HoloLens 2: Unable to record videos using HoloLens Video Capture

March 5, 2020 - 6:18am #1

Hi,

I am working on a project where I want to record a video using "HoloLens Video Capture" ( https://docs.unity3d.com/2019.2/Documentation/Manual/windowsholographic-videocapture.html ) and at the same time I want to track a Vuforia-Image.

When I start the video capture via the start menu the video capture works and via the video capture script it does not. The red "recording-icon" is continuously flashing but the video stops after about 1 second.

I already changed the Vuforia-settings in Unity to "Mode_optimize_speed" and tried different video resolutions.

Did I miss something?

Thank you

 

Setup:

- HoloLens 2

- Unity 2019.2

- Vuforia 8.6.10

Unfortunately I can test it but maybe this can help you:

https://docs.microsoft.com/en-us/windows/uwp/audio-video-camera/capture-photos-and-video-with-cameracaptureui

On the other hand its very easy to capture a video with the start menu or holding the volume up and volume down buttons for three seconds will also start the video.

(@huangzejie ) No, not yet.

I know that using the camera for video recording and image target tracking was not possible with Hololens 1. Can you confirm that this is working with Hololens 2 via the start menu?

(@sebben ) Yes, using the start menu it is possible to record a video. But not via script (HoloLens Video Capture)

I used the script for Hololens 1 already so I am not sure if it was updated for Hololens 2 or if it works the same way.

But I also did not find anything specific for Hololens 2...
