ThumbGen

ThumbGen is a customizable cross-platform, blazing-fast video thumbnail generator for .NET 8. This versatile tool allows you to choose between two rendering engines: System.Drawing (for Windows) or ImageMagick. With ThumbGen, you can effortlessly generate thumbnails for your videos with various options and configurations.

Example Usage

var thumbnailGenerator = ThumbnailGeneratorBuilder
    .Create()
    .WithFFmpegVideoCapture()
    .UseSystemDrawingRenderer()
    .ConfigureRendering(renderingOpts => renderingOpts
        .WithFrameSize(-1, 108)
        .WithTiling(options =>
        {
            options.Columns = 4;
            options.Rows = 4;
        })
        .WithBorder(new Size(8, 8))
        .UseBackgroundGradient(
            new LinearGradient(Color.Cyan, Color.Blue, 45))
        .WithTimeCode(14f)
        .UseTimeCodeBackgroundColor(Color.Black)
        .PreserveFrameAspect(false)
        .UseAspectOverlap(true)
        .UseAspectOverlapColor(Color.Black)
        .UseTimeCodeColor(Color.White))
    .Build("input-video.mp4");

var opts = new ThumbGenOptions()
    .WithStartTime(TimeSpan.FromSeconds(60))
    .WithInterval(TimeSpan.FromSeconds(5))
    .WithOutputFilename(Path.GetFullPath("./output.jpg"))
    .WithWebVTT("storyboard.vtt");

await thumbnailGenerator.ExecuteAsync(opts);

To Use magick renderer, just replace UseSystemDrawingRenderer with UseMagickRenderer

Feel free to customize the options and rendering settings based on your specific requirements.

FFmpeg

ThumbGen relies on FFmpeg libraries for its functionality. Ensure you set ffmpeg.RootPath with the full path to the FFmpeg libraries for the proper execution of the tool.

using FFmpeg.AutoGen;

ffmpeg.RootPath = "/your/path/to/ffmpeg/libraries/"

Installation

To get started with ThumbGen, simply install the necessary NuGet packages:

dotnet add package ThumbGen
dotnet add package ThumbGen.Magick # if using ImageMagick renderer

Ensure that you also set the FFmpeg library path as mentioned in the dependencies.
