Hello, We believe this happens because running Unity + 1080p video compression is too demanding for the HoloLens hardware. A possible workaround is to reduce PV resolution and/or framerate.

See [client_stream_pv.py](https://github.com/jdibenes/hl2ss/blob/main/viewer/client_stream_pv.py) lines 32-35 and 79. Supported resolutions and framerates are in [pv_configurations.txt](https://github.com/jdibenes/hl2ss/blob/main/etc/pv_configurations.txt).

Hello, Does the python code receive the id of the object (from `ipc_umq.pull`)?

It seems it is not possible to run two holographic applications simultaneously. Here is an experimental 2D version of the appxbundle that can run alongside other apps: https://github.com/jdibenes/hl2ss/blob/main/etc/hl2ss_1.0.26.0_arm64_FLAT.appxbundle

Hello, It was removed since the calibration data is different for each HoloLens. The empty folder has been re-added as a convenience. It will be automatically populated by scripts calling...

Hello, These errors occur when the server cannot transfer the compressed frames fast enough (low bandwidth/poor connectivity for example). You can try adding a check before the call to `cv2.imshow`...

The Spatial Input stream captures head position and orientation @ 30 Hz. See `head_pose.position` in [client_si.py](https://github.com/jdibenes/hl2ss/blob/main/viewer/client_si.py).

Those vectors encode the orientation of the head.

Hello, There is no functionality to start capturing data from a Unity interface so you would have to implement the button control, but a code example for creating the projectionMatrix...
