• ffplay does not play an RTMP stream on VM with Ubuntu

  7 novembre 2020, par PiotrKulesza

  I am trying to run my RTMP stream on a VM with Ubuntu installed. The stream starts on the host computer from the obs program.

  


  Obs stream settings :

  


  Server: rtmp://192.168.56.102:1935/show
Stream key: stream


  


  Obs sends the stream to the nginx server on the VM with Ubuntu installed.

  


  RTMP configuration in nginx.conf

  


  rtmp {
    server {
        listen 1935; # Listen on standard RTMP port
        chunk_size 4000;

        application show {
            live on;
            # Turn on HLS
            hls on;
            hls_path /mnt/hls/;
            hls_fragment 3;
            hls_playlist_length 60;
            # disable consuming the stream from nginx as rtmp
            deny play all;
        }
    }
}


  


  When I start the stream it connects because it shows up in netstat.

  


  Output from netstat :

  


  Active Internet connections (w/o servers)
Proto Recv-Q Send-Q Local Address           Foreign Address         State      
tcp        0      0 webapp-VirtualBox:1935  192.168.56.1:56924      ESTABLISHED


  


  But when I try to play stream with ffplay, it doesn't work. I am getting the following error.

  I have tried the following commands to play a stream but each one gives the same error.

  


  ffplay -i rtmp://192.168.56.102:1935/show/stream
ffplay -i rtmp://webapp-VirtualBox:1935/show/stream
ffplay -i rtmp://localhost:1935/show/stream


  


  I also tried VLC but this program also didn't work.
Can anyone tell me what I am doing wrong or forgot to play this stream ?

  


• Why won’t this mp4 play in a video-js tag any longer

  18 octobre 2019, par Velocedge

  I’m using ffmpeg to convert files to MP4. I’ve made some modifications to the ffmpeg string but now it seems no matter what I use, the video won’t play in an HTML5 tag (Chrome browser). Normally, I just used "-vcodec libx264 -s 1280x720 -ar 22050". When I try to load it in the video tag, I get the following error on http://family.gotsport.net/lmw/GotSport/videoPlayer.asp?WS=1&URL=/VideoFiles/2/4_70_highlight :

  The media could not be loaded, either because the server or network failed or because the format is not supported.

  No matter what parameters I use (or don’t use), it still won’t play. However, if you just call the url directly, it will play in Chrome (http://family.gotsport.net/videofiles/2/2_70_highlight.mp4). I’m using the 7.0.0 version of video-js from their CDN (although older versions give the same result).

  Video tag looks like :

  <video class="video-js vjs-default-skin" autoplay="autoplay" controls="controls" preload="auto"> 
  
      <source src="/VideoFiles/2/4_70_highlight.mp4" type="video/mp4"></source>
  
  </video>

  Do you see anything that would keep this format from playing in an HTML5 video tag ?

• Able to get HLS to play on VLC viewer but not on browser

  6 mai 2022, par Tamothee

  so i have been trying to get ipcamera to connect to a react app and show live video. i found and followed this tutorial https://www.youtube.com/watch?v=-a5MAaEaizU&t=185s .

  


  i am able to get vlc viewer to run the hls server link and display what the camera sees. however when i plug the link into my code or a browser hls viewer like https://hls-js.netlify.app/demo/ , the m3u8 link does not play. there is no error and when i inspect the network, i do receive the m3u8 and .ts links.
this is what i see on the network portion

  


  ffmpeg -i rtsp://admin:Password1234@192.168.1.64:554/Streaming/Channels/101 -fflags flush_packets -max_delay 2 -flags -global_header -hls_time 2 -hls_list_size 3 -vcodec copy -y ./index.m3u8


  


  this is the ffmpeg command that i ran to convert my rtsp output to hls.

  


  var http = require('http');
var fs = require('fs');

const port = 1234

http.createServer(function (request, response) {
console.log('request starting...');

var filePath = '.' + request.url;

fs.readFile(filePath, function(error, content) {
    response.writeHead(200, { 'Access-Control-Allow-Origin': '*' });
    if (error) {
        if(error.code == 'ENOENT'){
            fs.readFile('./404.html', function(error, content) {
                response.end(content, 'utf-8');
            });
        }
        else {
            response.writeHead(500);
            response.end('Sorry, check with the site admin for error: '+error.code+' ..\n');
            response.end(); 
        }
    }
    else {
        response.end(content, 'utf-8');
    }
});

}).listen(port);
console.log(`Server running at http://127.0.0.1:${port}/`);


  


  this is the code for the hls server that receives the request and sends the user the m3u8 and ts files.

  


   


  


  and i'm trying to play the link like this using react-hls-player

  


  hope this is not a stupid question as i'm a beginner and hope that someone could help me with this problem.
