• Two rtsp streams to youtube on a Pi3

  19 mars 2020, par Sébastien Bonaimé

  I want to stream two rtsp camera from my birdbox to youtube from my raspberry pi 3 with the entrance in Pip (picture in picture) on top left. I don’t need sound.

  192.168.1.13 can do 30 fps with sound that I don’t need
  192.168.1.31 is only 12 fps without sound

  I have some problems of lag between the two camera on the youtube stream which I think is due to the different fps. I compile ffmpeg with h264. Here is what I did

  ffmpeg -re -f lavfi -i anullsrc -rtsp_transport udp -thread_queue_size 1000k -i rtsp://admin:123@192.168.1.13:554 -i rtsp://admin:@192.168.1.31:554 -filter_complex "[1]scale=iw/4:ih/4[pip]; [2][pip] overlay=0:0"   -framerate 13  -bufsize 512k  -b:v 1500k -threads 4 -q:v 3  -c:v h264_omx  -c:a aac -f flv rtmp://a.rtmp.youtube.com/live2/XXX-XXXX-XXX

  and here are the errors

  [h264 @ 0x20ddd30] error while decoding MB 69 67, bytestream -6rate=1589.2kbits/s dup=0 drop=6 speed=0.997x

  What can I do to improve the stream ? When a bird enter the box, there is also a quality problem when the image is changing and some lagging.

• Can't obtain thumbnail with ffmpeg codeigniter

  2 avril 2015, par DMBorges

  I have used the following tutorial ( https://www.youtube.com/watch?v=qT4hN5o57hI) to try to obtain a thumbnail from a uploaded video using codeigniter as a framework. As I am new to all this I don’t understand if at the end of supposedly uploading my video the code failed to create a thumbnail, if my created thumbnail is somewhere lost in my computer of by some settings reasons ffmpeg is not working.

  Where does my $imageFile goes to ?

  Here is my code.

  MY VIEW

  <div>
  
  
  
              &lt;?php echo form_open_multipart('gallery/save/'); ?>
  
                  <table class="table">
  
                      <tr>
  
                          <td>Video</td>
  
                          <td>&lt;?php echo form_upload('pic'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td>Descrição</td>
  
                          <td>&lt;?php echo form_input('description'); ?></td>
  
                      </tr>
  
                      <tr>
  
                          <td></td>
  
                          <td>&lt;?php echo form_submit('upload', 'Guardar', 'class="btn btn-primary"'); ?></td>
  
                      </tr>       
  
                  </table>
  
  
  
      </div>

• 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.
