• ERROR : "Cannot Find FFMPEG" on Google Cloud Compute Engine Debian Wheezy 7.8 Managed Instance even though it's installed

  4 octobre 2015, par DynamoBooster

  I wrote a Node.JS application that uses the fluent-ffmpeg module to watermark videos uploaded on the platform. I pushed the code to a my Google Cloud Compute Engine project, and every time I get Error : Cannot Find FFMPEG. I ssh’d into the instance once it was created and ran these commands to install FFMPEG before actually testing out the code. I am not sure what is causing the error because after this I am positive that FFMPEG is installed.

  sudo apt-get update
  
  sudo apt-get install -y ffmpeg
  
  export FFMPEG_PATH="/usr/bin/ffmpeg"
  
  export FFPROBE_PATH="/usr/bin/ffprobe"

  Below is my FFMPEG code

  function generate_thumbnail(name, path){
  
    logging.info("Generating Thumbnail");
  
    ffmpeg(path)
  
     .setFfmpegPath('/usr/bin/ffmpeg') 
  
     .setFfprobePath('/usr/bin/ffprobe')
  
     .on('end', function() {
  
          upload_thumbnail(name);
  
          logging.info("Thumbnail Generated and uploaded");
  
          return;
  
      })
  
    .on('error', function(err, stdout, stderr) {
  
          logging.info('ERROR: ' + err.message);
  
          logging.info('STDERR:' + stderr);
  
    })
  
    .on('start', function(commandLine) {
  
         logging.info(commandLine);
  
    })
  
    .screenshots({
  
      count: 1,
  
      filename: name + '_thumbnail.png',
  
      folder: 'public/images/thumbnails/'
  
    });
  
  }

• ffmpeg throwing "errorMessage" : "spawn ffmpeg ENOENT"

  My ffmpeg function thats running as a shell command isnt working. I think its because ’ffmpeg’ isnt really referring to anything. I have the ffmpeg node module in my bundle, but i dont know the execFile command is referring to it here.

  Im following aws-lambda-ffmpeg as an example of how to call this particular function. They are referring to ’ffmpeg’ as a 64-bit linux build they created from John Vansickle’s static FFMPEG builds in their gulp function.

  I want to know how to replace ’ffmpeg’ with something that will just recognize it like a node_module without having to do the whole gulp static build process. To my understanding the only reason they are doing that is to get the latest build which i really dont need.

  If I am wrong and a static build using gulp is needed for another reason please let me know.

  function ffmpegProcess(description, cb) {
  
  console.log('Starting FFmpeg');
  
  
  
  child_process.execFile(
  
      'ffmpeg',
  
      [
  
          '-y',
  
          '-loglevel', 'warning',
  
          '-i', 'download',
  
          '-c:a', 'copy',
  
          '-vf', scaleFilter,
  
          '-movflags', '+faststart',
  
          '-metadata', 'description=' + description,
  
          'out.' + config.format.video.extension,
  
          '-vf', 'thumbnail',
  
          '-vf', scaleFilter,
  
          '-vframes', '1',
  
          'out.' + config.format.image.extension
  
      ],
  
      {
  
          cwd: tempDir
  
      },
  
      function(err, stdout, stderr) {
  
          console.log('FFmpeg done.');
  
          return cb(err, 'FFmpeg finished:' + JSON.stringify({ stdout: stdout, stderr: stderr}));
  
      }
  
  );
  
  }
