Adds divx/xvid encoders. divx encoder is based on divx4linux (commercial, closed-source)
Original commit message from CVS: Adds divx/xvid encoders. * divx encoder is based on divx4linux (commercial, closed-source) * xvid encoder is based on xvidcore (http://www.xvid.org/, GPL - Christian? ;) ) Both use a GstCaps that doesn't conform with what we currently use, I might fix that later on or so. For now, it doesn't matter, it's just a test. We're also missing corresponding decoders (ffmpeg can decoded this too, but that's not the point), these might come later too.
