+            atom_trak_get_timescale (qtpad->trak), GST_SECOND);

The timescale is not necessarily 1 sample (i.e. 1 audio sample, 1 video frame,
etc: for video it usually is a 100th of a frame) but can be almost anything.

I think this generally makes sense though. While you do this now not only in
prefill mode (please change the commit message), there's not much point in
adding such a small entry.
