• How can I use ffmpeg with youtube-dl ?

  18 octobre 2018, par Dani

  I have this "setup", but it stopped working (I did not change anything in the code) :

    private Process StartFfmpeg(string URL)
  
      {
  
          string args = $"/C youtube-dl --ignore-errors -o - {URL} | ffmpeg -err_detect ignore_err -i pipe:0 -ac 2 -f s16le -ar 48000 pipe:1";
  
          return Process.Start(new ProcessStartInfo
  
          {
  
              FileName = "cmd.exe",
  
              Arguments = args,
  
              UseShellExecute = false,
  
              RedirectStandardOutput = true,
  
              RedirectStandardError = false,
  
              CreateNoWindow = true,
  
          });
  
      }

  (I get the stream by using
  Stream stream = StartFfmpeg(URL).StandardOutput.BaseStream;)
  It just freezes. It doesn’t throw any error (in a try/catch block) and I have the latest version of ffmpeg & youtube-dl. I’ve tried using older versions with no success.
  How can I get it working again ? (This is my first post, sorry if its very bad)

• download youtube video as audio file, with URL in filename, to a specific output directory

  9 octobre 2018, par thanks_in_advance

  I do this to download a video as an audio file (mp3), with the video’s youtube URL (URI actually) in the audio file’s filename (I like having the URI in the filename because it helps me identify which video I grabbed the audio from) :

  youtube-dl --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the file downloads to the same directory that contains youtube-dl.exe

  I do this to download a youtube video as an audio file (mp3) to a specific output directory :

  youtube-dl -o "C:\Documents\Downloads\%(title)s.%(ext)s" --extract-audio --audio-format mp3 --prefer-ffmpeg --ffmpeg-location "C:\FFMPEG" "https://www.youtube.com/watch?v=k1-TrAvp_xs" --audio-quality 0

  The con with this approach : with this command, the downloaded audio file’s filename doesn’t contain the youtube video’s URI.

  My Question : How can I combine the above 2 commands such that the downloaded audio file doesn’t have either of the cons mentioned above ?

  When Icecast servers turns off, FFmpeg trying to reconnect but with only one attempt. Here is error which i get and my script.
