• Anomalie #2003 (Nouveau) : calculer_select, jointures complexes

  25 février 2011, par Jean-Jacques Puig

  Bonjour, J’ai observé un dysfonctionnement dans les recherches sur des données traitées par le plugin forms_and_tables_2_0 ; cependant, je rapporte ce problème ici car il ne me semble pas évident que la correction doive se faire du côté de ce plugin. Le problème vient d’une combinaison du critère (...)

• 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 ?

• With ffmpeg print onto clipped video hh:mm:ss time *from original* and hh:mm:ss total duration from original

  25 mai 2023, par Kes

  I am using arch linux and bash and ffmpeg, all are up to date and the latest versions.

  


  I am clipping a video that is 30 seconds long and wish to clip from 5 secs to 10 seconds to a new file, from the original.

  


  In the bottom right hand corner of the clip I wish to show timestamps from the original video as follows

  


  

  • in the 5th second "00:00:05/ 00:00:30"

  


  • in the 6th second "00:00:06/ 00:00:30"
    
etc

  


  • in the 10th second "00:00:10/ 00:00:30"

  


  


  This is an apparentley simple question(?) but the syntax of the command is not at all obvious and I am hoping an expert may shed some light on this.

  


  All I have so far for the drawtext part, which does not do what I want as it only counts the elapsed time from t=0 of the new clip, whereas I want it to show the timestamp and total duration of the original clip

  


  drawtext I started with

  


  "drawtext=text='%{pts\:gmtime\:0\:%M\\\\\:%S}':fontsize=24:fontcolor=black:x=(w-text_w-10):y=(h-text_h-10)"


  


  ffmpeg line with drawtext I have started with

  


  ffmpeg -ss 00:00:05 -i  "$in_file" -filter_complex "drawtext=fontfile=font.ttf:text='sample text':x=10:y=10:fontsize=12:fontcolor=white:box=1:boxcolor=black@0.5:boxborderw=5,drawtext=text='%{duration\:hms}':fontsize=12:fontcolor=black:x=(w-text_w-10):y=(h-text_h-10)" -t 5 -c:a copy -c:v libx264 out_file.mp4
