Windows OBS in Windows ARM runs well, but no video capture sources work #4248

Closed nowcodingaway closed 3 years ago

nowcodingaway commented 3 years ago

Platform

Operating system and version: Windows 10 ARM Build 21301.rs.prerelease.210123-1645 (but all versions before as well) OBS Studio version: 26.1.1 (64 Bit)

Expected Behavior

Create scene Add video capture device / camera / capture card See preview of video in properties preview window Be able to use video source in scene

Current Behavior

Select any input (have tried different USB cameras, Capture cards including Elgato 4k etc) See properties and dropdown change as expected Do NOT see any video feed/input. Black screen remains.

Steps to Reproduce

  1. Install Windows ARM
  2. Install OBS
  3. Add new 'video capture device' source
  4. Choose any video camera / usb input / video source

Additional information

Have installed other software such as Zoom and cameras are working fine. So they are present and correctly driven within windows without any problems. Only OBS is having problems showing any video input.

Have tried changing all properties for all cameras and inputs but no difference is made.

Are you self-compiling? We don't offer ARM as a currently supported platform.

Please include a session log.

This is using the new x64 emulation I assume?

Additionally, try this:

Windows 10's April 2018 Update adds new privacy settings for microphones and cameras, which can block them from use. The camera privacy settings also affect capture cards. These settings are opt-in. To allow apps like OBS to use your microphone or camera again, follow these steps. 1) Open the Settings app. 2) Go to Privacy -> Camera for capture cards and webcams, and turn "Allow apps to access your camera" on.

No. This is the regular windows OBS build. It runs using emulation.

All features are working wonderfully and at speed. The only error is the video issue described here. Fixing it would allow full and fast use on arm installs without the need for a specific arm build as far as I can currently tell.

So this is trying to progress that use case and support the growing number of arm installs without huge efforts if possible.

I do understand if you opt to close the issue. But I remain hopeful.

Thanks. I appreciate the pointer. I have done all of this. As noted camera and inputs all working fine in other software / zoom. And all properties for each camera correctly read into the OBS properties window. It simply doesn’t render the actual video view.

I will get a session log for you and attach in due course. Sorry for the the oversight there.

Aha I imagine this is the problem

DShow: Failed to create ICaptureGraphBuilder2 (0x800700C1): %1 is not a valid Win32 application

I also see Adapter 0: Parallels Display Adapter (WDDM)

Is this being run in a VM? OBS does not typically work very well inside VMs, and we don't support running it in a VM.

nowcodingaway commented 3 years ago

I can confirm it is. And I understand the position entirely. I guess given other apps (zoom) worked and that other OBS features I've tested are doing ok, I was hopeful I could move to the windows version of OBS due to missing features on the Mac builds (e.g. no GDI, No StreamFX etc etc).

I fully anticipate you'll close this issue for the time being. Thank you for at least giving it some attention. Fingers crossed for the future.

Heads up: this is apparently fixed in the latest Insider build on ARM64.

nowcodingaway commented 3 years ago

I was just heading here to note this fix. Will be doing full testing tomorrow but I can confirm capture/camera absolutely show up now.
