Node-fluent-ffmpeg: Video codec is not available

Created on 20 May 2016 · 13Comments · Source: fluent-ffmpeg/node-fluent-ffmpeg

Hi,

As i try to encode files, the only video codec that works is "mpeg4".

When i try mpeg2 or libx264, h264, vp9, mjpeg, or others, it doesn't work, i have an error message
"Video codec mpeg2 is not available".

i have listed the available codecs with "ffmpeg -codecs" and i have them all

what is the issue there ?

thnaks

best regards

The codec is installed because it can decode it but doesn't necessarily mean you can encode with it.

If you use the built in methods you can check which encoders fluent-ffmpeg thinks it can work with.

const FfmpegCommand = require('fluent-ffmpeg');

FfmpegCommand.getAvailableEncoders((err, encoders) => {
  console.log('getAvailableEncoders', encoders);
});

I have the same issue. I have h264 listed as a codec but not an encoder. I was able to use libx264.

(new FfmpegCommand('/input/path/to/file.avi')).videoCodec('libx264').format('mp4').save('/output/path/to/file.mp4')

Please post your code, the error message and ffmpeg output as well as the output from ffmpeg -codecs.

Look at the 2nd and 3rd arguments for the 'error' handler, those contain ffmpeg stdout and stderr.

OK so my encode.html file code is :

 <head>
  <title>encode</title>
</head>

<body>
  <h1>Welcome to Meteor!</h1>

  {{> inputFile}}
</body>

<template name="inputFile">
   <form>
    <input type="file" class="input_file">
    <SELECT name="nom" class="aspect_ratio">
    <OPTION>16:9</OPTION>
    <OPTION>4:3</OPTION>
    </SELECT>
    <SELECT name="nom" class="codec">
    <OPTION>mpeg4</OPTION>
    <OPTION>vp9</OPTION>
    <OPTION>mpeg</OPTION>
    <OPTION>h264</OPTION>
    <OPTION>mjpeg</OPTION>
    <OPTION>hevc</OPTION>
    </SELECT>
    <input type="submit" value="Go" class="btn btn-primary">
  </form>
</template>


  <template name="show_file">

  </template>

The encode.js file is :

  Template.inputFile.events({
    'click .btn': function (evt) {
      evt.preventDefault();
      var input = $('.input_file').val(); // récupération avec Jquery de la valeur de l'input
      var inputAr = $('.aspect_ratio').val(); // récupération avec Jquery de la valeur de l'input
      var inputCodec = $('.codec').val(); // récupération avec Jquery de la valeur de l'input
      var inputok = input.replace("C:\\fakepath\\", "C:\\bin\\");
      var inputClean  = input.replace("C:\\fakepath\\", "");

       var searchedId = files.insert({name: inputok, status: 'inital', createdAt: new Date()});
       console.log(inputok);
       console.log(inputClean);
       console.log(inputCodec);

      //var searchId = files.findOne({}, {sort: {'_id': -1}});
       var inputId = searchedId;


          Meteor.call('sendEncode',inputok, inputAr, inputCodec, inputId, inputClean, function(error,response){
            if(error){
              console.log('ERROR :', error);
            }else{
              console.log('Response :', response);
            }
          })
       }

  });

and the encode.js file on the server folder is :

  Meteor.startup(function () {
    // code to run on server at startup

var  ffmpeg = Meteor.npmRequire('fluent-ffmpeg');
// var Fiber = Meteor.npmRequire('fibers');

ffmpeg.setFfmpegPath('C:\\bin\\ffmpeg.exe')
ffmpeg.setFfprobePath('C:\\bin\\ffprobe.exe')

//  ffmpeg.ffprobe('C:\\bin\\walking.avi', function(err, metadata) {
//     console.dir(metadata);
//     console.dir(err);
// });

 // var resolve = Meteor.wrapAsync(ffmpeg.on);

Meteor.methods({    

            'sendEncode': function(input, inputAr, inputVc,inputId,inputCl){ // récupération du paramètre passé par le meteor.call

            var FileToEncode = ffmpeg(input)
                  // set video bitrate
                  .videoBitrate(1024)
                  // set target codec
                  .videoCodec(inputVc)
                  // set aspect ratio
                  .aspect(inputAr)
                  // set size in percent
                  .size('50%')
                  // set fps
                  .fps(24)
                  // set audio bitrate
                  .audioBitrate('128k')
                  // set audio codec
                  .audioCodec('libmp3lame')
                  // set number of audio channels
                  .audioChannels(2)
                  // set output format to force
                  .format('avi')
                  // setup event handlers
                  .on('end', Meteor.bindEnvironment(function(stdout, stderr) {
                    console.log('file has been converted succesfully');
                     files.update({ _id: inputId }, { $set: { status: 'done' } });
                  }))
                  .on('error', function(err, stdout, stderr) {
                    console.log('an error happened: ' + err.message);
                  })
                   .on('stderr', function(stderrLine) {
                     console.log('Stderr output: ' + stderrLine);
                  })
                   .on('stdout', function(stdoutLine) {
                     console.log('Stdout output: ' + stdoutLine);
                  })
                  .on('progress', function(progress) {
                     console.log('Processing: ' + progress.percent + '% done');
                  })
                  // save to file
                  .save('C:\\apps\\'+ inputCl +'.avi');

so when i select a codec different from mpeg4 ( VP9 for example), i always get an error message : on my server console :
An error happened: Video codec VP9 is not available

the app is running on meteor

i don't have other error message as STDERR

and my ffmpeg -codecs command tells me :

Do you have libvpx installed ?

njoyard on 23 May 2016

I am having the same issue. Did this ever get resolved?

I can run this from command line:

ffmpeg -rtsp_transport tcp -i rtsp://rtsp_url:10556/axis-media/media.amp -vcodec libx264 -acodec aac -f mp4 -t 60 output.mp4

But when running from fluent-ffmpeg I get the following error emitted:

Error: Video codec libx264 is not available

@ryanstinson what does ffmpeg -codecs output ?

njoyard on 17 Jul 2016

I get the same problem on the pi 3. It works with same command line with -vcodec libx264 but setting it with .videoCodec('libx264') gives: Error: Video codec libx264 is not available

@Climax777 first, you're using avconv which is not compatible with fluent-ffmpeg. Second, you'll have to check that the corresponding libx264 is installed and that your ffmpeg version is built with support for it.

njoyard on 18 Aug 2016

libx264 is installed and working from command line with the same command
fluent uses with ffmpeg. For some reason fluent doesn't sense it. Output of
ffmpeg and avconv is identical for the -codecs flag and 99% of other flags.

@njoyard How do I check if libx264 library is installed? That's not something that comes with the standard installation of ffmpeg?

Thanks

The codec is installed because it can decode it but doesn't necessarily mean you can encode with it.

If you use the built in methods you can check which encoders fluent-ffmpeg thinks it can work with.

const FfmpegCommand = require('fluent-ffmpeg');

FfmpegCommand.getAvailableEncoders((err, encoders) => {
  console.log('getAvailableEncoders', encoders);
});

I have the same issue. I have h264 listed as a codec but not an encoder. I was able to use libx264.

(new FfmpegCommand('/input/path/to/file.avi')).videoCodec('libx264').format('mp4').save('/output/path/to/file.mp4')

doing getAvailableEncodes gives me lots of encoders, alongwith the one I'm trying to encode.
Yet i get this error: unknown decoder libx265.

const command = ffmpeg({ source: video.path });
  command.inputOptions([
    '-i',
    video.path,
    '-c:v',
    'libx265',
    '-crf',
    '23',
    '-tag:v',

    '1',
    '-color_trc',
    '1',
    '-colorspace',
    '1',
    '-movflags',
    '+faststart'
  ]);
  command.output(`${video.path}720.mp4`);

  command.on('progress', (progress) => {
    console.log(progress);
  });

  command.on('stderr', (errLine) => {
    console.log(errLine);
  });

  command.on('error', function(err, stdout, stderr) {
    console.log('Cannot process video: ' + err.message);
  });

  command.on('end', function(stdout, stderr) {
    console.log('Transcoding succeeded !');
  });

  command.run();

This is my code.

Please help me! I have explored every possible place i could find info.

Edit: more info:
doing ffmpeg.getAvailableCodecs() gives me the following codecs:

hevc: {

  }

this suggests me i have many codes for H265 encoing of videos.
And if i change my code slighly as follows:

command.inputOptions([
    '-i',
    video.path,
    '-c:v',
    'hevc',
    '-crf',
    '23',
    '-tag:v',
    'hvc1',
    '-pix_fmt',
    'yuv420p',
    '-color_primaries',
    '1',
    '-color_trc',
    '1',
    '-colorspace',
    '1',
    '-movflags',
    '+faststart'
  ]);

I have changed the codec to hevc, and then i didn't get the error anymore.
But now i get a new error as follows: Option movflags not found.

Cannot process video: ffmpeg exited with code 1: Option movflags not
found.

Any help will be appreciated..
