I have retried with the latest SVN, and the behaviour has changed. When I switch to radio mode, every time I cat /dev/video0 > /tmp/toto, it creates a /tmp/toto file of exactly 12224 bytes. It contains a pack header, a system header and the first I frame. It stops after that. Do you have any idea which changeset might have changed this behaviour ? This may be a hint as to where I must look.
