurred, then you can stop recording the video stream. If you are clever with your naming strategy, then identifying the streams as being related should be a snap.
