Video sync via GstClock

[Andreas Rödig]

Hi Marc,

ok, more details:

I have one or many videos. All of this videos have the same length. 
Every video runs on another pc.

Then i start all of this videos at the same time. But sometimes they 
will not be at the same frame.

So, my idea was: I have one master or time provider and all other 
pc/gstreamer pipelines have to sync to the same frame position as the 
master pc.

At the moment i try to transfer the position of on master/gstreamer 
pipeline via socket to another gstreamer application.

With gst_clock_set_calibration i can set the slave gstreamer clock to 
forward to the received master position. But not backwards.


Thanks,
Andreas Rödig
