With recent updates to the Sphere app, it's possible to send out a stream with lower values such as 180 degrees or 270 degrees.
However, the client player must be compatible with streams that don't cover a full 360 degrees of horizontal stitch.
If a specific client player is only compatible with streams that cover the full 360 degrees, it's possible to add blank panels or images to fill the remaining area not covered by live video so that a full 360 degree stitch is generated for monitoring or streaming.
Blank panels or images are added using the Sphere app on the iPad that is performing the stitch.
The Sphere app used for monitoring on iPhones or iPads can handle these types of streams with reduced resolution.
