Whilst the 'tapt' atom is optional, if included all three of its
subatoms are required according to qtff 2012-08-14.
This patch addresses the missing 'prof' atom. Please note that its value
is the same as the 'clef' atom. This is because currently ffmpeg does
not support the notion of a "clean aperture" so both figures are derived
solely from the pixel aspect ratio and pixel width and height.
Strictly speaking both 'clef' and 'prof' should allow for non integer
values, but that is for another day.....
