I suspect this is from the display matrix in the mvhd atom. In this file, it is
(I think - manually parsing it from a hex dump, I haven't written code for
this):

[ 2   0   0 ]
[ 0   2   0 ]
[ 0   0   1 ]

Also, even if we did parse this, we don't actually have any mechanism in
gstreamer to expose an arbitrary transformation matrix to downstream.
