Media Track Mixer Page (WinUI 3)

This provides a reuseable WinUI 3 page with an interface that allows for extracting/combining media tracks.

How to use

Include this library into your WinUI solution and reference it in your WinUI project. Then navigate to the MediaTrackMixerMainPage when the user requests for it, passing a MixerProps object as parameter. The MixerProps object should contain the path to ffmpeg, the paths to the input media files, and optionally, the full name of the Page type to navigate back to when the user is done. If this last parameter is provided, you can get the path to the files that were generated on the Media Track Mixer page. If not, the user will be navigated back to whichever page called the Media Track Mixer page and there'll be no parameters.

private void GoToMixer(){
  var ffmpegPath = Path.Join(Package.Current.InstalledLocation.Path, "Assets/ffmpeg.exe");
  var mediaPath = Path.Join(Package.Current.InstalledLocation.Path, "Assets/image.png");
  var secondMediaPath = Path.Join(Package.Current.InstalledLocation.Path, "Assets/video.mp4");
  Frame.Navigate(typeof(MediaTrackMixerMainPage), new TourProps { FfmpegPath = ffmpegPath, MediaPath = [mediaPath, secondMediaPath], TypeToNavigateTo = typeof(MainPage).FullName });
}

protected override void OnNavigatedTo(NavigationEventArgs e)
{
    //outputFiles is sent only if TypeToNavigateTo was specified in MixerProps.
    if (e.Parameter is List<string> outputFiles)
    {
        Console.WriteLine($"{outputFiles.Count} files were generated");
    }
}
