[FFmpeg-devel] [PATCH 1/7 v2] avutil/stereo3d add Monoscopic View enum value

[James Almer <jamrial@gmail.com>]

We need a way to signal the frame has a single view that doesn't map to any
particular eye, and it should be the default one.

Now updating the fate test, to show how type and view clashed as is.
