I found a workaround: manually install gstreamer-0.1-ffmpeg, then restart Arista.
Similarly, to be able to achieve my transcoding, I add to manually install gstreamer0.10-plugins-bad-multiverse and gstreamer0.10-plugins-ugly-multiverse. Arista detected the missing codecs but the plugin search failed.
So, I think that the problem is in the plugin resolution mechanism.
I encountered the same problem with Ubuntu 9.10.
