• ffmpeg 1.0.7 takes minute to create a thumbnail on "broken" video file but other files are seconds to create thumbnail

  8 juillet 2015, par Wiggler Jtag

  I’ve been using ffmpeg 1.0.7 for over 450GB (cca 400 files) for creating thumbnails and grabbing video-file information. It tooks me like 1-2 seconds to create 10 thumbnails from 8GB file. But now I’ve got some ’broken’ video file (672 MB) which creates me 1 thumbnail over a minute, 10 thumbnails its over 10 minutes -> my server burns :

   PID USER      PR  NI  VIRT  RES  SHR S  %CPU %MEM    TIME+  COMMAND
  
   9769 www-data  20   0  395m  28m 7212 R 157.0  0.4   0:04.99 ffmpeg

  I opened the file in Windows Media Player and getting blank screen while -> video file is weird, opened it in VLC and it wrote me : Because this AVI file index is broken or missing, seeking will not work correctly. VLC won't repair your file but can temporary fix this problem by building an index in memory. I’ve clicked ’Play as is’ and it plays the video file correctly, however my webserver burns because of FFmpeg and PHP waits for the return from exec(); command. Thumbnails are also created fine after 10 minutes, but how can I fix this problem or to prevent from executing FFmpeg for creating thumbnails on these broken ’video’ files ?

  This is my php :

  $cmd = "ffmpeg -i error.avi 2>&1";
  
  $info = `$cmd`;
  
  echo '<pre>';
  
  print_r($info);
  
  echo '</pre>';

  this is the output I am getting (very quickly)

  So it looks like just creating thumbnails is having problems :

  exec("ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");

  Where could be the problem ? Thanks for your suggestions !

  Btw. I am posting this on SO because I’m not sure where it belongs more than here - I think it could be done somehow by PHP but I’m not really sure.

  EDIT : I have added timeout, which "fixes" my problem, but even latest version of FFmpeg 2. stucks on creating thumbnail from broken video files.

  exec("timeout 5s ffmpeg -ss 01:11:43 -i error.avi -vframes 1 -s 616x320 -an output_1.jpg 2>&1");

• Added : Support for Chapter sub levels.

  5 octobre 2013, par Grandt

  Added : Support for Chapter sub levels.
  Rev. 2.53 - 2013-10-05
  
  * Added : Support for Chapter levels.
  
  * Added functions :
  
  *  ->subLevel() to indent one level under the current, additional
  
  chapters are added under that.
  
  *  ->backLevel() to step one level back to the parent of the current
  
  level.
  
  *  ->rootLevel() to step back to the root of the navMap.
  
  *  ->getCurrentLevel() to get the current level indentation (root = 1).
  
  *  ->setCurrentLevel(int) to set the current level indentation (1 or
  
  less returns to the root, same as ->rootLevel()).
  
  * ->buildTOC now reflects this level indentation if present.
  
  * ePub250 is otherwise compatible to the previous version, and no
  
  modifications are needed if you don't need this feature.

  I want to convert transmux ismv file to mp4 format. ISMV file is encoded withe the following ffmpeg detail :

   Encoder.mp4
