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.

Streaming Not working

It seems that for some reasons, the live streaming on the Windows Developer Portal doesn´t work when I run application that are using camera frames for some reasons (example: Vuforia, or save the current frame after a gesture).
Why? How to solve his?
Furthermore, the streaming available from the Window Developer Portal needs too often a refresh because sometimes it stops. It´s very uncomfortable for a end-user to refresh the page so often. Is there a way to improve the performance of this streaming?

  • Hello, it won't solve your device portal problem but did you try steaming through the Hololens companion application? You create a local network with your PC/tablet and connect your Hololens on it. There is no delay comparing to the device portal and it does not stop as often.

  • Do you mean the one available in the Windows Store?

  • With that App I don´t need to refresh but still the same problem with Vuforia and each application that use the Camera

  • Yes I meant that one. Ok sorry I can't help you... I hope someone will answer you!

  • I really hope so.. please, someone has an idea to solve this?

  • So, the first part of your question was answered in your other post. As far as the Mixed Reality Streaming stability, I have found my best bet to do it over USB. If you get a good, long USB cable, you can connect to the Device Portal over usb at 127.0.0.1:10080

    This reduces the lag and the disconnections considerably. The other option is to get a portable wifi router that you can use exclusively for the HoloLens and your computer so that you get nothing competing for bandwidth.

  • Thanks Jesse

  • I am experiencing the same problem. Somehow my app won't share the camera with either live streaming on portal site or the Mixed Reality Companion app. The only way I could do live stream is to uncheck PV before the streaming was established, but without PV the background would be just black. I am considering this solution: https://github.com/Microsoft/MixedRealityCompanionKit/tree/master/SpectatorView, but that would be my last resort.

    Hope this would help, and could you letme know if you found a better soluiton.

    Thanks!

  • Even the direct USB from hololens to the laptop is lagging 3-4 secs. Is there any way we can reduce this further?
