                    var pipeSource = new StreamPipeSource(fs);
                    var arguments = await FFMpegArguments

@Toemsel I have released version 4.3 in which -y is removed from InputPipeArgument. Could you try again

Pipe is indeed broken

Tried 3.3 - 4.2 ffmpeg versions. Lib version: 4.2

Edit: After debugging: You do require to pass a format as an argument. E.g.:

public override string Text => $"-y -f avi {Writer.GetStreamArguments()} -i \"{PipePath}\"";

works

Edit edit: works even without providing a format by removing the ‘-y’ (override) param.
