Given that a video stream/frame may have only one or both views coded with

AV_STEREO3D_UNSPEC for this purpose.
not to bikeshed the name, but why UNSPEC instead of UNKNOWN?
It's what was used in ch_layout, so i figured I'd use it here too.

The most common case for this is container level signaling of Stereo3D
video
where the specifics are defined at the bitstream level.
