ffmpeg .so files for Android Arm64 Build

[HappyStoat]

Hi there,
I like to port your project to Xamarin Android. On Windows I use CMake for the Arm64 built, but I get the following error:
"Could not find release version of library "libavformat.so.58"

It would be super nice if you could upload or send me the necessary .so files, so that I can build on Window for Android Arm64. Unfortunately I don't have Ubuntu and I don't think I can get the files myself.
