[gst-devel] tcpsink - tcpsrc- gdp problem

[Mattias Barthel]

Hi,

I have also met a similar situation where a pipeline got frozen locally 
in windows.
I also used the tcpserversink/tcpclientsrc combination. And after a 
certain amount of time/frames it froze
for me aswell.
Do anyone recognize this?


Thanks,

Mattias
