• Block YouTube from source page when trying to download a video with youtube-dl

  18 mars 2018, par user3108268

  E.g. example.com/1 has a video hosted, you run youtube-dl example.com/1 and it all works fine, the video gets downloaded.

  E.g. example.com/2 also has a video, but it also has a YouTube trailer. If you run youtube-dl example.com/2 the hosted video gets completely ignored and only YouTube trailer gets downloaded.

  From what I see in the log is that the wanted local video playlist gets downloaded first and then ignored by getting overwritten by embedded YouTube playlist download.

  You can’t even get the url with --get-url or get format with --list-formats. It always prints the googlevideos URL for the YouTube trailer and lists only the YouTube trailer formats.

  I did manage to pull out the local video URL via --dump-pages and decoding the base64 encoded source. But the problem is that the URL contains a unique token each time the page example.com/2 is called, so passing the unique one-time video URL like e.g. example.com/2/video.php ?token=asdf to youtube-dl won’t download the video.

  So I figured somehow I need to bypass the YouTube trailer source and playlist when calling youtube-dl example.com/2 and trying to download local video and not the YouTube trailer.

• ffmpeg stream video file from ubuntu to youtube

  14 mars 2018, par user3010452

  I’m trying to create a stream to youtube. I could see how preview button changes into enable state. However it never actually changes from offline.
  And it gives me several error. What am I doing wrong ?

• How to marge Youtube video with MP4 using FFMPEG library in Android ?

  27 février 2018, par Apurv Modi

  Here is my code

          String filePrefix = "audio_video";
  
          String fileExtn = ".mp4";
  
  
  
          youtubeURL = "https://www.youtube.com/embed/oEKyXKL25FU";
  
          videoPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/video.mp4";
  
  
  
          File dest = new File(moviesDir, filePrefix + fileExtn);
  
          int fileNo = 0;
  
          while (dest.exists()) {
  
              fileNo++;
  
              dest = new File(moviesDir, filePrefix + fileNo + fileExtn);
  
          }
  
          filePath = dest.getAbsolutePath();
  
  
  
          String[] command = new String[]{"-y", "-i", videoPath, "-i", youtubeURL, "-filter_complex", "[0:a][1:a]amerge=inputs=2[a]", "-map", "0:v", "-map", "[a]", "-c:v", "copy", "-c:a", "libvorbis", "-ac", "2", "-shortest", filePath};
