Hairsational Thank you so much!
As I was researching about this, I didn't find any VR Camera that can encode and output in AV1 format directly. All of their outputs are in either H.264/AVC or H.265/HEVC.
I think they didn't support AV1 in VR Cameras because of the long time it takes to encode?
Your statement makes the most sense. Many thanks again!
