• ffmpeg convert video in a path with different name

  16 mars 2019, par tour travel

  Using ffmpeg in php with shell_exec and want to convert video in a path that different with where script is run. php script is in /s/m/video.php :

  <?php
  
  if(isset($_GET["videoTools"])){
  
  
  
      $user = $_GET["user"];
  
      $uid = $_GET["uid"];
  
      $vid = $_GET["vid"];
  
  
  
      $uploaddir = '/seller/uploads/'.$user.'/'.$uid.'/';
  
  
  
      echo shell_exec('ffmpeg -i '.$uploaddir.$vid.'-vid.mp4 -i /s/m/logo.png \
  
      -filter_complex "hflip[flipped];[flipped]overlay=x=20:y=20" \
  
      -s 480x320 -acodec aac -strict -2 -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 \
  
      -strict -2 '.$uploaddir.$vid.'-vid-resized.mp4');
  
  }
  
  ?>

  And this script called by ajax in /s/a/index.php :

      $.ajax({
  
          url: "/s/m/video.php?videoTools",
  
          type: "GET",
  
          data: {vid: json[0], uid: json[1], user: json[2]},
  
          success: function(data){
  
           // success
  
          }
  
      });

  And for example I want to convert video in this path /s/uploads/91/768/2019-2-2_668-vid.mp4

  Problems :

  This not working, because look like ffmpeg not find video and logo in a path / Also look like ffmpeg not accepet video with - or _ or etc.

  No related error log, but video not generated and script not working. Any idea ?

• FFMPEG video merging. Only first video shows

  13 mars 2019, par James Ashworth

  I’m trying to put 7 second intro video before another one, but I keep having trouble with it. I don’t need to do anything else then add intros to videos.

  This is what I’m currently getting.

  It shows the 7 second video as the whole video. Someway i got it to change after 7 seconds, but then the rest of the video was really buddy.
