Limit size of initial keyframe in one-pass.
Rather than using a default size of 1/2 or 3/2 seconds for the first
frame, use a fraction of the initial buffer level to give the
application some control.
This will likely undergo further refinement as size limits on key
frames are currently under discussion on codec-devel@, but this gives
much better behavior for small buffer sizes as a starting point.
Create a new input parameter to allow specifying
the packed frame stereo 3d format. A default value
of mono will be written in the absence of user
specified input
