Hololens 2: List of Supported Resolutions incomplete

Open lapislazinus opened this issue 5 years ago • 7 comments

The documentation mentions a variety of different camera profiles / resolutions to choose from. However, i only get two supported resolutions at runtime: 2272x1278 and 896x504, with 30 or 15 FPS each. I also noticed that the video stream is not opened using the center camera, but one of the tracking cameras on the side. This suspect this to be related, but i don't know whether i only get those two resolutions because the side camera only supports those or the other way around. I will investigate the issue further soon; any info on this will be much appreciated ;)

I am using Unity 2019.2.19f1

Did some tests; what's weird aswell is that i only get the following 2 available devices (with Modes):

  • No Name, MediaStreamType = VideoRecord, SourceKind = Depth
  • QC Back Camera
    • MediaStreamType: VideoPreview, SourceKind: Color
    • MediaStreamType: Photo, SourceKind: Image
    • MediaStreamType: VideoRecord, SourceKind: Color

Im pretty sure that QC Back Camera corresponds to the Hololens front camera, which is opened by this plugin, although its location attribute says "Panel.Back"

I got the same results with yours. I am using Unity 2019.3

How do you even get this to build for HL2, i only get 24 errors of missing functions. I am using 2019.4 though.

@efsjouw Can you open a separate Issue/Question if you want help? With HL2, you need to build for UWP and ARM64, so the process is a bit different. I guess this project is abandoned though (for HL2 - HL1 should still work), so you might not want to invest your resources here

Alright https://github.com/VulcanTechnologies/HoloLensCameraStream/issues/69

Is there maybe a maintained fork with the necessary changes for the HL2?

I can use this repo with HL2 and Unity 2019.4 without problems. I had some problems with namespaces though, I can't remember exactly what I changed to make it work.
