• node.js - Error : ENOENT : no such file or directory, unlink

  10 août 2020, par necroface

  I have the function below to convert a .wav file to .mp3. As you can see, before using the ffmpeg module to convert the audio file, I already check if the file exists or not, then upon conversion, I only keep the new file and delete the old one. But occasionally the console throws me the error Error: ENOENT: no such file or directory, unlink, which means that I unlink (delete) a non-existing file. I cannot understand why, because I already have an existence check even before the conversion, so it is supposed to have existed to be unlinked.

  



  module.exports.convertAndMoveElastic = async (calllog) => {
    let { start, sip_uri, direction, source, destination } = calllog;
    const VNtimezoneOffset = 7 + new Date().getTimezoneOffset() / 60;
    const startTime = new Date(start + VNtimezoneOffset * 3600000 - 60000);
    const date = startTime.getDate() < 10 ? `0${startTime.getDate().toString()}` : startTime.getDate().toString();
    const months = ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun', 'Jul', 'Aug', 'Sep', 'Oct', 'Nov', 'Dec'];
    const month = months[startTime.getMonth()];
    const year = startTime.getFullYear().toString();
    sip_uri = sip_uri || (direction === 'outgoing' ? source : destination);
    const [extension, domain_name] = sip_uri.split("@");
    return new Promise(async (resolve, reject) => {
        const links = await getLinkWithElastic(calllog);
        if (!links) { return reject(); }
        let file_id, filepath;
        for (let link of links) {
            const { callid, sipCallid, uuid, record_path } = link._source;
            if (record_path) {
                let recordPathArr = record_path.split('/');
                file_id = recordPathArr[recordPathArr.length - 1].split('.')[0];
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (!file_id || !fs.existsSync(filepath)) {
                file_id = callid;
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (!file_id || !fs.existsSync(filepath)) {
                file_id = uuid;
                filepath = path.resolve(base_directory, domain_name, 'archive', year, month, date, `${file_id}.wav`);
            }
            if (fs.existsSync(filepath)) { break; }
        }
        if (!fs.existsSync(filepath)) { return reject(); }
        ffmpeg(filepath)
            .audioCodec('libmp3lame')
            .on('error', function (error) {
                reject(error);

• "Error opening filters !" when using fluent-ffmpeg with Node

  3 février 2015, par doremi

  I’m trying to get a basic example of html5 video streaming working in an express node app, but I keep running into ffmpeg errors that I’m unsure of how to resolve.

  The input file/stream is the sample.mp4 located here.

  Complete example :

  var ffmpeg = require('fluent-ffmpeg');
  
  var express    = require('express');
  
  var fs         = require('fs');
  
  var sampleApp  = express();
  
  var videoApp   = express();
  
  
  
  var SAMPLE_SERVER_PORT = 3000;
  
  var VIDEO_SERVER_PORT  = 5000;
  
  
  
  sampleApp.get('/:video', function (req, res) {
  
    var videoURL = 'http://localhost:' + VIDEO_SERVER_PORT + '/' + req.params.video;
  
    return res.end('<video controls="controls" src=" + videoURL +"></video>');
  
  });
  
  
  
  videoApp.get('/:video', function(req, res) {
  
  
  
    res.statusCode = 200;
  
    res.setHeader('content-type','video/mp4');
  
  
  
    var stream = fs.createReadStream('./samples/' + req.params.video);
  
  
  
    var proc = ffmpeg(stream)
  
  
  
      .format('mp4')
  
      .size('320x?')
  
      .videoBitrate('512k')
  
      .videoCodec('libx264')
  
      .fps(24)
  
      .audioBitrate('96k')
  
      .audioCodec('aac')
  
      .audioFrequency(22050)
  
      .audioChannels(2)
  
  
  
      .on('error', function(err) {
  
        console.log('an error happened: ' + err.message);
  
      })
  
  
  
      .pipe(res, { end:true });
  
  });
  
  
  
  var server = sampleApp.listen(SAMPLE_SERVER_PORT, function () {
  
    console.log('Example app listening at http://%s:%s', server.address().address, SAMPLE_SERVER_PORT);
  
  });
  
  
  
  
  
  var videoServer = videoApp.listen(VIDEO_SERVER_PORT, function () {
  
    console.log('Video Server listening at http://%s:%s', server.address().address, VIDEO_SERVER_PORT);
  
  });

  The error (via console) :

  an error happened: ffmpeg exited with code 1: Error opening filters!

  ffmpeg configuration :

  ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass \                                                                         
  
  --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus \
  
  --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --enable-libfaac --enable-libfdk-aac

  Any input would be greatly appreciated.

• NODE.JS using audioconcat , configured ffmpeg but still have prob

  11 mai 2018, par Adnan Khan

  Want to concatenate two audio files. i used an npm package known as audioconcat but when i installed and configured the below code i am confronted with the following error

  Error: Error: Cannot find ffmpeg

  Then I put my problem on stackoverflow. A kind developer suggest me to install ffmpeg also. which i successfully installed and set there path variables but now i am having another issue which tells me that no such file are directry found..i placed my audio files in the same folder of this module.
  here is the error
