ARM Support

[rwedoff]

Are there plans to support ARM64? It seems that Microsoft is pushing for ARM PCs and I don't believe ScreenRecorderLib will work on those.

I can compile for ARM by targeting .NET 6, but i have no windows on ARM devices to test on, so i'll have to look into an emulator or something. I'll gladly accept help from anyone with knowledge of windows on ARM :)

[k1mmm]

@sskodje I got an ARM machine to test on if you ever need =)

I could build ScreenRecorderLib itself for ARM64. But Test app requires .net framework and old version of Visual studio(2019) does not support ARM64 native build. So I tried with Visual Studio 2022 and its output runs on my ARM64 machine.

Alright, good to know :)

[toruki13]

If anyone gets to build it let me know! thnks!

[sskodje]

I made an ARM64 release, if someone could test in on ARM hardware. If it works well, i can add it to NuGet from next release.

ScreenRecorderLib.ARM64.zip

@sskodje My build outputs are ARM64 native both TestApp and Lib dll and they works very well on my Snapdragon X Elite machine but with my app and your Lib dll pair went fail. I guess my check out is 6.2.0 and it may not fully synchronized with your ones. So let me try your output both app and lib dll You should build TestApp for ARM64 (!ARM64EC && !AnyCPU) :-)

thanks

Windows event viewer shows as below

Did you retarget TestApp to .NET (core) ?

Edit: Here is TestApp converted to .NET 8 and compiled for ARM64. I was not able to compile .net framework for ARM64. net8.0-windows8.0.zip

[ybbahg]

I didn't change build configuration from 6.2.0 master Targets .net framework 4.8 app and lib both As I mentioned before I could build it with VS 2022 not with older versions.

here's your test app test result When I tried to run, it requested .net runtime for 'x64'

So I have installed dotnet 8 for both of x64 and ARM64 It does not run still and found crash result from event viewer

Hmm.. .net framework 4.8 did not work for me due to missing libraries, but 4.8.1 eventually compiled. Let's see if it works.

TestApp dotnet framework 481 ARM64.zip

@sskodje Now it works great :-)

[sskodje]

I added ARM target to relese 6.3.0. I hope it works :)

Thanks!!
