rtsp camera to UDP TS multicast packet has been to late
Posted: 13 May 2015 08:50
When running this on vlc 2.2.1
i get video output on the multicast as it should. but if i bump up the bitrate from the camera (over 8Mbit) i get massive frame drops. (when playing the rtsp stream direct in vlc i get no frame drops. the CPU is strong enough
debug messages at 5Mbit stream:
i still get packet has been sent to late but no frame drop if i keep it below 7.5Mbit.
note that if i run this on ubuntu 15.01 i get worse results and have to limit it to 5Mbit to avoid frame drop
is there any solution to this? it seems that live555 is not handling the size of the frames from the camera. (have no idea how to reduce that)
