FFmpeg does not currently support the Quicktime CLEF (Track Clean
Aperture Dimensions) and TAPT (Track Aperture Mode Dimensions) atoms.
These atoms are necessary for detecting the correct dimensions for
some videos, since they take precedence in Quicktime over the normal
TKHD (track header) width/height and over the track PASP (pixel aspect
The attached patch adds support for these atoms. Sample videos can be
found at https://ffmpeg.org/trac/ffmpeg/ticket/1485.
