Hi Tim,
I've recompiled the gst-plugins-ugly and all others plugins related, like plugins-ugly, plugins-bad, plugins-base, plugins-good , gst-ffmpeg, ffmpeg and gstreamer. I'm certain that the integration is complete by inserting some printfs in the code and making sure that it is print on the stdout.
I still don't know what to do =(.

Just as a note, the x264enc plugin code has some special handling here
and there depending on the x264 version compiled against. It assumes
that the x264 version used at runtime is actually the one it was
compiled against as well at the moment. This can lead to weird things
happening when you upgrade/downgrade libx264 to a different version than
the plugin was compiled against.
So when you upgrade/downgrade libx264, you definitely need to recompile
gst-plugins-ugly.
(There may still be a bug of course..)
Cheers
