Some stuff to try:

 * Encode just video or audio to see which is causing problems
 * Add max-bframes=0 to xvidenc
 * If the FOURCC isn't being set you could add it manually

I'm not 100% sure about the FOURCC thing but you might be able to do
something along the lines of ... ! 'video/x-xvid,
format=(fourcc)XVID' ! ... just after the xvidenc element.

Good luck and if you get it working I'll add the preset to Arista.
