The caps that are being used are actually in the (warning) messages below,
and it shows the caps in question do not have much to show for themselves.
In particular, width and height are missing, which qtmux (and so would probably 
others) does not appreciate.  It would also at least be necessary to run 
rtph264depay byte-stream=FALSE, since bytestream format is not meant to go into 
mp4 container.
