MediaToolkit

MediaToolkit provides a straightforward interface for handling media data, making tasks such as converting, slicing and editing both audio and video completely effortless.

Under the hood, MediaToolkit is a .NET wrapper for FFmpeg; a free (LGPLv2.1) multimedia framework containing multiple audio and video codecs, supporting muxing, demuxing and transcoding tasks on many media formats.

Features

Resolving metadata
Generating thumbnails from videos
Transcode audio & video into other formats using parameters such as:
- Bit rate
- Frame rate
- Resolution
- Aspect ratio
- Seek position

- Media format
Convert media to physical formats and standards such as:
- Standards include: FILM, PAL & NTSC
- Mediums include: DVD, DV, DV50, VCD & SVCD
Supports custom FFmpeg command line arguments
Raising progress events

Grab thumbnail from a video

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_Image.jpg"};

using (var engine = new Engine())
{
    engine.GetMetadata(inputFile);
    
    // Saves the frame located on the 15th second of the video.
    var options = new ConversionOptions { Seek = TimeSpan.FromSeconds(15) };
    engine.GetThumbnail(inputFile, outputFile, options);
}

Retrieve metadata

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};

using (var engine = new Engine())
{
    engine.GetMetadata(inputFile);
}

Console.WriteLine(inputFile.Metadata.Duration);

Basic conversion

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_New_Video.mp4"};

using (var engine = new Engine())
{
    engine.Convert(inputFile, outputFile);
}

Convert Flash video to DVD

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_New_DVD.vob"};

var conversionOptions = new ConversionOptions
{
    Target = Target.DVD, 
    TargetStandard = TargetStandard.PAL
};

using (var engine = new Engine())
{
    engine.Convert(inputFile, outputFile, conversionOptions);
}

Transcoding options FLV to MP4

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_New_Video.mp4"};

var conversionOptions = new ConversionOptions
{
    MaxVideoDuration = TimeSpan.FromSeconds(30),
    VideoAspectRatio = VideoAspectRatio.R16_9,
    VideoSize = VideoSize.Hd1080,
    AudioSampleRate = AudioSampleRate.Hz44100
};

using (var engine = new Engine())
{
    engine.Convert(inputFile, outputFile, conversionOptions);
}

Cut video down to smaller length

var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_ExtractedVideo.flv"};

using (var engine = new Engine())
{
    engine.GetMetadata(inputFile);

    var options = new ConversionOptions();
    
    // This example will create a 25 second video, starting from the 
    // 30th second of the original video.
    //// First parameter requests the starting frame to cut the media from.
    //// Second parameter requests how long to cut the video.
    options.CutMedia(TimeSpan.FromSeconds(30), TimeSpan.FromSeconds(25));

    engine.Convert(inputFile, outputFile, options);
}

Subscribe to events

public void StartConverting()
{
    var inputFile = new MediaFile {Filename = @"C:\Path\To_Video.flv"};
    var outputFile = new MediaFile {Filename = @"C:\Path\To_Save_New_Video.mp4"};
    
    using (var engine = new Engine())

        engine.ConvertProgressEvent += ConvertProgressEvent;
        engine.ConversionCompleteEvent += engine_ConversionCompleteEvent;
        engine.Convert(inputFile, outputFile);
