The format is MPEG-4, not DivX

Please don't spread this DivX nonsense on a public website. You obviously either don't understand basic terms (the difference between software and specification, or codec and format), or you're intentionally lying because of the massive ubiquity of the "DivX myth", which is irresponsible.

The compression you're using is called MPEG-4 ASP (MPEG-4 is a standard developed by MPEG) and the codec (i.e. software) you're using for converting it to this format is FFmpeg (libavcodec) MPEG-4. It has absolutely nothing to do with DivX, which is nothing else than a brand name of a commercial closed-source MPEG-4 codec (a piece of software, not a format) that you don't use.

XviD is not a format either, XviD is a name of yet another MPEG-4 codec, which is open-source (FFmpeg/libavcodec is open-source, too). XviD is a piece of software, it also encodes and decodes MPEG-4 ASP video, just like all other MPEG-4 ASP codecs.
