UWP Camera Bridge not working

Summarize the bug: Got black screen only when a virtual camera is set with the new UWP Camera Bridge (#74) even when we don't use it.

Other observations Virtual camera is working perfectly in official Camera app from Windows

Reproducible steps Steps to reproduce the behavior:

Download and install UWP Camera Bridge
Configure it on a DirectShow video source
Try to run UWP Sample

Affected Vuforia Engine version: v10.19.3

Affected platform:

Workstation OS: Windows 11 23H2
Platform: Visual Studio 2022
Platform version: 17.8.3

Hello! Thanks for reporting this. Can you specify which exact camera you are using?

Hello! Thanks for reporting this. Can you specify which exact camera you are using?

I tried multiples:

Built-in one (Chicony USB2.0 Camera)
Logitech (C505)
and one with an API (Blackmagic UltraStudio)

All of them makes a black screen if they are added with VuforiaCameraBridgeConfig

We suspect that the problem may be an issue regarding the selection of the correct framerate/resolution when the Camera Bridge is used. Could you try forcing the virtual camera to expose only one resoution/framerate (which you know is supported by the camera) by providing a custom intrinsics.json to the configuration tool (see "Camera Intrinsics" in the Camera Brdige readme)

Also, Windows Media Foundation & the Windows Frame Server background service sometimes end up in a bad state and get stuck (but in that case, the normal Windows Camera app also stops working properly). A machine reboot helps to resolve that.

One more thing: For cameras that are supported by Windows Media Foundation out of the box (= Cameras that already work with Vuforia or the Windows Camera app without installing Camera Bridge) it is not recommended to use Camera Bridge. This is the case for most generic webcams (I suspect this applies to your built-in camera and the Logitech one)

Oh i forgot but i'm already providing an intrinsics.json:

[
  {
    "frameRate": 30,
    "resolution": { "width": 1920, "height": 1080 },
    "focalLength": { "x": 1551.42, "y": 1565.63 },
    "principalPoint": { "x": 827.71, "y": 553.43 }
  }
]

Obviously i already tried to reboot service and computer, i tried to remove the virtual camera and set it again.

I know that is not recommanded, it was just for testing. My purpose is to use an SDI camera with a Blackmagic card in Vuforia, that why i wanted to used UWP Bridge but it does a black screen too.

To further investigate this it would be good if you could capture a full log session of the Sample App + Camera Bridge. Vuforia sends log messages to Windows ETW. The tools to capture these messages should be included in the Windows SDK installation that came with Visual Studio (usually located at C:\Program Files (x86)\Windows Kits\10\bin\10.0.22000.0\x64 - exact SDK version number does not matter for this):

Start log capture (run this with a user that has administrative permissions)

tracelog.exe -start VuforiaLogs -guid "*VuforiaEngine" -f C:\logs.etl
tracelog.exe -enable VuforiaLogs -guid "*VuforiaCameraBridge"

Run the UWP Sample app with Camera Bridge

Stop capture & convert to text

tracelog.exe -stop VuforiaLogs
tracefmt.exe C:\logs.etl -o C:\logs.txt

Compared to the logs you sent above, this will also include logs from the Camera Bridge virtual camera instance that is running in background.

Please share the resulting text file. If you do not feel comfortable sharing it publicly here, feel free to email it to vuforia-feedback@ptc.com.

Compared to the logs you sent above, this will also include logs from the Camera Bridge virtual camera instance that is running in background.

Here is the file but i'm pretty sure this will be useless:

When i attach the svchost.exe from FrameServer into Visual Studio there is no call to VuforiaCameraBridge. These logs were generated with the vuforia-camerabridge-uwp-public-release-10-19-3.
One more thing: I don't know if this could help you, but here is logs from VuforiaCameraBridge when I open Windows Camera with an Blackmagic camera configured (working perfectly): These logs were generated with the vuforia-camerabridge-uwp-public-source-10-19-3 modified.

Ok thanks for that. Summarizing to make sure I got this right:

In the UWP Camera app the virtual camera works fine with DirectShow & your custom BlackMagic build.
When starting a Vuforia app there is no indication that the Camera Bridge is being started (as you don't see any log messages coming from it after "Starting Vuforia Engine instance")

My main suspicion is then that Vuforia Engine is trying to actually use a different camera and not the virtual camera device. We currently don't have an API that allows camera device selection but there are some rules in place to determine a preferred camera (e.g. a camera that the OS reports to be back facing will be preferred over others).

To check if that is the issue, could you try disabling/disconnecting all other camera devices on the system? (ideally there should only be one Media Foundation camera device left - in the UWP Camera app you should only see the Camera Bridge and no "change camera" button in the top right)

Already try that, nothing change

I just tried the sample scene in Unity. In 'Play Mode', it works fine, but if I export the app to UWP, I still get the black screen.

Could you try one more thing: Using the MFTrace tool (part of Windows SDK) it is possible to capture all interactions of an application with Windows Media Foundation. This should give us a bit more detailes what is going on.

1) Install & configure camera bridge, start the Vuforia Native Sample app but don't select Image Target/Model Target just yet. 2) Run C:\Program Files (x86)\Windows Kits\10\bin\10.0.22000.0\x64\mftrace.exe -a VuforiaSample.exe -o C:\mftrace.log 3) In the sample app, open Image Target or Model Target to trigger a start attempt of Vuforia Engine.

Please post the resulting log file here or send it to vuforia-feedback@ptc.com.

Here is mftrace.log:

Thanks for that. It looks like your camera is using ARGB32 image format. We have idetified an issue with handling cameras that use this pixel format in Vuforia.

Is this using your custom Camera Bridge build for the BlackMagic capture device? Is it possible to switch that to RGB24 or NV12 image format instead?

Is this using your custom Camera Bridge build for the BlackMagic capture device?

Yes

Is it possible to switch that to RGB24 or NV12 image format instead?

I received a four 8-bit unsigned components packed into one 32-bit little-endian word. So i have switched to RGB32 and it does same thing.

I just tried V210 and the bridge isn't started even with the Windows Camera app

So i have switched to RGB32 and it does same thing.

Please try using RGB24 (8bit R, 8bit G, 8bit B, 24bit per pixel in total), Engine currently does not support RGB32.

I just tried V210 and the bridge isn't started even with the Windows Camera app

V210 as in "YUV 4:2:2 packed with 10bit componenets"? If so, this also not supported by Engine currently. As YUV format please use NV12 (YUV 4:2:0 with 8bit Y plane + half resolution interleaved UV plane) or YUV2 (8bit interleaved 4:2:2 YUV)

It works with RGB24, but do you know if RGB32 will be supported soon ? Currently i convert RGB32 to RGB24 with opencv but it's not ideal

Thank for confirming that it works with RGB24.

Vuforia Engine 10.21 will support the folloing image formats when Camera Bridge is used: NV12, IYUV, YV12, YUY2, RGB24, ARGB32. We are also making some changes to logging & documentation to make issues like this clearer and easier to diagnose in the future.

For now this case will be closed as Engine currently does not support RGB32. @Rombond Please create a feature request for support of RGB32.
