[Xorg-driver-geode] Xv PutImage crash

[Cui, Hunk]

Hi, Daniel,
	I have installed totem-mozilla" in ubuntu (I think it uses the firefox engine as you said, is it right?), used Chrome browser, when I broadcast the ogg video, then the terminal print some info: TotemEmbeded-Message: totem_embedded_set_error: 'Could not open location; you might not have permission to open the file.' So it can not broadcast the video. :(
	I am sure it is "Totem Browser Plugin 2.30.2" (using GStreamer 0.10.28). It will link to /usr/lib/mozilla/plugins/libtotem-cone-plugin.so.
	So I hope you can tell me how to use totem's mozilla plugin in browser and the install steps? (more detail) 
	For me, it is very urgent.

Thanks,
Hunk Cui
