• How do install ffmpeg in android for youtube-dl

  21 novembre 2019, par Wasp Nesser

  I have got a python code for downloading a video (from youtube) and converting to mp3. I used youtube-dl for these. Python code works in computer. But that error occurred in my android :

  youtube_dl.utils.DownloadError: ERROR: ffprobe/avprobe and ffmpeg/avconv not found. Please install one. [Program finished]

  I couldn’t find how to install these requirments in android . I use application called pydroid3 for executing python codes , installing python libraries and terminal staff. I tried to install ffmpeg and ffprob libraries with pip .But it didn’t helped me. After I tried to execute

  adb shell pm install ffmpeg 

  And It didn’t helped me to.

  This is my code :

  import youtube_dl
  
  import os 
  
  outtmpl = "%(playlist_title)s-%(playlist_uploader)s /%(playlist_index)s %(title)s-%(uploader)s.%(ext)s"
  
  ydl_opts = {
  
      'format': 'bestaudio/best',
  
      'postprocessors': [{
  
          'key': 'FFmpegExtractAudio',
  
          'preferredcodec': 'mp3',
  
          'preferredquality': '192',
  
      },
  
          {'key': 'FFmpegMetadata'},
  
      ],
  
      'outtmpl' : outtmpl,
  
  }
  
  
  
  url = input("Enter url : ")
  
  
  
  with youtube_dl.YoutubeDL(ydl_opts) as ydl:
  
  
  
      ydl.download([url])

• How to concat two videos of different format with stretching the videos

  25 juillet 2020, par Xnox

  I want to concat two videos together but in doing so, the second video is being stretched. Here is my code

  


  $command = "ffmpeg -i ../unprocessed/{$temp_name} -vf \"[in]drawtext=fontsize=47:fontcolor=white:fontfile='../fonts/Nunito/nunito.ttf':text='{$name}':x=10:y=(h) - 120, drawtext=fontsize=35:fontcolor=white:fontfile='../fonts/Amiri/amiri.ttf':text='{$second}':x=10:y=(h) - 80, drawtext=fontsize=30:fontcolor=white:fontfile='../fonts/Amiri/amiri.ttf':text='{$hospital}':x=10:y=(h-40)[out]\" -y ../unprocessed/{$edited}";
    system($command);
    unlink("../unprocessed/{$temp_name}");

    $video_1 = $_POST["video1"];
    $video_2 = $edited;

    try{

      //generating intermediate files
      $intermediate1 =  "intermediate".rand(100000, 1000000000).rand(100000, 1000000000).".mpg";
      $command = "ffmpeg -i ../unprocessed/{$edited} -qscale 0 -r 25 ../unprocessed/{$intermediate1}";
      system($command);
      unlink("../unprocessed/{$edited}");

      $intermediate2 =  "intermediate".rand(100000, 1000000000).rand(100000, 1000000000).".mpg";
      $command = "ffmpeg -i ../admin/videos/{$video_1} -qscale 0 -r 25 ../unprocessed/{$intermediate2}";
      system($command);

      $outputfile_temp = "upload".rand(100000, 1000000000).rand(100000, 1000000000).rand(100000, 1000000000).".mp4";

      $command = "ffmpeg -i \"concat:../unprocessed/{$intermediate1}|../unprocessed/{$intermediate2}\" -c copy ../merged_videos/{$outputfile_temp}";
      system($command);
      unlink("../unprocessed/{$intermediate1}");
      unlink("../unprocessed/{$intermediate2}");

      $outputfile = "upload".rand(100000, 1000000000).rand(100000, 1000000000).rand(100000, 1000000000).".mp4";
      $command = "ffmpeg -i ../merged_videos/{$outputfile_temp} ../merged_videos/{$outputfile}";
      system($command);
      unlink("../merged_videos/{$outputfile_temp}");
