• ffmpeg : i cant make tee working for restreaming

  24 avril 2018, par Jorge Vértiz

  I’ve been trying to overlay an image on a rtmp stream and resend it to Facebook Live and Twitch, using a nginx with a rtmp module and ffmpe. I have used this code for each service :

  ffmpeg -i rtmp://localhost/app/streamkey -i logo.png -filter_complex "[0:v][1:v] overlay=0:0" -c:v libx264 -preset veryfast -bufsize 4000k -c:a aac -b:a 160k -ar 44100  -f flv rtmp://live-api.facebook.com:80/rtmp/streamkey;

  I have one command for Facebook Live and another for Twitch, but it consumes much hardware, so looking around I found a work around using tee seudo-mixer :

  ffmpeg -i rtmp://localhost/app/streamkey -i logo.png -filter_complex "[0:v][1:v]overlay=10:10" -c:v libx264 -preset veryfast -bufsize 4000k -c:a aac -b:a 160k -ar 44100  -f tee "[f=flv]rtmp://live-api.facebook.com:80/rtmp/streamkey|[f=flv]rtmp://live-jfk.twitch.tv/app/streamkey"

  It works fine with Facebook Live, but when Twitch starts the live streaming there is no image, only a black screen.

  What am I doing wrong, and how do I get this stream working ?

• How can upload audio on dropbox after converted it from the video format using ffmpeg in nodejs and angular

  21 septembre 2021, par Amir Shahzad

  nodejs server side code

  


  This is my nodejs server side where i want to convert the video into the audio format and then want to upload the converted audio on the dropbox is there any way to do that ??

  


  const express = require('express'),
path = require('path'),
cors = require('cors'),
ffmpeg = require('fluent-ffmpeg'),
fs = require("fs"),
access_token = "My-Access-Token";

ffmpeg.setFfmpegPath('/usr/bin/ffmpeg');

const app = express();
app.use(cors());
app.use(express.json());
app.use(express.urlencoded({
  extended: false
}));


app.post('/api/upload', upload.single('mp4'), function (req, res) {
  if (!req.file) {
    console.log("No file is available!");
    return res.send({
     success: false
  });

  } else {
   function convert(input, output, callback) {
      ffmpeg(input)
          .output(output)
          .on('end', function() {                    
           console.log('conversion ended');
            callback(null);
          }).on('error', function(err){
           console.log('error: ', err);
            callback(err);
          }).run();
    }
     const filepath = req.file.path;
     var content = fs.readFileSync(filepath);

 options = {
    method: "POST",
    url: 'https://content.dropboxapi.com/2/files/upload',
    headers: {
     "Content-Type": "text/plain; charset=dropbox-cors-hack" ,
     "Authorization": "Bearer " + access_token,
      "Dropbox-API-Arg": "{\"path\": \"/youtube- 
       radio/"+req.file.originalname+"\",\"mode\": \"overwrite\",\"autorename\": 
       true,\"mute\": false}",
    },
     body:content
};
convert(filepath,  options+'.mp3', function(err,res, body){
   if(!err) {
    console.log('File Name is',req.file.originalname);
    console.log('File Path Is = ',req.file.path)
    console.log('conversion complete');   
    console.log('ERR', err);
   }
});
console.log('File is available!');
return res.send({
  success: true
})
}
 });


  const PORT = process.env.PORT || 8080;
  const server = app.listen(PORT, () => {
  console.log('Connected to port ' + PORT)
  })
