Cannot get compositor to render live video with MixedRealityCompanionKit example by Microsoft
Hey all, I'm hoping someone can help me narrow down my issue as I am out of troubleshooting options.
So I am following the MixedRealityCompanionKit sample project listed here to try and get high definition video of a hololens experience. I have followed every step of the instructions listed EXACTLY as they appear. I have even redownloaded the project fresh several times (and retried all the steps), and restarted my computer several times trying to reset the experience, but I have not been able to get the unity compositor to render any video feed.
I am using Unity 5.6.3p2, Blackmagic_DeckLink_SDK_10.9.10, Opencv_3.2 and a Cannon camera (without the sdk hooked up since it said it was optional). If I open the BlackMagic Media viewer, I am able to see a video stream coming in from my camera. However, in Unity my compositor is always a greyed out box. When I open the project (after following the setup instructions) I get the following errors listed below. However I am able to clear the errors and they don't seem to affect the project being able to run
After searching online for any solution, I found this post which weirdly seemed to help slightly https://forums.hololens.com/discussion/9027/spectator-view-how-to-get-the-camera-feed-in-compositor#latest
So I opened the sample project in Unity 5.5, then reopend the project in 5.6. After that, all the errors/warnings were cleared. When I opened the compositor window I was able to see a black background with a hologram in view (so it seems like this is a step in the right direction?). However, no matter what I try I cannot get the live video feed to appear. I am positive no other application is using my camera's video feed. This is what my compositor window looks like currently:
When I take a picture, it just shows an enlarged view of that window (black background with the hologram laid over it) but no real world environment. If I take a video, it doesn't matter how long I try and record for, it always produces a blank video in the "HologramCapture" folder that last about 1 second. I am completely out of options and don't know what else I can do to troubleshoot this issue. Any suggestions or directions would be greatly appreciated. Thanks!
P.S. The very first time I ran through the tutorial and ran the application, I was able to see my camera's video feed in the compositor briefly and I captured an image of it working. However, the very next time I tried to run the application, the feed was gone and I have not been able to get it working again. I tried redoing the sample project several times to no avail.

Sorry for the novel of a post. Anyone have any suggestions?
