Get the download URLs
// Our test youtube link string link = "insert youtube link"; /* * Get the available video formats. * We'll work with them in the video and audio download examples. */ IEnumerable<VideoInfo> videoInfos = DownloadUrlResolver.GetDownloadUrls(link);
Download the video
/* * Select the first .mp4 video with 360p resolution */ VideoInfo video = videoInfos .First(info => info.VideoType == VideoType.Mp4 && info.Resolution == 360); /* * Create the video downloader. * The first argument is the video to download. * The second argument is the path to save the video file. */ var videoDownloader = new VideoDownloader(video, Path.Combine("D:/Downloads", video.Title + video.VideoExtension)); // Register the ProgressChanged event and print the current progress videoDownloader.DownloadProgressChanged += (sender, args) => Console.WriteLine(args.ProgressPercentage); /* * Execute the video downloader. * For GUI applications note, that this method runs synchronously. */ videoDownloader.Execute();
Download the audio track
/* * We want the first extractable video with the highest audio quality. */ VideoInfo video = videoInfos .Where(info => info.CanExtractAudio) .OrderByDescending(info => info.AudioBitrate) .First(); /* * Create the audio downloader. * The first argument is the video where the audio should be extracted from. * The second argument is the path to save the audio file. */ var audioDownloader = new AudioDownloader(video, Path.Combine("D:/Downloads", video.Title + video.AudioExtension)); // Register the progress events. We treat the download progress as 85% of the progress and the extraction progress only as 15% of the progress, // because the download will take much longer than the audio extraction. audioDownloader.DownloadProgressChanged += (sender, args) => Console.WriteLine(args.ProgressPercentage * 0.85); audioDownloader.AudioExtractionProgressChanged += (sender, args) => Console.WriteLine(85 + args.ProgressPercentage * 0.15); /* * Execute the audio downloader. * For GUI applications note, that this method runs synchronously. */ audioDownloader.Execute();
