portrait mjpeg video rendering

v 0.5 works flawlessly on my BDPS-570
however portrait mjpeg recordings (canon G7) are played in landscape mode (90° rotation)
is it possible to adjust the profile to (1) automaticly detect the orientation of dthese videofiles and (2) to render these particular files in a protrait mode

mjpeg clips are transcoded, so if it's possible to achieve that with FFMPEG then Serviio code would need changing. It wouldn't be a profile mod.
