Extract mp3 from Youtube

[dev45]

Hi Friends! I want to know how to Implement a form for Extract mp3 from youtube video. can you help me? i'm developing c#

[morefun0302]

hi @dev45 , you want sample codes or a complete project? basically you can follow the example code by flagbug to develop the program

[dev45]

a complete or a sample code of how to download mp3 directly from a youtube url in a winform c# if it possible

[nightfrost]

I have:

link = textBox1.Text;
IEnumerable<VideoInfo> videoInfos = DownloadUrlResolver.GetDownloadUrls(link, false);
DownloadAudio(videoInfos);

Link is a string, the string is equeals to a text in a text box, this text box contains a youtube url.

private void DownloadAudio(IEnumerable<VideoInfo> videoInfos)
        {
            /*
             * We want the first extractable video with the highest audio quality.
             */
            VideoInfo video = videoInfos
                .Where(info => info.CanExtractAudio)
                .OrderByDescending(info => info.AudioBitrate)
                .First();

            /*
             * If the video has a decrypted signature, decipher it
             */
            if (video.RequiresDecryption)
            {
                DownloadUrlResolver.DecryptDownloadUrl(video);
            }

            /*
             * 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(Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments),
                RemoveIllegalPathCharacters(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) => progressBar1.Value = (int)args.ProgressPercentage;

            /*
             * Execute the audio downloader.
             * For GUI applications note, that this method runs synchronously.
             */
            audioDownloader.Execute();
        }

I pretty much just took Flagbugs console application example, tweaked it a bit for easier user control (A GUI). Link could be:

Link = "http://youtube.com/yourvideo"

hi again i want to know how to make to download mp3 faster and how to cancel the download

[nightfrost]

mp3 should already download fast, depending on the length and quality of the video, I presume. I have heard that different "Qualities" on Youtube have different sound files, the higher the quality, the higher the audio quality, but this I am not sure of. You could always test it?

I will have to test canceling as I have no idea how this could be done. I presume the library uses a stream to get the audio, but I am not sure.

[dev45]

i have a problem why the program when it's downloading don't let minimize and maximize the program

[nightfrost]

You're running it from the "F5" button on debug mode, I guess? Go to your Documents --> Visual Studio 2013 (Or the version you have) --> Projects --> Whatever you named the project --> Click the folder with the name again --> obj --> Debug --> run your projectname.exe

When you run it from Visual Studio there can be some different visual aspects too, such as the border not being seethrough and what not. This is my way of viewing the actual program, but there's probably a much smarter way to do it.

[dev45]

Thank's You Bro!! :+1: i have other question how to make to download a mp3 with 128 bitrate or higher

[dev45]

Hi Man! i'm again i have a problem the program stop working while is downloading the mp3

[nightfrost]

Hey again!

Can't help you with the bitrate, sorry. I have no idea how to do that.

It's maybe because it's extracting the sound? Not sure, though.

[moiseyo]

I have code to download sound from link https://www.youtube.com/watch?v=nZiBINQK_kY

Windows 10 Prof Vs 2013

I found that all entries in object videoInfos ->CanExtractAudio has false value

This related to every link I use on youtuube link above is just a a sample.

Code

private static void DownloadAudio(IEnumerable videoInfos) { if (videoInfos == null) { Console.WriteLine("ERROR: No videoInfos for audio "); result.ok = false; result.Title = "N/A No video Info"; return; } / * We want the first extractable video with the highest audio quality. / var videos = videoInfos .Where(info => info.CanExtractAudio && info.AudioType == AudioType.Mp3) //.Where(info => info.AudioType == AudioType.Mp3) .OrderByDescending(info => info.AudioBitrate) //.First() ;

        if (! videos.Any())
        {
            {
                Console.WriteLine("ERROR: No Valid audio info  ");
                result.ok = false;
                result.Title = "N/A No No Valid audio info ";
                return;
            }
        }

        VideoInfo video = videos.First();
        /*
         * If the video has a decrypted signature, decipher it
         */
        if (video.RequiresDecryption)
        {
            DownloadUrlResolver.DecryptDownloadUrl(video);
        }

        /*
         * 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.
         */

        audioName = Path.Combine(arguments.oDir,
            RemoveIllegalPathCharacters(video.Title) + video.AudioExtension).traslitarateName().replaceAll(" ", "");
        if (arguments.AudioProcess)
        {
            audioName = Path.Combine(arguments.oDir,
            RemoveIllegalPathCharacters(video.Title) + video.AudioExtension);

        }
        if (File.Exists(audioName))
        {
            return;
        }
        var audioDownloader = new AudioDownloader(video, audioName);

        // 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("{0:00} %   ", args.ProgressPercentage * 1);
        //audioDownloader.AudioExtractionProgressChanged += (sender, args) => Console.WriteLine("{0:00} %  ", args.ProgressPercentage * 0.15);
        /*
         * Execute the audio downloader.
         * For GUI applications note, that this method runs synchronously.
         */
        audioDownloader.Execute();
    }

Any Ideas

Best regrad

You can try this with the file extension ".mp3", although the audiobitrate = 128 in the file, but the details of the audiobitrate = null, but it is available. You can use this download audio manner 2160p, 1440p, 1080p, 480p video using ffmpeg will be synthesized audio and video files.

I currently use the following way to get all resolution video, and all have audio.

VideoInfo.cs

new VideoInfo(140, VideoType.Mp4, 0, false, AudioType.Aac, 128, AdaptiveType.Audio), new VideoInfo(171, VideoType.WebM, 0, false, AudioType.Vorbis, 128, AdaptiveType.Audio),

Code

This example is downloaded Mp4 audio. In the program set the file extension ".mp3"

VideoInfo video = videoInfos.First(info => info.VideoType == VideoType.Mp4 && info.Resolution == 0); var audioDownloader = new VideoDownloader(video, Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), RemoveIllegalPathCharacters(video2.Title) + ".mp3")); audioDownloader.Execute();

Code

When you download the 1080p it is no audio Mp4, you can try the following examples.

string arg = "-i " + mp4file + " -i " + mp3file + " -map 0:0 -map 1:0 -codec copy " + outputfile; Process proc = new Process(); proc.StartInfo.WorkingDirectory = Application.StartupPath; proc.StartInfo.FileName = "ffmpeg.exe"; proc.StartInfo.Arguments = arg;

proc.StartInfo.CreateNoWindow = true; proc.StartInfo.UseShellExecute = false; proc.Start();

Note: When your Mp4 and Mp3 file name contains spaces must use the following examples. Otherwise it will fail synthesis files.

mp4file = string.Format(@"""{0}""", savepath + RemoveIllegalPathCharacters(video.Title) + video.VideoExtension);
