• stop or kill node media server

  9 juillet 2019, par user_66663333

  I am trying to implement stop feature for live video streaming using node-media-server.

  Basically I want to stop node-media-server completely, restart it later.

  const NodeMediaServer = require("node-media-server");
  
      let config = {
  
        logType: 3,
  
        rtmp: {
  
          port: rtmpPort,
  
          chunk_size: 60000,
  
          gop_cache: true,
  
          ping: 60,
  
          ping_timeout: 30,
  
        },
  
        http: {
  
          port: httpPort,
  
          allow_origin: "*",
  
        },
  
        relay: {
  
          ffmpeg: "/usr/bin/ffmpeg",
  
          tasks: [
  
            {
  
              app: "cctv",
  
              mode: "static",
  
              edge: "rtsp://" + cameraUrl + "/h264_ulaw.sdp",
  
              name: "uterum",
  
              rtsp_transport: "udp",
  
            },
  
          ],
  
        },
  
      };
  
  
  
      let nms = new NodeMediaServer(config);
  
      nms.run();

• Video player scroll doesn't work after ffmpeg audio and video merge (NodeJS)

  1er novembre 2022, par Pietro Leto

  I made youtube downloader to download video from youtube using nodejs library ytdl-core. If I wanted to download video with best quality I had to download them without sound. So, in my script, I download audio and video separately and I merge them into an mp4 file.
What's the problem ? Video player scroll doesn't work. I can see the video but I can't going back or move on, and I can't see video duration.

  


  const express = require("express");
const cors = require("cors");
const app = express();
const ffmpeg = require('ffmpeg-static');
const cp = require('child_process');
const ytdl = require("ytdl-core");

app.use(cors());

app.listen(3000, () => {
    console.log("Server is working at port 3000 !!");
});

app.get('/download', (req,res) => {
    var url = req.query.URL;
    var formato = req.query.FORMAT;

    try {
        let vid = ytdl(url,{filter:'videoonly', quality:'highestvideo'})
        let aud = ytdl(url, {filter: 'audioonly', quality:'highestaudio'});

        ytdl.getInfo(url).then(info => {
            titolo = info.videoDetails.title;

            res.header("Content-Disposition", 'attachment;  filename=' + titolo + '.mp4');

            const ffmpegProcess = cp.spawn(ffmpeg, [
                '-i', `pipe:3`,
                '-i', `pipe:4`,
                '-map','0:v:0',
                '-map','1:a:0',
                '-c:v', 'copy',
                '-c:a', 'aac',
                '-crf','27',
                '-preset','veryfast',
                '-movflags','frag_keyframe+empty_moov',
                '-f','mp4',
                '-loglevel','error',
                '-'
            ], {
                stdio: [
                'pipe', 'pipe', 'pipe', 'pipe', 'pipe',
                ],
            });
              
            aud.pipe(ffmpegProcess.stdio[4]);
            vid.pipe(ffmpegProcess.stdio[3]);
            ffmpegProcess.stdio[1].pipe(res);
        });
    }
    catch(err) {
        console.log("Error with URL: " + url + "\nERROR: " + err + "\n\n");
    }
});


  


  I have not found alternatives to do this. I need a working script to download youtube videos with good quality.

  


• Is there a way to batch save video information (frame height, width, rate, etc) to video files' metadata ? [closed]

  6 avril 2021, par André Levy

  Searched all over to no avail. I had a vague recollection that MediaInfo did it, but no can do. Perhaps there's a way with ffmpeg, but all I've seen are commands to export the metadata already on the files.
