• 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.

  


• FFMPEG : Add a offset in the Scene Change Detection

  17 mai 2019, par steph

  I am trying to add a frame offset(o) in ffmpeg scene detection filter :

  For example : ...filter:v "select='gt(scene,X) generates frame 10, 34, 300.

  I looking for a new construction with o=10 generates frame 20, 44, 310...

  Thank you for help !
