• How to execute fluent-ffmpeg commands from express router ?

  27 janvier 2021, par Chris

  so I'm trying to control and m3u8 playlist using data sent in thru an express route and keep getting the same error "Error : ffmpeg exited with code 1 : Conversion failed !" when attempting.

  


  My code looks like this

  


  ch1Router
    .route("/source")
    .post(jsonBodyParser, (req, res, next) => {
        //video url from request body
        const { url } = req.body;
        
        //test console log
        console.log(req.body);

        //ffmpeg commands
        ffmpeg(url)
            .output('videos/Ch1.m3u8')
            .on('error', (err) => {
                console.log("Something Happened:", err.message)
                res.send("Error changing input!")
            })
            .run()
            

        
        res.send("hi")
    })


  


  When I run this exact command in a separate file using Node, the command executes and I only need to refresh my browser to see the new video file. When trying to chain it to a post request containing the video URL I get the conversion error. Any help would be appreciated.

  


  **Updated my code to prevent the server from crashing and respond with an error message but still don't understand the conversion error.

  


• Send rtmp from nginx into another VM

  12 janvier 2018, par Akim Benchiha

  I’ve set up my nginx server in a VM for the rtmp connection.
  I want to use exec_push for running a script in another VM.

  NGINX 1st VM

  rtmp {
  
    server {
  
       listen 1935;
  
       ping 30s;
  
       notify_method get;
  
          application ingest {
  
               live on;
  
               exec_kill_signal term;
  
               idle_streams off;
  
               #exec_push /usr/local/bin/ffmpeg_push.sh $name ;
  
               exec_options on;
  
               exec_push sshpass -p PASSWORD ssh root@192.168.1.139 sh /usr/local/bin/ffmpeg_push.sh $name;
  
       }
  
    }
  
  }

  I have also tried with node server that execute the script but every time, the script reset

  NGINX 1st VM

     rtmp {
  
        server {
  
           listen 1935;
  
           ping 30s;
  
           notify_method get;
  
              application ingest {
  
                   live on;
  
                   exec_kill_signal term;
  
                   idle_streams off;
  
                   #exec_push /usr/local/bin/ffmpeg_push.sh $name ;
  
                   exec_options on;
  
                   exec_push curl -X POST -H "Content-Type: application/json" -d "" 192.168.1.139:3000/$name;
  
           }
  
        }
  
      }

  NodeJS into second VM

  #!/usr/bin/env node
  
  
  
  const express = require('express');
  
  var app = express();
  
  app.use(function (req, res, next) {
  
          res.setHeader('Access-Control-Allow-Origin', '*');
  
          res.setHeader('Access-Control-Allow-Methods', 'GET, POST, OPTIONS, PUT, PATCH, DELETE');
  
          res.setHeader('Access-Control-Allow-Headers', 'X-Requested-With,content-type');
  
          res.setHeader('Access-Control-Allow-Credentials', true);
  
          next();
  
  });
  
  app.post('/:name', function(req, res) {
  
          console.log('start performed');
  
          console.log(req.params.name);
  
          require('child_process').spawn('sh', ['ffmpeg_push.sh', req.params.name], {stdio: 'inherit'});
  
  });

  But when the script is running in the first VM, everything is fine. I have disabled the firewall.
  Thank you.

• How to download .ism files protected by DRM (Widevine or IIS Smoth Streaming)

  16 septembre 2019, par Foopy7774

  I’m struggling to download a video which is protected by DRM or something else (idk)...I tried to download it by using VLC, ismdownloader, ffmpeg and youtube-dl but the video seems encrypted. There bound to be a way to do it, given that Chrome is able to read it...

  I’ve seen that they are using Widevine or IIS Smooth Streaming, I don’t really know...but if you can’t answer my post, can you atleast set me on the right path by telling me :
  What they use ? Widevine ? IIS Smooth Streaming ? Both ?
