[gst-devel] gstreamer freebox multiroom

[Julien Isorce]

Hi,

I was testing in a virtual machine (kubuntu on virtual box), because
"rtspsrc" seems to be not ready yet on win32.
And it seems that xvimagesink is not available in a VM (I am not sure but I
could  not have it), that's why I tried with ximagesink.

Thx for explanations.

Sincerely
