[Live-devel] Misordered frames with synchronized rtp source

[Ivan Roubíček]

Hi,

I have problem with misordered frames from when fSubsession.rtpSource()->hasBeenSynchronizedUsingRTCP() is true. How is that possible? Is it bug or should I reorder frames myself again? My console output looks like this:

As you can see every second frame is misordered so when I play video I see flashbacks a lot. If I save each frame to the file and then I play them ordered correctly video is playing without any problem. I've even tried to increase packet reordering treshold time from 0.2 to 10 seconds but without any success.

 

I have last version of live555 and I'm using camera BOSCH NBC-265-P.

 

Thank you for any help.

Best regards Ivan
