Current implemantion for autoratation does not support flip.
That is, if the matrix contains flip info, the API get_rotation
only reflects partial information. This change is for adding
support for hflip (vflip can be achieved by rotation+hflip).

Fix #6945
Exif extension has 'Orientaion' field for image flip and rotation.
This change is to add the first frame's exif into stream so that
autorotation would use the info to adjust the frames.
