  6 septembre 2021, par Amir Shahzad

  This is nodejs server side file

  


  const express = require('express');
const ffmpeg  = require('fluent-ffmpeg');
const fileUpload = require('express-fileupload');
const mongoose = require('mongoose');
const cors   = require('cors')
const app = express();
const Video = require('./models/video');
mongoose.connect('mongodb://localhost:27017/YoutubeApp', {
    useNewUrlParser: true,
    useUnifiedTopology: true,
});
const db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error'));
db.once('open', () => {
   console.log('Data Base Connected Successfully!');
});

app.use(fileUpload({
   useTempFiles: true,
   tempFileDir: 'temp/'
}));
app.use(express.json());
app.use(express.urlencoded({ extended: true }));
app.use(cors({ origin: 'http://localhost:4200' }));


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

app.post('/mp4tomp3', (req, res) => {
  convertdata = req.body;
  console.log('path of innput is', req.body);
  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.code, err.msg);
              callback(err);
           }).run();
      }
     convert(convertdata, './temp/output.mp3', function(err){
        if(!err) {
          console.log('conversion complete');

 
     }
 })

 app.listen(3000, () => {
    console.log('Server Start On Port 3000')
 })


  


  In Convert function i not know how i can get input by the user i'm new in angular Please anyone can solve this out thanks in advance

  


  This is video model file

  


  const mongoose = require("mongoose");
const Schema = mongoose.Schema;

const videoSchema = new Schema({
    mp4: String,
});
module.exports = mongoose.model("Videos", videoSchema);


  


  **This is Typescript code in angular client side that handle user input and select video **

  


  import { ThrowStmt } from '@angular/compiler';
import { Component, OnInit } from '@angular/core';
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
import { VideoConversionService } from 'src/services/video-conversion.service';

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent implements OnInit {

   submitted =false;
   form! : FormGroup
   data:any

   constructor(private formBuilder: FormBuilder,
       private videoService: VideoConversionService){}

   creatForm(){
    this.form = this.formBuilder.group({
    mp4: ['', Validators.required],
  });
  }
   ngOnInit(): void {
   this.creatForm();

  }


  convertVideo(){
    this.submitted = true
    this.videoService.conversion(this.form.value).subscribe(res => {
    this.data = res;
 })
 }

 }


  


  I do not know how to create logic to do that (convert video into audio using angular framework)

  


  This is app.component.html file where i want to get video from the user using input field

  


  <div class="container">&#xA;   <h1>Video Proccessing App</h1>&#xA;   <form>&#xA;     <input type="file" formcontrolname="mp4" />&#xA;     <input type="submit" value="Convert" />&#xA;  </form>&#xA;</div>&#xA;

  


  


  But my code is not working and video is not converting into audio

  


  This is my video service file where i calling nodejs api to perform the task

  


  import { Injectable } from '@angular/core';
import { HttpClient  } from '@angular/common/http';
@Injectable({
   providedIn: 'root'
})
export class VideoConversionService {

constructor(private httpClient: HttpClient) { }

conversion(data: any){
   return this.httpClient.post('http://localhost:3000/mp4tomp3', data)
}
}


  


  Please anyone can solve my problem Thanks in advance

• How to configure ffmpeg for streaming videos from Red5 into Youtube using youtube-v3-api ?

  28 mai 2018, par Alfonso Valdes

  You’ll see my problem is next :

  Currently I’m working to configure youtube-v3-api for live streaming of .flv videos on my Youtube channel using Red 5 service as stated on next link https://www.red5pro.com/docs/server/ffmpegstreaming.html, this is using next commands for streaming on Linux :

  ffmpeg  -i rtmp://127.0.0.1:1935/live/streamname live=1 timeout=2 -vcodec libx264 -s 640x480 -vb 500k -acodec libfdk_aac -ab 128k  -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}
  
  
  
  
  
  ffmpeg -rtsp_transport tcp -i rtsp://127.0.0.1:8554/live/streamname -acodec copy -vcodec copy -f flv rtmp://a.rtmp.youtube.com/live2/{Stream name/key}

  On this, neither RMTP nor RTSP protocols are working for streaming. Also, I have tried several codecs for audio and video configuring different sizes for each one of them, but none of those have worked.

  The root streaming videos are generated by an IOS/Android app still on development phase.

  The problem comes when no video is displayed on Youtube screen, regardless the video is being sent by Red5 (I confirmed this on my Red5 dedicated server on AWS) and received correctly by Youtube (confirmed by validating on Console), so I have come into a dead end on which I hope you could help me get through.

  Any idea of what could be a possible solution ?

  Thank you.
