This is its GUID for BGRA/X 8:8:8:8. The UVC 1.5 spec [1] only defines GUIDs for YUY2, NV12, M420 and I420. This seems to be an extension documented in the Microsoft Windows Media Format SDK[2]. This Media Format SDK defines this GUID as corresponding to `MEDIASUBTYPE_RGB32`. Note that in my case, the FX3 UVC can output either channel order, BGR or RGB or any other mix for that matter. Since Linux commit 1b8dc32286a1a ("[media] uvcvideo: Add GUID for BGR 8:8:8") defined a GUID for `MEDIASUBTYPE_RGB24` channel order as BGR, keep this change consistent and define `MEDIASUBTYPE_RGB32` as BGR as well.
