Hello everyone.

We have decided to phase out the Mixed Reality Forums over the next few months in favor of other ways to connect with us.

The first way we want to connect with you is our mixed reality developer program, which you can sign up for at https://aka.ms/IWantMR.

The plan between now and the beginning of May is to clean up old, unanswered questions that are no longer relevant. The forums will remain open and usable.

On May 1st we will be locking the forums to new posts and replies. They will remain available for another three months for the purposes of searching them, and then they will be closed altogether on August 1st.

So, where does that leave our awesome community to ask questions? Well, there are a few places we want to engage with you. For technical questions, please use Stack Overflow, and tag your questions using either hololens or windows-mixed-reality. If you want to join in discussions, please do so in the HoloDevelopers Slack, which you can join by going to https://aka.ms/holodevelopers. And always feel free to hit us up on Twitter @MxdRealityDev.

Recording a Unity app that uses the webcam

I'd like to record a demo for a Unity app and the app needs to use the webcam to take photos. Regardless of whether I record the video through device portal or Cortana, it stops as soon as the app accesses the webcam. Is there any way to do MR capture "over" the app using webcam?

  • @ContextVR That's what I thought. Thanks for confirming.

    BTW someone pointed me to "Microsoft Hololens" companion app in Windows Store, which is a third option for MR capture. Although it doesn't solve the issue, there is an interesting difference vs. Cortana recording or device portal. Instead of interrupting the video streaming, my app is blocked at the line of starting photo mode, until the MR capture is stopped on the desktop side. It seems there's a priority order in using the webcam: companion app > user app > Cortana / device portal.

  • Yeahy, push the boundaries of science and technology! We are in the 21st century, but we are still not able to have two applications share a camera...

    Please Microsoft, do something about this, it wouldn't be the hardest problem you have solved so far considering the huge technological achievement that Hololens is.
