• Windows 2003 using php popen "start /b" because of executing ffmpeg.exe

  1er juillet 2013, par Oh Seung Kwon

  I have some problem.

  There is a php code that convert audio(wav) to mp3 file with using ffmpeg.exe.

  Here is some code.

  $cmd = "./inc/ffmpeg.exe -i ".$file_name." -acodec mp3 -y -ac 1 -ab 96k ".$mp3_file_name;
  
  
  
  echo $cmd;
  
  echo "Windows";
  
  $handle = popen("start /B ".$cmd, "r");
  
  while(!feof($handle)) {
  
      $read = fread($handle, 2096);
  
      echo $read;
  
  }
  
  pclose($handle);

  Problem is when I execute this code, ffmpeg.exe process isn't terminated. And not gonna die when I stop process with using Windows task manager.

  Do you have a solution for this situation ?

• Streaming live video from ios

  12 février 2014, par John

  I have a need to stream video from the iPhone/iPad camera to a server. It looks like this will need to be done with AVCaptureSession but I don't know how to best architect this.

  I found this post :

  streaming video FROM an iPhone

  But it doesn't handle the "live" part, latency needs to be 2 or 3 seconds at most. Devices can be constrained to 4 or 4S capability if needed, and there is no requirement for HD, VGA is probably what we'll end up with. I assume any solution would use ffmpeg, I haven't found any more appropriate library.

  How is this best accomplished ?
