Looking through the source, I didn't see any code that responds to device orientation so this may not be handled at all.
Handling rotations DURING recording may be problematic, but before a recording begins, we should probably ensure that we begin in the correct orientation.
I believe any transforms applied to the video are hard coded (am I wrong here?), so we may just need to check the interface orientation when just before we start recording and update the transforms.
Yeah I totally punted on orientation stuff since it wasn't clear what the best approach was..
landscape would be great to have
