Viewing net 3D video by Oculus Quest 2 via https

 support.oculus recommended for local 3D video viewing to put 

{

"format": "3DLR"

}  as a video_name.txt in the video's directory. But adding F to "format": up to "3DLRF" changes nothing. How can I get full-screen mode?

In addition, I uploaded https://syla.top/3D/2KMSM.mp4 with https://syla.top/3D/2KMSM.txt as a video_name.txt, but Quest 2 still shows it side-by-side. Or does such a video_name.txt work with local files only? Then how can I share a video to somebody's Quest 2 with a 3D video from my server?
