• FFMPEG Drag and Drop sh file

  29 avril 2021, par WFCDefi

  On Windows I have a simple batch file which I drop video files onto to convert to webms, it saves a lot of time as I prefer to just use the same configuration and don't care much about the names.

  


  @echo off 
echo. 
ffmpeg -i %1 -c:v libvpx-vp9 -quality good -cpu-used 2 -b:v 5000k -qmin 15 -qmax 45 -maxrate 500k -bufsize 1500k -framerate 60 -threads 8 -vf scale=-1:1080 -c:a libvorbis -b:a 192k -f webm %1.webm 
pause


  


  I know the .bat file won't really work in Linux (I'm on pop os so pretty much Ubuntu) so with the other lines removed and the %1 changed to $1 it works. It won't do anything if I try dragging and dropping a video file onto it though.

  


  I can type sudo then drag and drop the .sh file followed by a video into a terminal and press enter and it will have the same effect as dragging a video file onto a bat file in Windows.

  


  Is there a way to recreate dragging and dropping a file directly onto another and it executing in Linux or is the terminal the only way ?

  


• Php - Get video duration from a file hosted on amazon S3 server

  8 mai 2017, par Michael Lee

  I am developing back-end API with php to get the duration from a video file hosted on amazon S3. The API server is hosted on amazon EC2 and the video file is uploaded on amazon S3. The problem is when I request to API server, it has to response the information of the video file hosted on amazon S3 such as duration, file size, resolution etc. At least, it must response the video. I’ve followed codes by using ffmpeg such as below, but it’s not working.

  <?php
  
  $file = 'https://videoapptest-bucket.s3.amazonaws.com/video/10/44__55_f03876434e48d5fed7d6982b0cf578de_u_00000.ts';
  
  $result = shell_exec('ffmpeg -i ' . escapeshellcmd($file) . ' 2>&1');
  
  preg_match('/(?<=Duration: )(\d{2}:\d{2}:\d{2})\.\d{2}/', $result, $match);
  
  print_r($match);
  
  ?>

  How can I get the video duration from a file hosted on amazon s3 with ffmpeg or another tool ?

• Anomalie #2855 : mauvais traitement du signe par textwheel

  9 août 2014, par cedric -

  Coquille dans le test, corrigée par http://zone.spip.org/trac/spip-zone/changeset/84111
  Si on dit que les < doivent être échappés dans la mesure du possible, le patch suivant semble faire le boulot sans casser aucun autre test.
  Mais est-ce que ça en vaut vraiment la peine ?
