libgstallocators-1.0.so.0: cannot open shared object file

[Fabio Cecamore]

Hi Tim,
thanks for your time.

Adding the path to /etc/ld.so.conf finally it worked!
But now its behaviour is strange (this is with the latest 1.1.1):
[BEGIN]

[END]

But if I launch the SAME command in the SAME time in an other VM (with 
0.10 version) it works:
[BEGIN]
root at debianVM:~# gst-launch rtspsrc 
location=rtsp://192.168.0.253/ch0_0.h264 ! application/x-rtp,media=video

There is no problem of firewall, I'm sure.
Is it a bug of this new version ?

About this:

Is likely to be the original live lagging sometimes.. I'll try to use 
sync=false when I'll fix the above problem.
