• FTP Video Upload and Thumbnail Rotation Issue

  25 juin 2018, par Bits Please

  I am uploading video using ffmpeg command. I am then creating then thumbnail. I want to rotate video, how can I achieve this ?

  Here is my Code :

      $thumbnail_name =  preg_replace('"\.(mp4|avi|flv|vob|oggg)$"', '.jpg', $newfilename);
  
  
  
  $movie = "/home/foldername/public_html/master/assets/user_videos/".$newfilename;
  
  
  
  $thumbnail = "/home/foldername/public_html/master/assets/user_videos/".$thumbnail_name;
  
  
  
  $command = '/usr/bin/ffmpeg -y -ss 00:00:01 -i '.$movie.' -f image2 -vframes 1 '.$thumbnail.' 2>&1';

• Calling ffmpeg from subprocess.run and refering to specific directory

  27 décembre 2018, par Akalyn

  I’m trying to compile images contained in a given directory D into an mp4 video from a python script. I decided to use ffmpeg and hence called it through
  subprocess.run().

  When I issue the following command from another directory than D :

  ffmpeg -framerate 30 -pattern_type glob -i 'path/to/D/*.jpg' -vcodec libx264 -y movie.mp4

  it works fine.

  The same thing happens when I issue the command from the python script with the shell=True option :

  subprocess.run(" ".join(["ffmpeg", "-framerate", "30", "-pattern_type", "glob", "-i", "'path/to/D/*.jpg'", "-vcodec", "libx264", "-y", "movie.mp4"]), shell=True)

  However I know that relying on shell=True is not recommended. I tried using subprocess.run without that option :

  subprocess.run(["ffmpeg", "-framerate", "30", "-pattern_type", "glob", "-i", "'path/to/D/*.jpg'", "-vcodec", "libx264", "-y", "movie.mp4"])

  but it resulted in the following error :

  'path/to/D/*.jpg': No such file or directory.

  Why does the call to ffmpeg fail when calling it through subprocess.run with shell=False option ?

• ffprobe failed to execute command

  31 août 2020, par Ted Bed

  I'm trying to get a frame from a video in a temp location but I get an error like this :

  


  Uncaught Alchemy\BinaryDriver\Exception\ExecutionFailureException: ffprobe failed to execute command '/usr/bin/ffprobe' '/tmp/phpfwEh9u' 


  


  Which is weird because I have another script that does the exact same thing but there is no error. Are there any reasons for why this could be happening ? Could there be any factors causing this in my script :

  


  $sec = 1;
$movie =  $filentmpname;
$thumbnail = 'thumbnail_uploads/' . $imfileid;

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($movie);
$frame = $video->frame(FFMpeg\Coordinate\TimeCode::fromSeconds($sec));
$frame->save($thumbnail);
