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.
Get position & rotation of VideoMediaFrame
This website and this sample code show how to access the video frames using the latest Windows 10 release, version 1607 (14393 build). I'm considering to do it this way because Unity currently does not provide a way to access the video camera at 30fps (except for saving the video to disk, which I do not want to do). However, once I get the video frame VideoMediaFrame, I'm not sure how to get the position and rotation of that video frame. I know I can access VideoMediaFrame.FrameReference.CoordinateSystem, which returns a SpatialCoordinateSystem, but even if I can get that, how do I get the position & rotation from that?
I'm assuming that if I use DirectX, there's a way to use that SpatialCoordinateSystem for getting the frame's position & rotation. But if I'm using Unity, is there a way to do this?
