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.
