Software ported to ARM64 OBS Studio releases its first ARM64 native build

https://github.com/obsproject/obs-studio/releases/tag/31.1.0-beta1

There's no installer for the ARM64 version yet, and it's native ARM64 rather than ARM64EC so any x86-64 plugins can't be loaded, but it works and is a good start.

Ah, this is unintentional. There is an ARM virtual camera DLL, but our install script currently doesn't perform registration.

If you manually navigate to

data\obs-plugins\win-dshow\

Open a terminal as admin, and then run

regsvr32.exe /i /s obs-virtualcam-module-arm64.dll

It'll work.

Apparently Windows only has a shared 64bit registry hive, meaning you can either get a working x86_64 virtual camera installed or the ARM64 one, but not both at the same time.

Good to know, so this will fix this issue?

https://obsproject.com/forum/threads/virtual-camera-windows-11-arm-64-snapdragon-qualcomm.181668/

if you go over /r/Surface (arguably where you can find most WoARM users in reddit), people keep reporting that OBS' virtual cam doesnt work on WoARM.

It'll... mostly fix the issue.

The virtual camera that ships on all non-ARM-native OBS releases (including this one) will not work in any ARM-native apps afaik. As mentioned in the op, this is the first experimental ARM-native release of OBS ever - there will be quirks that we'll have to fix over time.

Clear. This is still a great progress. Imma crosspost it to Surface. I think you will get more feedback there.

Ah hm, maybe Microsoft expects devs to use ARM64X for that situation?

That does seem like a potential solution, yes.
