"NuGet\Install-Package EmguFFmpeg".

Usage

Manually download the *.dll files that comply with the license from ffmpeg.org.

using FFmpeg.AutoGen;
using FFmpeg4Sharp;

// Create a mp4 file
var fps = 29.97d;
var width = 800;
var heith = 600;
var outputFile = "path-to-your-file.mp4"; 
using (var muxer = MediaMuxer.Create(outputFile))
{
    using (var vEncoder = MediaEncoder.CreateVideoEncoder(muxer.Format, width, heith, fps))
    {
        var vStream = muxer.AddStream(vEncoder);

        muxer.WriteHeader();

        using (var vFrame = MediaFrame.CreateVideoFrame(width, heith, vEncoder.PixFmt))
        {
            for (var i = 0; i < 30; i++)
            {
                // your code to fill AVFrame data, 
                // default is green frame.
                //FillYuv420P(vFrame, i); 
                vFrame.Pts = i;
                foreach (var packet in vEncoder.EncodeFrame(vFrame))
                {
                    packet.StreamIndex = vStream.Index;
                    muxer.WritePacket(packet, vEncoder.TimeBase);
                }
            }
        }
        muxer.FlushCodecs(new[] { vEncoder });
        muxer.WriteTrailer();
    }
