• How to send output stream from ffmpeg into a servlet

  12 mai 2016, par Antonio Mele

  I am trying to get the video stream from an ip camera in my network and redirect it to a servlet.

  Using this command to get the video and redirect the output to standard output

  avconv -f mjpeg -y -i 'http://USER:PASSWORD@192.168.1.5/video.cgi' -r 3 -loglevel 16 -c:v mjpeg -an -qscale 10 -f mp4 -

  Then I would like to call this from a java servlet using ProcessBuilder and sending the streaming to servlet output. So when I will open it from the browser I will get the video streaming.

  I am trying to do this to be able to encode the video as I prefer and to be able to call my web server from Internet to access any camera in my network and avoid to have a port forwarding or nat for every camera.

  If you have any suggestions for other solutions to expose my camera outside my local network having only my public ip (without having to configure my router) are well accepted :)

  thank you

• Want to send webcam stream to wowza using ffmpeg

  20 octobre 2015, par Ivan Orozco

  I am new to both Wowza and to FFMPEG. I have been testing with ffmpeg and I am able to create local files with video and audio. For example :

  ffmpeg -f dshow -i video="HD Pro Webcam C920" myvideo.mpeg
  
  
  
  ffmpeg -rtbufsize 1500M -f dshow -i video="HD Pro Webcam C920":audio="Microphone (Parallels Audio Con" -pix_fmt yuv420p myvideoandaudio.mp4

  What I want to do is send the stream of my webcam to the Wowza server I have installed locally. I have searched several forums, including this one, and have tried multiple commands but still no luck. I would like to have someone point me in the right direction. Following Wowza’s instructions, I created a Stream File called mystream, which has a stream UI of udp ://0.0.0.0:10100. Also, the application connection settings say that the server’s IP is 10.160.XX.XXX and port 1935. I am using Windows, and the "Shared" version of the FFMPEG downloads. I even changed the XML file following the instructions here, trying to send user credentials (during installation, Wowza asked to create credentials if I was going to use streaming) :

• look for an mp4 file inside a directory and send it to different directory after converting to mp3 in php ?

  13 mai 2019, par flash

  I have a directory called incoming_folder in which there is an mp4 file.

  What I want to achieve through php code is to scan a incoming_folder directory, look for an mp4 file and send it to outgoing_folder after converting it into mp3. Technically outgoing_folder should have mp3 version of mp4 from incoming_folder

  Tried with the following code although its scanning the incoming_folder directory but no conversion is happening through ffmpeg.

  <?php
  
  $dir    = 'in_folder';  /* Place where mp4 file is present */
  
  $files1 = scandir($dir);
  
  print_r($files1);    /* It lists all the files in a directory including mp4 file*/
  
  
  
  $destination = 'out_folder';  /* Place where mp3 file need to be send after conversion from mp4 */
  
  
  
  foreach($files1 as $f)
  
  {
  
    $parts = pathinfo($f);
  
  
  
    switch($parts['extension'])
  
    {
  
      case 'mp4' :
  
        system('ffmpeg -i '.$f.' -map 0:2 -ac 1 '.$destination.DS. $parts['filename'].'.mp3', $result);
  
  
  
        if ($result) {
  
          // Do something with result if you want
  
          // log for example
  
        }
  
        break;
  
  
  
      case 'mp3' :
  
        // copy($f, $destination. DS . $parts['filename']. '.' . $parts['extension']);
  
        copy($f, $destination.DS.$parts['filename'].'.mp3');
  
        break;  
  
    }
  
  }
  
  ?>
