• ffmpeg video unable to play properly in most video players

  7 septembre 2022, par Lars

  I'm trying to set up a node.js app that allows me to download files from a web interface.
I'm using yt-dl to get the video and audio stream and ffmpeg to pipe those streams into an mp4. This works and returns a mp4 file.

  


  Now the only issue I have is that when I play the file through most video players, the video player is unable to seek, or skip through the song. I found somewhere deep down on a forum that means that that means the mp4 headers are not working but that is all I could find.
Here is my code, almost unchanged from this response on another thread.

  


  Can anyone provide a solution for this issue.

  


  ytdl.getInfo(link, options).then(info => {
        audioStream = ytdl.downloadFromInfo(info, { ...options, quality: 'highestaudio' });
        videoStream = ytdl.downloadFromInfo(info, { ...options, quality: 'highestvideo' });
        // create the ffmpeg process for muxing
        ffmpegProcess = cp.spawn(ffmpegPath, [
            // supress non-crucial messages
            '-loglevel', '8', '-hide_banner',
            // input audio and video by pipe
            '-i', 'pipe:3', '-i', 'pipe:4',
            // map audio and video correspondingly
            '-map', '0:a', '-map', '1:v',
            // no need to change the codec
            '-c', 'copy',
            // output mp4 and pipe
            '-f', 'matroska', 'pipe:5'
        ], {
            // no popup window for Windows users
            windowsHide: true,
            stdio: [
                // silence stdin/out, forward stderr,
                'inherit', 'inherit', 'inherit',
                // and pipe audio, video, output
                'pipe', 'pipe', 'pipe'
            ]
        });
        audioStream.pipe(ffmpegProcess.stdio[3]);
        videoStream.pipe(ffmpegProcess.stdio[4]);
        ffmpegProcess.stdio[5].pipe(result);
    });


  


• How to pass a youtube video's audio url as ffmpeg source

  8 janvier 2020, par CrystallVR

  Im trying to get my discord bot to play the audio from any youtube videos using the video’s url from youtube-dl (the audio url) as the ffmpeg path/source. I got it to work kind of but, while testing, the ffmpeg throws an error in the middle of the audio and the process ends. Here is the error :
  https://i.imgur.com/uCy8SfK.png

  I’ve tried to play the same exact song by downloading it and using the file’s path as ffmpeg source path and it worked fine.

  Here is how i start the ffmpeg process :

              return Process.Start(new ProcessStartInfo
  
              {
  
                  FileName = "ffmpeg.exe",
  
                  Arguments = $"-xerror -i \"{path}\" -ac 2 -f s16le -ar 48000 pipe:1",
  
                  UseShellExecute = false,
  
                  RedirectStandardOutput = true
  
              });

  path is the audio url from youtube-dl process. (can also see the url in the error screenshot)

  And here is how i get the link from youtube-dl :

  Process youtubedl;
  
  
  
  
  
                  ProcessStartInfo youtubedlGetTitle = new ProcessStartInfo()
  
                  {
  
                      FileName = "youtube-dl",
  
                      Arguments = $"--get-title --get-duration --get-url {url}",
  
                      CreateNoWindow = true,
  
                      RedirectStandardOutput = true,
  
                      UseShellExecute = false
  
                  };
  
                  youtubedl = Process.Start(youtubedlGetTitle);
  
                  youtubedl.WaitForExit();

  url is a normal youtube video link.

  I just started working with ffmpeg and youtube-dl so there probably are some stupid rookie mistakes that i’m not aware of. I would appreciate any guidance and/or explanation of what I did wrong.
