• Using Node.js module fluent-ffmpeg to convert video but my files end up corrupt

  28 juin 2017, par El Guapo

  i am writing a node based media encoding tool and have found a few good node packages that will help me to do this, but the output files are either totally corrupt or it only encodes half the video.

  The main node package i am using is fluent-ffmpeg, and i am trying it with the following code :

  var ffmpeg = require('fluent-ffmpeg');
  
  
  
  var proc = new ffmpeg({ source: 'uploads/robocop-tlr1_h480p.mov', nolog: false})
  
    .withVideoCodec('libx264')
  
    .withVideoBitrate(800)
  
    .withAudioCodec('libvo_aacenc')
  
    .withAudioBitrate('128k')
  
    .withAudioChannels(2)
  
    .toFormat('mp4')
  
    .saveToFile('output/robocop.mp4',
  
      function(retcode, error){
  
          console.log('file has been converted succesfully');
  
  });

  There is not a problem with the source video as i encoded it just fine using FFmpeg normally with the following comand line string (i run it from a batch file) :

  "c:\ffmpeg\bin\ffmpeg.exe" -i %1 -acodec libvo_aacenc -b:a 128k -ac 2 -vcodec libx264 -b:v 800k -f mp4 "../output/robocop2.mp4"

  Any ideas what i am doing wrong here ?

• Videoshow NPM module with ffmpeg

  5 juillet 2018, par JZG

  I’m trying to use videoshow to convert multiple images to video, I have tried to change my code multiple times but now as you can see this is basically the same as in the module’s description page. Still I am receiving the following error as stated below.

  videoshow(images)
  
      .save('video.mp4')
  
      .on('start', function (command) {
  
          console.log('ffmpeg process started:', command)
  
      })
  
      .on('error', function (err) {
  
          console.error('Error:', err)
  
      })
  
      .on('end', function (output) {
  
          console.log('Video created in:', output)
  
      })

• ffmpeg-php module fails in linux

  26 juillet 2017, par Swati

  I’ve been trying this for a couple of days now. I am trying to install ffmpeg-php on my CentOS server.

  OS : CentOS 6
  PHP : 5.5
  ffmpeg : 1.2.1
  ffmpeg-php : 0.6.0
  The ffmpeg installation went on without a hitch and I am able to convert files back and forth via the CLI.

  While installing ffmpeg-php, I encountered errors while making (after configuring) due to time.h references which was corrected by renaming the files creating with an extension .loT to .lo (as rightly pointed out here)

  Once this was done, the make process went on smoothly and the make install went through without a hitch. However, after specifying the extension=ffmpeg.so in the php.ini file and after restarting Apache, the module doesn’t load or show up in phpinfo().

  The Apache error log shows only "PHP Warning : PHP Startup : Invalid library (maybe not a PHP library) ’ffmpeg.so’ in Unknown on line 0" and nothing else.

  make test also shows the same error and FAILS the associated tests. I’ve checked here which wasn’t very helpful. Also, I read somewhere that it may be the issue with permissions but the permissions for the ffmpeg.so file is 755.

  Any help is appreciated.

  Thanks in advance.
