• How To fix "PHP Fatal error : Class 'ffmpeg_movie' not found" Error in PHP

  19 janvier 2019, par Ajay Katariya

  I have installed FFMPEG in my server for video conversions into different sizes of videos within my WordPress site running on PHP 5.6/Linux. Previously all things were working fine but today suddenly I got one error like :

  "PHP Fatal error : Class ’ffmpeg_movie’ not found".

  PHP Warning : PHP Startup : Unable to load dynamic library ’/opt/cpanel/ea-php56/root/usr/lib64/php/modules/ffmpeg.so’ - /opt/cpanel/ea-php56/root/usr/lib64/php/modules/ffmpeg.so : cannot open shared object file : No such file or directory in Unknown on line 0

  I have searched solution for this error, so I got one solution like include autoload.php file. Which I have already included.

  So can anyone help me to solve out this problem ?

• "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.

• pydub .export() issue - "wave.Error : # channels not specified"

  6 novembre 2018, par Jeremy

  I’m trying to cut a clip from an mp3 using the pydub library. Exporting the clip is giving me a bit of an issue.

  I’ve tried exporting as both .mp3 and .wav. I’m sure it’s something silly I’ve done on my end. Pydub seems great so far, I’m just messing something up along the way.

  The export portion of the my code is as follows :

  def cut_clip(track, start, stop):
  
      full_file = pydub.AudioSegment.from_file(track, format="mp3")
  
      clip = full_file[start:stop]
  
      return 
  
  
  
  def create_clip_file():
  
      global clip
  
      clip = cut_clip('test.mp3', 2200000, 2280000)
  
      clip = pydub.AudioSegment.export("clip.wav", format="wav")
  
      print("%s is written." % clip)
  
      new_file_length = get_track_length(clip)
  
  
  
  create_clip_file()

  Here is the Traceback.

  subprocess.call(['ffmpeg', '-y', '-f', 'mp3', '-i', 'test.mp3', '-acodec', 'pcm_s16le', '-vn', '-f', 'wav', '-'])

  Does anyone happen to see what I’m doing wrong here ?

  I am able to cut the clip using ffmpeg but I was really trying to wrap my head around pydub.
