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.

Spectator View Calibration Blue Screen with Elgato HD60 S

I'm trying to get the spectator view running with an Elgato HD60 S capture card. However, once I start calibration the video feed is totally blue, similar to the description of an NTSC problem when using a European Blackmagic card.
The video stream works fine when using the Elgato software.
Any help would be greatly appreciated!

    I recently revisited this problem and have finally been able to complete the calibration process. One of the issues I was having was because I hadn't deactivated the "Required SSL connection" option in the Security tab of the device manager. Additionally, the Elgato game capture HD software tends to not exit gracefully, resulting in the calibration not being able to access the camera feed. To rectify this, simply force close the Elgato software using Windows' Task Manager. I occasionally encoutered a problem where the Calibration app didn't close gracefully and needed to force close or even restart my device in order to get it running. I also connected the HoloLens to my PC via USB instead of via WiFi. Some useful information can also be found here: https://github.com/Microsoft/MixedRealityCompanionKit/issues/188

  • Okay, so I've been having a closer look at what's been going on in the background and it seems to be an issue of the Elgato not being detected by the Calibration program. I managed to get a video feed only twice so far with pictures being taken for calibration. However, I got an exception while trying to calibrate with the images and it didn't work. When I try recalibrating the video is again not recognised. I'm pretty sure the problem is with the Elgato, but so far my results are inconclusive and inconsistent.

  • Update: I am getting consistent Video feed using the Elgato HD60 S card, connected to a JVC camcorder. Current method: start calibration application with camcorder turned off. Once the elgato: No Signal screen appears, turn on the device. It should transmit the video. App seems to be running fine, frames are being grabbed and calibration images are being taken.
    My current problem, though, is still the exception I get when trying to complete the calibration. Here's what the Debug has to say about the matter:

    Exception thrown at 0x00007FFA989C9E08 in Calibration.exe: Microsoft C++ exception: web::json::json_exception at memory location 0x000000924B83F758.

  • Currently I am able to get a consistent video feed by starting the calibration application before turning on the camera. After the application starts, images are saved for calibration, yet, I still can't calibrate properly. This is what the Debugger has to say:
