Hi @WaGi-Coding,

I just verified with a sample console application that the following will work for your case:

var ffmpeg = new Engine(@"..\..\..\..\..\lib\ffmpeg\v4\ffmpeg.exe");
await ffmpeg.ExecuteAsync(@"-i C:\Temp\a.mp4 -i C:\Temp\a.wav -c:v copy -map 0:v:0 -map 1:a:0 -shortest C:\Temp\new.mp4");

You need to adjust the paths for sure.
In every event that ffmpeg raises Input and Output properties will be null though.
