Stuck on 'Initializing MediaFrameSourceGroups...' #46

Closed ShumWengSang closed 2 years ago

ShumWengSang commented 2 years ago

Hi, I'm trying to get the samples to run on the HoloLens 1. However, I'm stuck on the Initializing MediaFrameSourceGroups. The following exception had happened.

Viewing this, it appears that the constructor for SensorFrameStreamer is throwing an error. Not too sure why, though... After that, I get the below, which makes sense because it is not initialized (from the exception above)

Not too sure why this happened, and this isn't the first time I'm deploying to the HoloLens. I built x86 on Debug/Release, using Unity 2019.4 and VS2019. I'm using the master branch as well. I've also built the HoloLensForCV project from source, x86 Debug/Release.

Any ideas why this could be happening, or some idea of where I can look for a fix?

Upon recloning the project the issue was resolved. Not sure why it didn't work.
