Comment:
There is a matrix in the track to rotate -90 degrees (counterclockwise),
and a matrix in movie header to rotate -180 degrees. The second one is
applied after the first one, so it's -270 degrees, which is the same as 90
degrees.
VLC failed to handle the second matrix, FFmpeg does which the
specification required.
