I fully messed up my 13.04 installation by trying to verify that ... :-((
I tried to avoid ldconfig (due a library conflict leading to a memory 
error message of gst-inspect) by removing the default gst packages, that 
was a very very stupid idea ...

So the good side of that being that Ubuntu 13.10 is bundled with gst 
1.2.0 { and that I had to clean my comp :-) }
The bad side of it being that I cannot use xvimage anymore  ...
I get
/fred at Paris:~/Downloads$ gst-launch-1.0 playbin 
uri=file:///home/fred/Downloads/sample_iPod.m4v //
//Setting pipeline to PAUSED ...//
//Pipeline is PREROLLING ...//
//Redistribute latency...//
//X Error of failed request:  BadMatch (invalid parameter attributes)//
//  Major opcode of failed request:  149 (XVideo)//
//  Minor opcode of failed request:  13 ()//
//  Serial number of failed request:  31//
//  Current serial number in output stream:  34//
/
Same if I try to display my webcam :-(((

However I works fine with the 0.1 version ...

If anybody already faced that problem, a hint would be very welcome.

Thanks that sounds good however I cannot test until I solved the issue 
above as the a 1.0 element only.
BTW, is it possible to change the location through the command line or 
it must be done programmatically ?


Thanks,
Frederic
