• nginx rtmp ubuntu18.04 ffmpeg transcode problem

  26 septembre 2020, par Muhammet Halit Parlak

  I installed nginx rtmp on ubuntu 20.04, but somehow I could not run ffmpeg. Previously it was working in ubuntu 12.04.

  


  exec ffmpeg -i http://iptvle-platinum.dyndns-server.com:80/live/YQbNcng9Iu/HzZ15vbJzN/57835.ts -codec copy -bsf:v h264_mp4toannexb -f mpegts udp ://51.77.148.186:2555 ;

  


• I have a problem with node js rtsp streaming server

  11 décembre 2022, par sangeun jo

  I made rtsp cctv streaming server with nodjs.

  


  But it is not stable.

  


  Some cctvs works well but others are not.

  


  First I thought rtsp url has its own problem, but it may not.
Because the url worked well in vlc player.

  


  I don't know what I'm missing.

  


  below is my whole code related cctv streaming.

  


  


  


  var express = require('express');
var router = express.Router();
var kill  = require('tree-kill');
var fs = require('fs');
var path = require('path');

var ffmpeg = require('fluent-ffmpeg');
var ffmpegInstaller = require('@ffmpeg-installer/ffmpeg');
ffmpeg.setFfmpegPath(ffmpegInstaller.path)

var streams = {};

//start cctv
router.post('/', (req, res) => {

  var cname = req.body.cname;
  var url = req.body.url;

  //if there is same cctv name
  if(streams[cname] != null) {
    res.status(409).send("duplicate name");
    return;
  };

  //create dir as given cctv name;
  mkdir(cname);

  stream = ffmpeg(url).addOptions([
    '-hls_time 5', 
    '-hls_list_size 10',
    '-hls_flags delete_segments',
    '-f hls' 
  ]).output('./public/video/' + cname + '/'  + cname + '.m3u8'); //save path

  console.log("Start cctv streaming");
  stream.on('error', function(err, stdout, stderr) {
    console.log("cctv has been stoped");
    console.log(err);
  });

  stream.run(); 

  streams[cname] = stream;
  res.status(201).send("OK");
});

//bring cctv pid by cctv name
router.get('/:cname', (req, res) => {
  var cname = req.params.cname;

  if(streams[cname] == null) {
    res.status(404).send("not found such a cctv");
    return;
  };

  var pid = streams[cname].ffmpegProc.pid;
  res.send({"pid": pid});
});


//stop cctv by pid 
router.delete('/:cname', async (req, res) => {
  var cname = req.params.cname;
  
  //no cctv
  if(streams[cname] == null) {
    res.status(404).send("not found such a cctv");
    return;
  };


  //del dir
  var filePath = './public/video/' +  cname;
  fs.rmdir(filePath, { recursive: true }, (err) => {
    if (err) {
      console.log(err)
    } else {
      console.log('dir is deleted.');
    }
  });

  //var pid = streams[cname].ffmpegProc.pid;
  streams[cname].kill();
  res.status(204).send("OK");
});

const mkdir = (name) => {
  var root = './public/video/';
  if(!fs.existsSync(root + name)){
    fs.mkdirSync(root + name);
  }
}

  


  


  



  And this is ts file save folder.
cctv1 dosen't work well but cctv2 works well.
(cctv1 started first but created less ts file than cctv2.)
