Raspberry PI and Gstreamer

[Arnaud Loonstra]

It can be tricky getting a newer gstreamer compiled. I have some 
compiled debs for raspbian but they are not full feature complete

see: 
https://github.com/sphaero/GentleValleyStream/blob/master/README.textile
for instructions.

basically it's adding this repo:
deb http://lola.z25.org/~arnaud/debian zix25/

I can't guarentee this repo remains available.

Rg,

Arnaud
