For example, if the jpeg contains exif information
and the rotation direction is included in the exif,
the displaymatrix will be set on the side_data of the frame when decoding.
However, when ffplay is used to play the image,
only the side data in the stream will be determined.
It does not check whether the frame also contains rotation information,
causing it to play in the wrong direction
