proxysink/src timing/lag/stutter issue.

I may be implementing proxysink/src incorrectly but i am having issues. It seems as though proxysrc is either queuing up buffers or there is a timestamping issue. Any help would be greatly appreciated.

Fortunately today after doing some tests I have found why it does not work and how to fix it. When pipeline goes to PLAYING state, it updates its base time to current time. To fix this, you have to get base time from one pipeline and set it as base time for second one. I do this just after setting state of 2nd one to PLAYING. You also should remove lines which change start time, this produces some strange results.

I think this is entirely down to the "media-pipeline" created by rtspserver being out of sync. Looking into this now.

Hi Daniel, Chris,
Have you seen this bug report about this problem? This specific comment has instructions that should make it work: https://bugzilla.gnome.org/show_bug.cgi?id=794893#c2 There are other issues related to the RTSP server that are not resolved yet. Perhaps we should discuss details on the bug report?

For the same using rtsp-server with proxysink->proxysrc, I am facing error as
