• How to display multiple rtmp streams from Gryphon nginx ?

  22 août 2018, par LoukMo

  CONTEXT :

  -I received a rtsp stream link from an onvif ip camera.

  -The camera can only host 5 streaming connection at a time (I want/need more connections).

  -I’ve been informed that a combination of ffmpeg (to convert the rtsp stream to rtmp) and nginx (to redistribute as many streams as I want) would do what I want.

  -I’m on Windows 10.

  -I downloaded ffmpeg from this source and nginx from this source (nginx 1.7.11.3 Gryphon.zip).

  -Here’s the conf file of the nginx server :

  user nobody;
  
  worker_processes 1;
  
  
  
  events {
  
    worker_connections  1024;
  
  }
  
  
  
  rtmp {
  
          server {
  
                  listen 1935;
  
                  chunk_size 4096;
  
  
  
                  application live {
  
                          live on;
  
                          record off;
  
                  }
  
          }
  
  }

  -I’m using this command to push my camera’s stream to the nginx server :

  ffmpeg -hide_banner -i "rtsp://user:password123@192.168.10.116:554/videoMain" -an -f flv -rtmp_live live "rtmp://127.0.0.1:1935/live"

  -I can then see the output stream using vlc’s open network stream tool (rtmp ://127.0.0.1:1935/live)

  QUESTION :

  Is there a way to have multiple input/outout streams at the same time ?

  I want to have multiple cameras redirected at the same time by one server...

  

• Setting up RTP on Nginx

  2 février 2021, par Swap

  I'm trying to use Janus Media Server to relay WebRTC streams to a particular RTP host/port, from where ffmpeg can pick it up as an input and convert it further to an rtmp stream, which can then be used to broadcast to various social media platforms (such as, YouTube, Twitch, Facebook, etc.)

  


  My inspiration for this has been the following blog - https://www.meetecho.com/blog/firefox-webrtc-youtube-kinda/

  


  Specifically, I'm trying to replicate the following architecture -

  


  

  


  And Janus, as per their documentation, has a very neat API for doing it -

  For this, I've setup a Nginx server, where I've also installed Janus and everything's been running smoothly so far. But I'm quite clueless as to how to setup my Nginx server so that it accepts RTP connections (which will be forwarded as RTMP using ffmpeg).

  


  Please guide me to any relevant resources that would help me achieve this. Thanks in advance !

  


• Show portrait video to landscape on Videojs player as HLS ffmpeg Laravel

  11 décembre 2020, par TwistCode

  I am currently using the ffmpeg library through laravel sdk. For the landscape videos I have no problem with the scaling filters application, but with the portrait videos I need the video to look like the thumbnail below :

  


  

  


  But when I play the video, the player is distorted.

  


  

  


  Note : It should be noted that when I work with horizontal scales, the player looks good, but the video is distorted.

  


  

  


  

  


  this is my PHP Laravel code implementation

  


              FFMpeg::FromDisk('local')->open($this->media)
            ->exportForHLS()
            ->setSegmentLength(6) // optional
            /*
            ->addFormat($lowBitrate, function ($media) {
                $media->addFilter(function ($filters, $in, $out) {
                    $filters->custom($in, 'scale=854x480,setsar=1,setdar=16:9', $out); // $in, $parameters, $out

                });
            })*/
            // Portrait test
            ->addFormat($lowBitrate, function ($media) { 
                $media->addFilter(function ($filters, $in, $out) {
                    // $filters->custom($in, "scale='w=min(720,trunc((480*33/40*dar)/2+0.5)*2):h=min(480,trunc((704*40/33/dar)/2+0.5)*2)',pad='w=720:h=480:x=(ow-iw)/2:y=(oh-ih)/2',setsar='r=40/33'", $out); // $in, $parameters, $out
                    $filters->custom($in, "scale=239:-1", $out); // $in, $parameters, $out
                });
            })
            /*
            ->addFormat($midBitrate, function ($media) {
                $media->scale(1280, 720);
            })
            ->addFormat($highBitrate, function ($media) {
                $media->scale(1920, 1080);
            })*/
            ->save("public/hls/$video->id/$video->hash_name.m3u8");


  


  This is the command that runs at the server level for portrait videos.

  I don't really know if my problem is at the server or frontend level, but I would greatly appreciate any contribution.
