Title: Added displaymatrix value and display rotation

Hi, we are using streamio-fffmpeg to convert and rotate some videos, but found some issues do to the rotation not been right when the media comes from a mobil device and is taken with the front camera, but also found the displaymatrix meta data has the right rotation information, therefore have added that information into the display_rotation variable so we can used on our code. Hope it help someone else.
