• "Invalid or unexpected token" error when trying to execute ffmpeg build on lambda

  4 janvier 2019, par almarc

  I have a node.js script that uses ffmpeg to convert mp4 downloaded from YT to mp3 and save to Amazon S3. Uploading using the serverless framework. The "ffmpeg" file is included in the main directory (with .yml), downloaded from here :
  https://johnvansickle.com/ffmpeg/

  The code :

  'use strict'
  
  process.env.PATH = process.env.PATH + ':/tmp/'
  
  process.env['FFMPEG_PATH'] = '/tmp/ffmpeg';
  
  const BIN_PATH = process.env['LAMBDA_TASK_ROOT']
  
  process.env['PATH'] = process.env['PATH'] + ':' + BIN_PATH;
  
  
  
  module.exports.download_mp3 = function (event, context, callback)
  
  {
  
    require('child_process').exec('cp /var/task/ffmpeg /tmp/.; chmod 755 
  
    /tmp/ffmpeg;', function (error, stdout, stderr) {
  
    if (error) 
  
    {
  
      console.log('An error occured', error);
  
      callback(null, null)
  
    } 
  
    else 
  
    {
  
      var ffmpeg = require('ffmpeg');
  
      const aws = require('aws-sdk')
  
      const s3 = new aws.S3()
  
      const ytdl = require('ytdl-core');
  
  
  
      function uploadFromStream(s3) {
  
        const stream = require('stream')
  
        var pass = new stream.PassThrough();
  
  
  
        var params = {Bucket: "some-bucket", Key: "some-key", Body: pass};
  
        s3.upload(params, function(err, data) {
  
          console.log(err, data);
  
        });
  
        console.log("Should be finished")
  
        callback(null)
  
      }
  
  
  
      let stream = ytdl("some-video-id", {
  
        quality: 'highestaudio',
  
        filter: 'audioonly'
  
      });
  
  
  
      ffmpeg(stream)
  
        .audioBitrate(128)
  
        .format('mp3')
  
        .on('error', (err) => console.error(err))
  
        .pipe(uploadFromStream(s3), {
  
          end: true
  
      });
  
    }})
  
  }

  When triggered, the function writes an error in logs :

  It’s, most definetely, an error in the "ffmpeg" file I’ve mentioned above (link provided). But I don’t know what’s the exact issue, I followed the first answer here : https://stackoverflow.com/questions/47882810/lambda-not-connecting-to-ffmpeg to include the ffmpeg build.

• How to overlay two audio files Node JS FFmpeg

  27 avril 2023, par Markusha Boec

  My code works only once correctly and starts to work correctly only after I restart my program. The first time the code outputs the correct audio, which is superimposed one on top of the other, and the second time only one audio with a duration of 15 seconds. I'm trying to get two audio files to help Node.js with FFMPEG. Do you have any ideas how to fix it ? My code is shown below.

  


  


  


  async songMerge(bg_id, text) {
    const bgMusic = await this.airtable
      .table("BackgroundMusic")
      .select({ view: "View", filterByFormula: `ID = '${bg_id}'` })
      .firstPage();
    if (!bgMusic.length) throw new Error("is not found");

    const result = await fetch(
      `https://api.elevenlabs.io/v1/text-to-speech/VR6AewLTigWG4xSOukaG`,
      {
        method: "POST",
        headers: {
          accept: "audio/mpeg",
          "xi-api-key": "token",
          "Content-Type": "application/json",
        },
        body: JSON.stringify({
          text,
          voice_settings: {
            stability: 0,
            similarity_boost: 0,
          },
        }),
      }
    );

    const audioBuffer = await result.arrayBuffer();
    const filePath = path.join(__dirname, "../../../", "audio.mp3");

    await fs.writeFileSync(filePath, Buffer.from(audioBuffer));

    const test = await fetch(`${bgMusic[0].fields.AudioLink}`);
    const audioBufferr = await test.arrayBuffer();

    const filePathh = path.join(__dirname, "../../../", "test.mp3");
    await fs.writeFileSync(filePathh, Buffer.from(audioBufferr));

    await mergeAudio(filePathh, filePath);
  }

  


  


  



  And the merge Audio function :

  


  async function mergeAudio(bgMusic, path) {
  return await command
    .addInput(path)
    .addInput(bgMusic)
    .complexFilter([
      {
        filter: "amix",
        inputs: ["0:0", "1:0"],
      },
    ])
    .outputOptions("-y") // add this line to overwrite the output file
    .output(`./overlayed.mp3`)
    .setStartTime("00:00:00")
    .setDuration("15")
    .on("error", function (err) {
      console.log(err);
    })
    .on("end", function () {
      return "ok";
    })
    .run();
}

  so i ask some one he told me the exec stop php script and never give me

  You can't get the progress directly if you are using exec, because the php script is stopped until ffmpeg closes. (Because exec returns the whole execution output)
  
  
  
  You should use popen, for being able to get the output from the process in real time (without reading any file) for parse and show the progressbar
  
  
  
  Here is a example for get the output: 
  
  
  
  When you get the progress info from ffmpeg, you can use your code for parse it and show your progressbar

  this is my popen script

  <?php 
  
  
  
  $handle = popen ("ffmpeg.exe -i files/fz.mp4 -ab 192k files/vdf.mp3 2>&1 ", 'r');
  
  $handles = (string)$handle;
  
  $line = "";
  
  
  
  while (false !== ($char = fgetc($handle)))
  
  {
  
    if ($char == "\r")
  
    {
  
      // You could now parse the $line for status information.
  
      echo "$line\n";
  
      $line = "";
  
    } else {
  
      $line .= $char;
  
    }
  
    ob_flush();
  
    flush();
  
  }
  
  pclose ($handle);
  
  
  
  
  
      //get duration of source
  
      preg_match("/Duration: (.*?), start:/", $handles, $matches);
  
  
  
      $rawDuration = $matches[1];
  
  
  
      //rawDuration is in 00:00:00.00 format. This converts it to seconds.
  
      $ar = array_reverse(explode(":", $rawDuration));
  
      $duration = floatval($ar[0]);
  
      if (!empty($ar[1])) $duration += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $duration += intval($ar[2]) * 60 * 60;
  
  
  
      //get the time in the file that is already encoded
  
      preg_match_all("/time=(.*?) bitrate/", $handles, $matches);
  
  
  
      $rawTime = array_pop($matches);
  
  
  
      //this is needed if there is more than one match
  
      if (is_array($rawTime)){$rawTime = array_pop($rawTime);}
  
  
  
      //rawTime is in 00:00:00.00 format. This converts it to seconds.
  
      $ar = array_reverse(explode(":", $rawTime));
  
      $time = floatval($ar[0]);
  
      if (!empty($ar[1])) $time += intval($ar[1]) * 60;
  
      if (!empty($ar[2])) $time += intval($ar[2]) * 60 * 60;
  
  
  
      //calculate the progress
  
      $progress = round(($time/$duration) * 100);
  
  
  
  
  
  
  
  
  
      echo '<br /><br />¡Su video fue convertido correctamente! <br /><br />Link al archivo:';
  
  
  
  
  
      echo "Duration: " . $duration . "<br />";
