Live Video Facebook API with FFMPEG nodejs

Question

I have created Object Live Video as Facebook's document.

"stream_url": "rtmp://rtmp-api.facebook.com:80/rtmp/641310872699778?ds=1&a=AaYx3JYoFLTXAvBK"

I using https://github.com/fluent-ffmpeg/node-fluent-ffmpeg for stream but I failed.

Does anyone have solutions to stream video file (eg: mp4) to Object Video Facebook API?

var ffmpeg = require('fluent-ffmpeg'),
  fs = require('fs');

  // open input stream
var infs = fs.createReadStream(__dirname + '/2.mp4');

infs.on('error', function(err) {
  console.log(err);
});
var publish = "rtmp://rtmp-api.facebook.com:80/rtmp/641310872699778?ds=1&a=AaYx3JYoFLTXAvBK";
// make sure you set the correct path to your video file
var proc = ffmpeg(infs)

  .format('mp4')
  .size('320x?')
  .videoBitrate('512k')
  .videoCodec('libx264')
  .fps(24)
  .audioBitrate('96k')
  .audioCodec('aac')
  .audioFrequency(22050)
  .audioChannels(2)
  // setup event handlers
  .on('end', function() {
    console.log('file has been converted succesfully');
  })
  .on('error', function(err) {
    console.log('an error happened: ' + err.message);
  })
  // save to stream
  .save(publish); //end = true, close output stream after writing

an error happened: ffmpeg exited with code 1: rtmp://rtmp-api.facebook.com:80/rtmp/641310872699778?ds=1&a=AaYx3JYoFLTXAvBK: Operation not permitted

Answer 1

I got this error too when I tried to send an mp4 to a rtmp server. Convert the file to flv first because that is the file type that rtmp servers read and decode.

ffmpeg(infs).videoCodec('libx264').audioCodec('aac').toFormat('flv').save(publish)
