Because the official FFmpeg respository doesn’t compile for Windows on ARM by default, I need to add a unofficial build into the project. For all other platforms it works automatically, therefore I only want to add the unofficial build, if the user is building for Windows on ARM.

I tried specifying it in the .csproj file the following way:

<ItemGroup Condition="'$(RuntimeIdentifier)' == 'win-arm64'"

    <Content Include="ffmpeg.exe">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> 
    </Content> 

    <Content Include="ffprobe.exe">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory> 
    </Content> 

</ItemGroup>

With that attempt, the build works, but the files I want included do not get included. I attempted excluding every other platform with “!=” as well and if I do that, the files do get included, but on every platform, the excluding therefore does no work

If anybody could help me with that, that would be awesome
