Snapshot of 360 deg panorama video is not restricted to current field of view
When a snapshot is taken of a 360 deg panorama video, the resulting image is not restricted to the current field of view and view point. Instead of a nicely projected image, reflecting what the user is seeing, the snapshot instead includes the whole 360 deg. image which is not what is expected.
As an example, try downloading and viewing the public available video at https://vimeo.com/215985064, open it in VLC player and take a snapshot.
