Hello, I'm using the streaming grabbing capture mode from v4l2 (QBUF, DQBUF, etc) on a 'bad' video signal with noise and broken vsyncs (caused by fast switching of out-of-sync input signals). Is there a way to tell a frame is 100% successfully grabbed, from top to bottom ? Right now I solved this by initializing the buffer with a known value, and looking for pixels of this value after the grab. If they're still there, the grab probably failed. Is there a nicer way to check for this ? Regards, /Ico
