From what I observed, I think videomixer doesn't work well with videos
with different framerates and different colorspaces. Try adding a
videorate and a colorspace on one (or both) streams before the
videomixer to make your different cameras work. If that doesn't work,
then try also a capsfilter after the videorate and colorspace right
before the videomixer.

I have a PictureInPicture class in python that adds all those elements
before the videomixer if you want to take a look. It gets kind of big,
but that's the only way I was able to mix any two different streams.
