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.

Issues with HoloLensForCV

Hello everyone,

I'm trying to get some image processing (object recognition) done with the HoloLens. It seems there is a Project by Microsoft itself which gives access to OpenCV: https://github.com/Microsoft/HoloLensForCV

I don't know where else to ask this, but it doesn't want to work. I had issues to build the samples, but got it fixed by changing the Target Platform Version down to 10.0.15063.0 of all Projects, which was 10.0.16299.0 before. I did put "ComputeOnDevice" as my Startup Project and am trying to put it on the HoloLens Emulator, but it throws "Access Violation" Exceptions at

     latestFrame =
                 _holoLensMediaFrameSourceGroup->GetLatestSensorFrame(
                     HoloLensForCV::SensorType::PhotoVideo);

I really don't know how to fix this.

I attached a screenshot. Thanks for any attempt of helping me.
