robman has just created a new issue for https://github.com/w3c/mediacapture-depth:

== Re-add the camera/depth map intrinsics ==

I think these should at least be 'optional' e.g. if available - especially on mobile platforms (which is really just Android right now).

In the Android Camera API these values are available - see https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html  

Specifically this https://developer.android.com/reference/android/hardware/camera2/CameraCharacteristics.html#LENS_INTRINSIC_CALIBRATION

(NOTE: Optional - The value for this key may be null on some devices.)

Also somewhat related:

- https://developer.android.com/reference/android/hardware/camera2/CameraMetadata.html#REQUEST_AVAILABLE_CAPABILITIES_DEPTH_OUTPUT

Also see this relevant document (especially the camera intrinsics, depth map and pose sections) https://developer.android.com/training/camera2/Dynamic-depth-v1.0.pdf

@astojilj I think it was a bit draconian removing them all in #168 to force webcam style limitations onto mobile platforms.

Thoughts @huningxin  @anssiko ?
