I'm not sure, video/x-xvid wasn't really removed, there were plenty of places
where it was still in use, gst-inspect-1.0 avdec_mpeg4 was still accepting it,
for example. Now it sounds like we removed it for a reason from everywhere else
(I guess because it's just like mpeg4), then I would suggest to removed it from
the encoder too again.

That should be possible and it was the main solution, did you try it and did it
fail?
