Mixed Reality Streaming

Caution

Because of loopback isolation, you can't connect to mixed reality streaming from inside an app on a device.

HoloLens supports live preview of mixed reality via chunked download of a fragmented mp4.

Mixed reality streams share the same set of parameters to control what's captured:

  • holo: capture holograms: true or false
  • pv: capture PV camera: true or false
  • mic: capture microphone: true or false
  • loopback: capture app audio: true or false

If none of these are specified, then holograms, photo/video camera, and app audio will be captured.

If any are specified, the unspecified parameters will default to false

Optional parameters (HoloLens 2 only)

  • RenderFromCamera: render from perspective of photo/video camera: true or false (defaults to true)
  • vstab: enable video stabilization: true or false (defaults to false)
  • vstabbuffer: video stabilization buffer latency: 0 to 30 frames (defaults to 15 frames)
