• ffmpeg - Live stream to web browser [on hold]

  21 octobre 2016, par Sreejith C M

  I was looking for a solution to stream my desktop live on my Windows system and found out ffmpeg is a good solution using dshow and everything is working fine and well. I’m using a C# wrapper for ffmpeg to record my desktop and I can save it in a local file.

  The problem I have is that, I have to watch the stream on my Web browser ( Chrome / Firefox ). I can’t use Media Server’s like wowza, red5 and also can’t use ffserver.

  I tried the ffmpeg wiki https://trac.ffmpeg.org/wiki and documentation but couldn’t figure out how to do this.

  Please help me to figure out this, how I can do this.

• ffmpeg horizonal flip makes video shorter

  26 mai 2020, par Adam Gosztolai

  I am trying to use the following command to flip my video horizontally

  



  ffmpeg -i video.mp4 -vf hflip -c:a copy video_flip.mp4


  



  However, I discovered that it makes the video shorter, which I did not intend.

  



  I originally created the video using FFMpegWriter in Python, the code looks something like this

  



  metadata = dict(title='video', artist='me', comment='Watch this!')
writer = FFMpegWriter(fps=25, metadata=metadata)
with writer.saving(fig, "video.mp4", 100):
    for t in range(100):
        ax.cla()        
        ax.plot(x,y)

        writer.grab_frame()


  



  What am I doing wrong ?

  


• 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.
