• connecting with IP camera using opencv

  19 septembre 2022, par Smadar

  I have a proVisionISR IP camera which I am trying to connect through openCV.videoCapture().
I have inserted RTSP URL like this : "rtsp ://user:password@IP:port/", I also tried to add different ending after the port in the URL, such as profile2 which indicate on the sub stream (pic below),
H264 ?ch=1&subtype=0 and more results I found while searching.
The code uses cv2.CAP_FFMPEG, but tried also with GSTREAMER pipeline.

  


  I changed some values in the camera dashboard configuration, such as resolution that fit the code, the encoding also was changed to h264, and disabling the audio as well. (The bitrate type is : CBR)

  


  I open the stream in VLC, and it is work just fine. And 2 more IP cameras with RTSP streaming was able to connect with : cv2.videocapture(RTSP URL, cv2.CAP_FFMPEG)

  


  Python version : 3.8
OpenCV version : 4.6.0-dev (installed from source)
ffmpeg version 4.2.7
ubuntu version (If necessary) 20.04

• FFMPEG fails to run using exec() or shell_exec() in PHP

  17 août 2015, par Richard Kriesman

  So I’ve been working on trying to get FFMPEG to encode videos that are uploaded to my site. The upload script calls the PHP binary using exec() to run a script called encode.php that looks like this :

  include("include/config.inc.php");
  
  $videoID = $argv[1];
  
  exec("ffmpeg -i " . $_SERVER['DOCUMENT_ROOT'] . "/processing/" .  $videoID. ".mp4 -vcodec libx264 -vpre normal -s 1280x720 -r 30 -acodec libfaac " . $_SERVER['DOCUMENT_ROOT'] . "/videos/" . $videoID . ".mp4");
  
  $connect = mysql_connect($dbhost, $dbusername, $dbpassword);
  
  mysql_select_db($dbname, $connect);
  
  $query = mysql_query("UPDATE `videos` SET `isProcessing` = 0 WHERE `id` = '$videoID' LIMIT 1");

  However, nothing happens to the video at all. I’ve tried using the full path to FFMPEG, but that doesn’t work either. I know the script is being executed as the isProcessing is set to 0 in the database.

  Maybe I’m just clueless, but I can’t seem to figure this out. Any help would be greatly appreciated.

• Evolution #3674 : Chaine de traitement dans la table des traitements

  27 février 2016, par Fil _

  La bonne syntaxe en l’état actuel des choses serait :

  ```
  ’LOGO_EVENT’ =>
  array (size=1)
  0 => string ’massicoter_logo(logo_par_defaut(%s), $connect, event, $Pile<sup>1</sup>[’id_event’])’ (length=xx)

  ```

  c’est un `array` mais seulement parce que la valeur pour 0 est le filtre générique, et qu’on peut spécialiser avec d’autres clés comme par exemple ’TEXTE’. Pour le moment on n’"empile" pas les filtres (j’avoue que je n’y avais jamais pensé, c’est peut-être une bonne idée d’évolution).

  En attendant ton plugin peut faire quelque chose comme :
  `filtre = str_replace(’%s’, $filtre, ’’massicoter_logo(%s, $connect, event, $Pile<sup>1</sup>[’id_event’]" )`
