• ENOENT Error in Node When Calling Ffmpeg binary from Fluent-Ffmpeg Api

  7 novembre 2018, par Peter

  Background

  I am wiring up a firebase function in node. Purpose is to parse an inbound audio clip to a set length. Using ffmpeg and fluent-ffmpeg.

  Problem

  When the function is triggered in firebase, I am getting ENOENT error when Fluent-Ffmpeg attempts to access the Ffmpeg binary

  Firebase Debug Output

  Error : Error : spawn
  ./Cloud/functions/node_modules/ffmpeg-binaries/bin/ffmpeg ENOENT
  at exports._errnoException (util.js:1018:11)
  at Process.ChildProcess._handle.onexit (internal/child_process.js:193:32)
  at onErrorNT (internal/child_process.js:367:16)
  at _combinedTickCallback (internal/process/next_tick.js:80:11)
  at process._tickDomainCallback (internal/process/next_tick.js:128:9) code : ’ENOENT’, errno :
  ’ENOENT’, syscall : ’spawn
  ./Cloud/functions/node_modules/ffmpeg-binaries/bin/ffmpeg’, path :
  ’./Cloud/functions/node_modules/ffmpeg-binaries/bin/ffmpeg’,
  spawnargs : [ ’-formats’ ]

  Expected Outcome

  Inbound file is downloaded to a temp directory, cropped, and re-uploaded to firebase storage as the cropped file.

  Environment

  • mac client / firebase storage
  • node v8.1.0
  • ffmpeg v3.2.2
  • fluent-ffmpeg v2.1.2

  Code [Updated To Reflect Svenskunganka’s Change. Now Works]

  const ffmpeg = require('fluent-ffmpeg');
  
  const PREVIEW_PREFIX = 'preview_';
  
  
  
  exports.generatePreviewClip = functions.storage.object('audioFiles').onChange(event => {
  
  
  
        //console.log('Times this function has run: ', run++);
  
  
  
        const object = event.data; // The Storage object.
  
        const fileBucket = object.bucket; // The Storage bucket that contains the file.
  
        const filePath = object.name; // File path in the bucket.
  
        const contentType = object.contentType; // File content type.
  
        const resourceState = object.resourceState; // The resourceState is 'exists' or 'not_exists' (for file/folder deletions).
  
        const metageneration = object.metageneration; // Number of times metadata has been generated. New objects have a value of 1.
  
  
  
        // Exit if this is triggered on a file that is not an audio file.
  
        if (!contentType.startsWith('audio/')) {
  
          console.log('This is not an audio file.');
  
          console.log('This is the file:', filePath);
  
          return;
  
        }
  
  
  
        // Get the file name.
  
        const fileName = path.basename(filePath);
  
        console.log('Working with filename', fileName);
  
        // Exit if the file is already an audio clip.
  
        if (fileName.startsWith(PREVIEW_PREFIX)) {
  
          console.log('Already a preview clip.');
  
          return;
  
        }
  
  
  
        // Exit if this is a move or deletion event.
  
        if (event.data.resourceState === 'not_exists') {
  
          console.log('This is a deletion event.');
  
          return;
  
        }
  
  
  
        // Exit if file exists but is not new and is only being triggered
  
        // because of a metadata change.
  
        if (resourceState === 'exists' && metageneration > 1) {
  
          console.log('This is a metadata change event.');
  
          return;
  
        }
  
  
  
        // Download file from bucket.
  
  
  
        const bucket = gcs.bucket(fileBucket);
  
        const tempFilePath = path.join(os.tmpdir(), fileName);
  
        return bucket.file(filePath).download({
  
          destination: tempFilePath
  
        }).then(() => {
  
  
  
          console.log('Audio file downloaded locally to temp directory', tempFilePath);
  
  
  
      var ffmpegPath = require("ffmpeg-binaries").ffmpegPath();
  
      var ffprobePath = require("ffmpeg-binaries").ffprobePath();
  
  
  
      // Generate a croped file using ffmpeg.
  
      var command = new ffmpeg(tempFilePath);
  
          command.setFfmpegPath(ffmpegPath);
  
          command.setFfprobePath(ffprobePath);
  
  
  
          command
  
                .setStartTime('00:00:03')
  
                .setDuration('10')
  
                .output(tempFilePath)
  
                .on('end', function() {
  
                      console.log('Audio Crop Done Successfully');
  
                 })
  
                 .on('error', function(err)
  
                 {
  
                    console.log('Error:', err);
  
                 }).run();
  
  
  
                }).then(() => {
  
          console.log('Preview file created at', tempFilePath);
  
          // We add a 'preview_' prefix to the audio file name. that's how it will appear in firebase.
  
          const previewFileName = PREVIEW_PREFIX + fileName;
  
          console.log('previewFileName is', previewFileName)
  
          const previewFilePath = path.join(path.dirname(filePath), previewFileName);
  
          console.log('previewFilePath is', previewFilePath);
  
          // Uploading the preview file.
  
          return bucket.upload(tempFilePath, {destination: previewFilePath});
  
        // Once the file has been uploaded delete the local file to free up disk space.
  
        }).then(() => fs.unlinkSync(tempFilePath));
  
  
  
        // [END audio file generation]
  
  
  
      });

  Things I Have Tried

  • I can execute ffmpeg from the command line
  • sudo chmod -R u+x ffmpeg-binaries/
  • ffmpeg set in global path
  • used ffmpeg.exe binary in setFfmpegPath, got same result
    • Error : Error : spawn ./Cloud/functions/node_modules/ffmpeg-binaries/bin/ffmpeg.exe ENOENT
  • played with numerous different setFfmpegPath path structures, e.g :
    • ./Cloud/functions/node_modules/ffmpeg-binaries/bin/ffmpeg
    • node_modules/ffmpeg-binaries/bin/ffmpeg
    • ./Cloud/functions/node_modules/ffmpeg-binaries/bin/

  Thanks for any suggestions.

  1er novembre 2013, par jeanmarie grall

  il semble qu’avec la dist (3.0.11) et le plugin Comments (3.2.7), il y ait une double définition de l’ID forum dans les articles :
  une 1ère fois dans la dist > article.html (L55) puis dans le plugin > comments\inclure\forum.html (L3)
  La ligne en question :
  Du coup, ça provoque une erreur de validation HTML...

  Proposition de b_b : "Je pense qu’il serait "logique" de déplacer l’ancre en question dans inclure/forum de la dist pour fixer le bp. "
