Video frames distorted in Live555 Proxy Server - how to fix

Hello Ross,

In my use case, I have an IP camera as rtsp stream source and I have to
proxy the stream. I am using Live555 proxy server executable and I found
that there is absolutely no latency. This is indeed great!

However, the proxied stream is sometimes distorted as viewed by a RTSP
client application (vlc in my case), even when the rtsp stream direct from
the camera is playing quite well in the same vlc player.

To be specific, when I observe Camera OSD in the proxied stream, I find
that the time as shown in the video frames is going one second backward and
then again forward, and then ultimately catching up with real time. And,
the video frames get distorted during these time slots.
For example, in OSD, the time is shown in the following sequence:

06:37:40 -> 06:37:41 -> 06:37:40 -> 06:37:42 -> 06:37:43

and this occurs repeatedly.

Please help me find out what I am missing, or is there anything I can do to
fix this.
