When I turn on the logs with level-4, I do get the packet back!!! - so it could be timing issue, I suspect.</div><div>c. The bin1 returns say 200 or so packets and the app receives an EOS message from it! - why is that?</div> <div>3. Does appsink return packets as and when it receives them or does it wait to preroll?</div><div><br></div><div>Please help me understand the situation better. I've hit a roadblock!
