Video VR 3D 180 or 2D 360 streaming in Firefox Reality or Oculus browser?

VR video is essentially just an mp4 video formated to be watched in a VR headset via the dedicated player or through VR web browsers like Firefox Reality, Oculus browser, or dedicated VR video player.

Can I stream an mp4 file or even an HLS video file stream formatted as VR video?

If this is possible then the VR browser can run the video in a full-screen theater mode formatted in accordance with the meta specifications or by picking up video format from a video name variables (3D, 180, 360).

The market of Cinematic VR is getting bigger and more accessible. It would be great to put more attention to VR Video options and integrations.
