RE : Re: lag/freeze in streaming H264 or RAW from udpsrc on Windows

Hi Sébastian,

In fact with client pipeline in Windows, the playing of the stream is too fast. The framerate is not take account. 

I dont understand why i need to disable the synchronization because it works perferctly with the same pipeline in Ubuntu. 

I think there is a strange behaviour about the timestamping or synchronization troubles in gstreamer in Windows.

The cpu rate of the client is low, the video is often blocked as if the timestamping is corrupted.

Also in reading the forum, it seems that this problem is known but never really resolved.

What do you mean with freeze and lag, what exactly happens? You should
in any case add a queue after the udpsrc (or an rtpjitterbuffer), and
maybe also want to increase the buffer-size property on udpsrc.

You should do that any way :) sync=false in these cases is not a
solution for anything.
