FFmpegArgs is a cli-wrapper library support generate argument for ffmpeg executable.
The standout feature that many cli-wrapper libraries don't have is the FFmpeg FilterGraph system.

Get it on NuGet Package

  • Support file/url/pipe in/output.
  • Works on most systems - if ffmpeg can execution.
  • 130+ filters, add more in future
  • 380+ filters auto-generate


FFmpegArg ffmpegArg = new FFmpegArg()
    .OverWriteOutput();//global extension

var green_video = ffmpegArg.AddVideoInput(
        new VideoFileInput(@"chromakey.mp4")
            .SsPosition(TimeSpan.FromSeconds(0.5))//input extension ( -ss )
                x => x.ImageInputAVStream//input video stream
                    .R(24)//input, video, per-stream extension ( -r )
var background_videoMap = ffmpegArg.AddVideoInput(new VideoFileInput(@"background.mp4")

var image_maps = green_video.ImageMaps.First()
    .ColorKeyFilter()//ColorKey Filter
        .Color(Color.FromArgb(101, 220, 8))
        .Enable("between(t,0,10)").MapOut//Filter had ITimelineSupport
    .ScaleFilter().W("iw/3").H("ih/3").MapOut//Scale Filter
    .SplitFilter(2).MapsOut;//Split Filter

var overlay_map = image_maps.First()
    //overlay color_key on-center background_video

    new VideoFileOutput(@"out.mp4", overlay_map, background_videoMap.AudioMaps.First())
    .T(TimeSpan.FromSeconds(5))//output extension ( -t )
        x => x.ImageOutputAVStream//output video stream
            .R(24)//output, video, per-stream extension ( -r )
    new VideoFileOutput(@"out2.mp4", image_maps.Last(), background_videoMap.AudioMaps.First())
    .AndSet(x => x.ImageOutputAVStream.R(30)));

var renderResult = ffmpegArg
    .Render(c => c
        .WithFFmpegBinaryPath("path to ffmpeg")//or default ffmpeg from PATH
        .WithWorkingDirectory("path to working folder")//or default Directory.GetCurrentDirectory()

For more example, see FFmpegArgs.Test

  • Option/Flag not found?

We can extend for FFmpegArg, Filter, Input, Output, AVStream by extension.

.SetOption("your option","option value")
.SetOptionRange("your option", val, min, max)
.SetFlag("your flag")

  • Filter not found?

We can write new Filter class, so much example in FFmpegArgs.Filters
