• FFMPEG Video not working on Social Media Platforms (Flutter-FFMPEG)

  29 avril 2022, par Raj Dhakad

  I am using Flutter-FFMPEG a Flutter library based on Mobile FFMPEG. I am creating a video from a list of .bmp images. The video works plays normally in devices media player on android or desktop.

  


  But when I tried to share that video on social media like say Instagram it says file format not supported.

  


  It didn't use to work on WhatsApp but after some googling, I made some changes and it works on WhatsApp and Youtube now but not on Instagram, Linkedin, etc.

  


  void _runFFmpeg() async {
    print('Run FFMPEG');
   
    var dir = await getApplicationDocumentsDirectory();
    var output = await getExternalStorageDirectory();
    String videoSize = '$ImageWidth:$ImageSize';
    print("${ImageWidth}x$ImageSize");
    var arguments = [
      "-y", // replace output file if it already exists
      "-i", "${output.path}/frame_%d.bmp",
       
      "-s", '${ImageWidth}x$ImageSize',
      "-framerate", "30", // framrate
      
      "-c:v", "libvpx",
      
      '-ab', '128k',
      '-ar', '44100',
      '-strict', 'experimental',
     
      "-vcodec", "libx264",

      "-pixel_format", "yuv420p",

      "-preset", "ultrafast",

      "-tune", "animation",

      "${output.path}/test.mp4"
    ];
   
    await _flutterFFmpeg.executeWithArguments(arguments).then((rc) {
      print('Process done with $rc');
      
    });


  


  


  


  • The plugin I am using (Flutter-FFMPEG) didn't support libx264

    


  


  • I tried using '-profile:v' to baseline but that gives an error, saying Error setting profile to baseline.

    


  


  • Also, I tried to first make a .webm file and then convert that to mp4. I was also able to use '-profile:v' when converting .webm to mp4 and gave no error but the output video didn't work on Social Media platforms.

  Our friend Monty Montgomery (creator of the Vorbis audio codec used in WebM) has started a video series about digital media. The first episode is an excellent overview of "the technical foundations of modern digital media."

  You can stream WebM versions of the video in your favorite WebM-enabled browser or download it to your desktop and watch it one of many WebM-enabled media players. Supported browsers and players are listed on our site.
