• PHP : Video file is located in s3, need to find duration a video using getid3 php module

  14 mars 2019, par kaliyappan

      $request = $s3Client->createPresignedRequest($cmd, '+20 minutes');
  
      echo $presignedUrl = (string)$request->getUri();
  
  
  
      echo "\n";
  
      //$mp3File = '/home/kaliyappan/test-HD.mov';
  
      $getId3 = new GetId3();
  
      $audio = $getId3->analyze($presignedUrl);
  
      //echo '<pre>';
  
      print_r($audio);
  
      exit;
  
  </pre>

  I have a video file located in s3, using PHP "phansys/getid3" : "^2.1@dev" module need to calculate duration. Created pre-signed URL try to access that file but it returns "could not open that file".

  [GETID3_VERSION] => 1.9.4-20120530
  
  [error] => Array
  
      (
  
          [0] => Could not open "

  Please suggest any other way to do this, but if I directly give video file path which is in my server that’s work perfectly.

• ffmpeg-python extract a specific video stream, change its FPS and embed it back in the video

  19 mars 2021, par user972014

  I have a video containing several streams. A few data and one video.

  


  I need to extract the video stream, change the frame rate, embed it back in the video (or combine all stream back to an output file)

  


  If needed, this is the list of existing streams :

  


  I only need stream 0 and 5 (both video streams) Converted to 2 FPS. And stream 3 which is gpmd, which some irrelevant data format that I need to keep.

• How to overlay video on video with FFMPEG

  28 septembre 2021, par Yogas

  ihave 2 input video.mp4 (with audio) and notif.mov (with audio). I want to overlay notif.mov on video.mp4. I tried this code :

  


  ffmpeg -y -i video.mp4 -i "notif.mov" -filter_complex "[0:v][1:v]overlay=0:0" output.mp4

  


  both videos playing simultaneously, but sound missing from second input (notif.mov)

  


  Any tips ? Thank you !
