OBS 31.1 is our first release with Windows on Arm (WoA) support. Windows on Arm support in OBS is experimental and does not support all our standard features at this time.
By default, the virtual camera is not enabled on portable builds even though 32-bit, 64-bit, and ARM virtual camera DLLs are included.

There's an installation script included, but it has not been modified to support ARM.
Running the script will enable the virtual camera in:
If you'd like to enable virtual camera in native ARM64 apps, doing so will disable virtual camera in emulated x64 apps.
Switch Virtual Camera from emulated x64 to native ARM64:
regsvr32.exe /i /u obs-virtualcam-module64.dll
regsvr32.exe /i /s obs-virtualcam-module-arm64.dll
If you'd like to switch back to x64, replace steps 3 & 4 with the following:
regsvr32.exe /i /s obs-virtualcam-module64.dll
regsvr32.exe /i /u obs-virtualcam-module-arm64.dll
More work on our side is required to properly support both x64 and ARM64 at the same time.
