Check with e.g. wireshark if packets get lost, or if any packet
fragmentation is happening. RTP packets have a sequence number, and
that's supposed to be monotonically increasing by one.


Also make sure that you have large enough kernel-side buffers for the
UDP sockets on both sides, and try increasing them if you didn't do so
yet.
