GStreamer and Rasperry PI

[pauly24]

Thanks, it's almost working now...
I'm still getting an error when I try and play a h264 file.

First error is about the GLib, I was getting this before I tried to install
the plugin, although videotestsrc would still work fine and display on my
screen, I have no idea what these ones are about?

Second and more importantly I've gotten

No decoder available for type 'video/x-h264
yet gst-inspect shows
openmax:  omxh264dec: OpenMAX H.264 Video Decoder
openmax:  omxmpeg4videodec: OpenMAX MPEG4 Video Decoder

so they are installed.
