LIVE555-based applications use a single-threaded event loop (i.e., using events
- rather than threads - for concurrency). See

I did it and unfortunately there is no improvement. I've also checked
other receivers (mplayer, ffplay) and behavior is very similar.

We noticed that a VLC release around two(?) years ago changed
the way audio/video is prioritised/synced which primarily affects
streaming (i.e. not file playout) in the way you described.
Previously audio had always played smoothly.
This more than likely has nothing to do with live555. You can v

That is totally correct. Different media streams have different RTP timestamps
(perhaps with different timestamp frequencies, as is the case here), and the
