Comment (by Alexander):

 You can reproduce this problem on a local machine:
 1. Start listening instance of ffmpeg:

 {{{
 ffmpeg -loglevel debug -rtsp_transport tcp -rtsp_flags listen -i
 rtsp://localhost/in/1 -acodec copy -vcodec copy -f null /dev/null
 }}}

 2. Start sending some mp4 file:

 {{{
 ffmpeg -re -i source.mp4 -acodec copy -vcodec copy -f rtsp -muxdelay 0.1
 rtsp://localhost/in/1
 }}}

 You'll get warnings about non monotonically increasing dts on listening
 instance.
