Given that a video stream/frame may have only one or both views coded with
the packing information being unavailable, this commit adds a new type value
AV_STEREO3D_UNSPEC for this purpose.
The most common case for this is container level signaling of Stereo3D video
where the specifics are defined at the bitstream level.
So what information does the side data contain then?
Everything but the packing type (AVStereo3DView, AVStereo3DPrimaryEye,
baseline, horizontal_disparity_adjustment, and
horizontal_field_of_view), which is what the vexu and hfov boxes signal.
Don't all these imply the video is stereo?
Yes, but not how the views are packed.
I changed the description locally to "Video is stereoscopic but the
packing is unspecified.", fwiw. 2D should be the only value for monoscopic.
