• FFMpeg + Beanstalk : How to pass the processes to it or achieve the same result without using Beanstalk

  6 avril 2017, par Ilia Rostovtsev

  My problem is that FFMpeg and Mencoder are extremely resourceful and running even one process of it makes HTTPd slow down but multiple processes of (FFMPEG /Mencoder) just hang it (HTTPd) completely. I would like my conversions to be processed with Beanstalk, for example.

  My concrete question is : How to transfer my current jobs to Beanstalk ?

  I have a simple PHP code that triggers conversion :

  RunInBackground('convert.php', array($upload, $video_id), $log_path);

  Now what would Beanstalk correct code would look like so these processes would NOT start all at the same time if multiple videos are uploaded ?

  If you believe that for my needs is better to use something else but Beanstalk and you know how to implement it, I would be still happy to see it !

  Thanks in advance,
  Ilia

• PHP shell_exec wait for script to done ? [duplicate]

  This question already has an answer here :

  • PHP shell_exec wait for script to finish ? [duplicate]

  I have a PHP script that queries a database for a list of jobs to be done and fires off other PHP scripts based on what it finds in the database (basically a process queue).

  Some of the scripts that the queue runner script executes may take 30 seconds or so to finish running (convert video, resizing images, etc).

  The problem is that shell_exec() in the queue runner script calls the processing scripts, but then doesn’t wait for them to finish, resulting in the queue not being completed.

  Queue runner script :

  #!/usr/bin/php
  
  <?php
  
      // Loop through database and find jobs to be done
  
      shell_exec("nohup $command > /dev/null 2> /dev/null & echo $! &");
  
  ?>

  Running the job script directly from the command line works and the PDF is created.

  Any ideas on how to fix this ? Or a better way to run a process queue ?

• How to make a videoplayer using FFmpeg on android ndk

  24 juillet 2012, par LMDS

  I'm trying to make a Video Player using ffmpeg and I use this tutorial http://dranger.com/ffmpeg/tutorial08.html, what I understand this tutorial convert a video to a video Image YUV, I'm trying to make the file that interact from .c to .java, I have this

  code c from the tutorial08(http://dranger.com/ffmpeg/tutorial08.c), then I made

  public class RtspReceiver extends Activity

  public SurfaceView sfv;
  
  @Override
  
  public void onCreate(Bundle savedInstanceState) {
  
      super.onCreate(savedInstanceState);
  
      setContentView(R.layout.principal);
  
      sfv=(SurfaceView) findViewById(R.id.im);
  
  }
  
  
  
  /* load our native library */
  
  static {
  
      System.loadLibrary("Interface");
  
  }
  
  
  
  private static native void Receive(SurfaceView  sf);

  In the c I'm trying to understand how I can use this

  JNIEXPORT void JNICALL isec_projecto_rtspreceiver_RtspReceiver_Receive(JNIEnv * env, jobject  obj, jobject Surface)
  
  {
  
  //what I have to put in here?
  
  }

  How can I put the SurfaceView that I have in the java, in the c ???
  and other thing, in the tutorial08.c how can I extract the video and put them in the java ? am I thinking correctly ?
