NV12 & UYVY was added to allow pass-through (without internal conversions) on all backends (in case someone has the need for it), which previously was only possible on Linux. NV12 is the native format on the OBS Windows backend, and UYVY on the OBS macOS backend. The Linux backend has multiple native formats (GRAY, I420, NV12, YUYV, UYVY).
