So as the only encoder I found so far ffenc_mpeg4 got two SRC pads.

One is video/mpeg,mpegversion=4 and the other is video/x-divx,divxversion=5.

So according to the ffmpeg FAQ http://ffmpeg.mplayerhq.hu/faq.html#SEC23 there
difference between these two (and divxversion=4) which you can also set on the
ffmpeg level is the FOURCC value.

Having to take this situation into account would make my code quite a bit more
complex as I can no longer iterate on element to create my dictionary between
caps and elements, with caps as the unique value, but have to instead iterate
on caps and at the same time finding back to the original element which had
that caps.

My suggestion is that we do here what we did for qtmux, which is to have one
virtual element for each caps type.
