Thanks a lot,

 It started working on QT player after adding "output-format=sample access-unit=true"

You will probably have to use h264parse output-format=sample access-unit=true in 
both cases, as mov does not really have a taste for bytestream NAL units (and 
would also be missing codec-data and corresponding track metadata), and QT 
player even less.

Using a recent mp4mux/qtmux (as suggested) would likely also make the necessity 
of the above clearer (by means of caps).
