Error when using FFMpeg in a 64-bit .NET Framework 4.8 application with FFmpeg.AutoGen 7.0

Question

I'm facing an issue when trying to use FFmpeg in my .NET Framework 4.8 application (64-bit) with FFmpeg.AutoGen 7.0. When I try to call any FFmpeg method, such as ffmpeg.av_version_info() in the constructor, I encounter the next "Not supported method" error:

System.NotSupportedException HResult=0x80131515 Mensaje = El método especificado no es compatible. Origen = FFmpeg.AutoGen.Bindings.DynamicallyLoaded Seguimiento de la pila: at FFmpeg.AutoGen.Bindings.DynamicallyLoaded.DynamicallyLoadedBindings.<>c.b__6_1165() at FFmpeg.AutoGen.Bindings.DynamicallyLoaded.DynamicallyLoadedBindings.<>c.b__6_454() at FFmpeg.AutoGen.Abstractions.ffmpeg.av_version_info()

My binaries path contains:

FFmpeg/bin:

avcodec-61.dll

avdevice-61.dll

avfilter-10.dll

avformat-61.dll

avutil-59.dll

postproc-58.dll

swresample-5.dll

swscale-8.dll

FFmpeg/include

libavcodec

libavdevice

libavfilter

libavformat

libavutil

libpostproc

libswrseample

libswscale

I'm using the FFmpeg binaries obtained from GitHub (https://github.com/Ruslan-B/FFmpeg.AutoGen) and I'm specifically working with FFmpeg version 7.0. This is the code snippet:

public sealed unsafe partial class VideoPlayer : Form
{
    private bool _isPlaying = false;
    private Thread playbackThread;
    private int _videoStreamIndex;
    private AVFormatContext* _formatContext;
    private AVCodecContext* _codecContext;        
    private SwsContext* _swsContext;

    public VideoPlayer()
    {
        InitializeComponent();  
        FFMpegBinariesHelper.RegisterFFMpegBinaries(); // FFmpeg registration
        DynamicallyLoadedBindings.Initialize();            
        Console.WriteLine($"FFmpeg version info: {ffmpeg.av_version_info()}"); // Error         occurs here
    }
}

Packages should be added from NuGet, not as downloads from GitHub. It's quite possible the wrong binaries were loaded. Does the problem appear if you create a completely separate new project and add the package reference? — Panagiotis Kanavos

@PanagiotisKanavos, I agree, the packets should be added from Nuget as I did. The problem is that some codecs and DLLs are not available for being downloaded from Nuget. Instead of that, you must get them from GitHub project. — auetic

It was such a project destination platform error. My x64 bit platform was missconfigured, so I just changed it to x64 bits as follows:
