• How to read data from subprocess pipe ffmpeg without block in line when rtsp is disconnected

  22 août 2024, par Jester48

  I have some problems with the ffmpeg subprocess in python where I open an RTSP stream.
One of them is the long time of reading a frame from the pipe, I noticed that reading one frame takes about 250ms -> most of this time is the select.select() line which can take just that long. This makes opening the stream above 4FPS problematic. When I do not use the select.select function, the reading speed is normal, but when the connection to RTSP streams is lost, the program gets stuck in the self.pipe.stdout.read() function and does not exit from it. Is it possible to protect yourself in case of missing data in pipe.stdout.read() without losing frame reading speed as in the case of select.select() ?

  


  class RTSPReceiver(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)
        self.ffmpeg_cmd = ['ffmpeg','-loglevel','quiet','-rtsp_transport' ,'tcp','-nostdin','-i',f'rtsp://{config("LOGIN")}:{config("PASS")}@{config("HOST")}/stream=0','-fflags','nobuffer','-flags','low_delay','-map','0:0','-r',f'{config("RTSP_FPS")}','-f','rawvideo','-pix_fmt','bgr24','-']
        self.img_w = 2688
        self.img_h = 1520
        self.image = None
        self.pipe = subprocess.Popen(self.ffmpeg_cmd, stdout=subprocess.PIPE)

    def reconnect(self) -> None:
        if self.pipe:
            self.pipe.terminate()
            self.pipe.kill()
            self.pipe.wait()

    def run(self) -> None:
        self.connect()
        while True:
            try:
                ready, _, _ = select.select([self.pipe.stdout], [], [], 15.0)
                if ready:
                    raw_image = self.pipe.stdout.read(self.img_w*self.img_h*3)
                    if raw_image:
                        with self.lock:
                            self.image = np.frombuffer(raw_image, dtype=np.uint8).reshape(self.img_h, self.img_w, 3)
                else:
                    self.reconnect()
            except Exception as e:
                self.connect()


  


• how to use ffmpeg to get thumbnails from a video

  23 mai 2017, par okendo

  I have been trying over weeks now to figure out how to use ffmpeg to get thumbnail from a video while upload that video in php.
  This is my code and I don’t where I went wrong please help.

  <?php
  
  if (logged_in() === true) {
  
      if (isset($_POST['up'], $_FILES['file'])) {
  
          $file_name = $_FILES['file']['name'];
  
          $file_type = explode('.', $file_name);
  
          $file_type = strtolower(end($file_type));
  
          $random    = rand();
  
          $file_tmp  = $_FILES['file']['tmp_name'];
  
  
  
      $file_dir = "jobalertme/includes/video_uploads/$random.$file_type";
  
      if ($file_type == 'mp4' || $file_type == 'avi' || $file_type == 'wmv' || $file_type == 'mov' || $file_type == 'flv') {
  
          if (move_uploaded_file($file_tmp, "$file_dir")) {
  
              $ffmpeg    = "C:\\ffmpeg\\bin\\ffmpeg";
  
              $img_name  = "1.jpg";
  
              $img_size  = "120x90";
  
              $getimgsec = 5;
  
              $cmd       = "$ffmpeg -i $file_tmp -an -ss $getimgsec -s $img_size  www/jobalertme/includes/img_thumnail/$img_name <br />";
  
              if (shell_exec($cmd)) {
  
                  echo "ok";
  
              } else {
  
                  echo "not";
  
              }
  
  
  
  
  
              $updat = "UPDATE registration SET video='$file_dir' WHERE uname='$username'";
  
              $qry   = mysqli_query($con, $updat);
  
              if ($qry) {
  
                  echo "<code class="echappe-js">&lt;script&gt; alert('your file has been successfully uploaded ')&lt;/script&gt;
  " ;
  
                  echo "&lt;script&gt;window.open('upload_vid.php','_self')&lt;/script&gt;" ;
  
                  exit() ;
  
               else 
  
                  echo "&lt;script&gt; alert('we ran into some problems')&lt;/script&gt;" ;
  
                  echo "&lt;script&gt;window.open('upload_vid.php','_self')&lt;/script&gt;" ;
  
                  exit() ;
  
              
  
           else 
  
              echo "&lt;script&gt; alert('we ran into some problems')&lt;/script&gt;" ;
  
              echo "&lt;script&gt;window.open('upload_vid.php','_self')&lt;/script&gt;" ;
  
              exit() ;
  
          
  
       else 
  
          echo "&lt;script&gt;alert('please this file extension is not allowed, it must be an mp4 file format')&lt;/script&gt;" ;
  
          echo "&lt;script&gt;window.open('upload_vid.php','_self')&lt;/script&gt;" ;
  
          exit() ;
  
      
  
  
  
   else 
  
      echo "
  
  &lt;script&gt;alert('please you need login before you can upload resume.')&lt;/scrpt&gt;&quot;;<br />
  
      echo &quot;&lt;script&gt;window.open('upload_vid.php','_self')&lt;/script&gt;
  " ;
  
      exit() ;
  
  
  
   ?>
  
  
  

  I have search on google youtube and others but still have not gotten the solution.
