Any Half Side By Side videos you can find online needs this feature. You really don't need a sample for this. It's not a rare video format. It's almost like universal standard.
Or, unless your developers never heard of "Half Side by Side" format and have no idea what that is. That will be very interesting.
And more interesting is, DeoVR supported this feature before. Somehow it was gone for more than a year, despite we kept asking it over and over again.
