Fluent-ffmpeg "not a suitable output format"

I'm using the fluent-ffmpeg module for Node.js to convert audio files. I have a .mp3 file that I'd like to convert to .wma

Here's what that looks like:

var proc = new ffmpeg({
   source: 'file.mp3',
   nolog: false
}).toFormat('wma')                                                
  .saveToFile('file.wma', function(stdout, stderr)
{                                                 
    console.log(stderr);
});

Unfortunately, I get the error:

Requested output format 'wma' is not a suitable output format

This is the entire error log:

I know this isn't an ffmpeg issue because

ffmpeg -i file.mp3 file.wma

Works fine. Any ideas?

this worked for me fine

fluent_ffmpeg('input.mp3').audioCodec("aac").save('output.aac')

when formats was: D aac raw ADTS AAC (Advanced Audio Coding)

not E = Muxing supported

I think, wma is not a container format. It is an audio codec. WMA file is most commonly contained in ASF (Advanced Systems Format) format. So choose the correct options as given in the fluent-ffmpeg API to set codec and the format. You can run these commands:

  1. ffmpeg -formats to see all formats and

  2. ffmpeg -codecs to see all supported codecs
