• Remove some redundant NULL checks and fix a free on error return.

  3 mars 2012, par Tim Terriberry

  Remove some redundant NULL checks and fix a free on error return.
  ref_frame_data was being allocated with the aligned allocator, but
  
   freed with the normal _ogg_free() function on failure, which
  
   doesn’t work.
  
  This would only cause a problem if there was just enough memory to
  
   satisfy the reference frame allocation (just over 4.5 or 9 bytes
  
   per pixel) but not enough for the fragment buffer offets (1/16 or
  
   1/8th byte per pixel).

• PHP - FFMPEG - Unable to apply multiple regular expressions on media output

  9 avril 2012, par Parth G

  I am writing a php script (I have to use php) to cycle through a dir of media files and displaying media information in a chart.

  Right now, I'm trying to do it on 1 file.

  I can successfully do so. I currently can parse the output (using regular expressions) to obtain information such as file name, duration, resolution, etc

  I was told that I can combine the regular expressions to make it more efficient.

  When I do however, I am unable to parse the ffmpeg output correctly.

  Consequently, I've tried copying the output to a string and parsing that using multiple expressions and it works just fine.

  Any help is appreciated.

  Thanks.

  New Code

  I tried using the ffmpeg-php extension and the following works (except for printing the bit rate)

  $movie = new ffmpeg_movie($video_file);
  
  
  
  echo $movie->getFilename();
  
  echo "<br />" ; 
  
  echo $movie->getDuration();
  
  echo "<br />" ;
  
  echo $movie->getFrameWidth();
  
  echo "x";
  
  echo $movie->getFrameHeight();
  
  echo "<br />" ; 
  
  echo $movie->getBitRate();
  
  echo "<br />" ; 
  
  echo $movie->getVideoBitRate();
  
  echo "<br />" ; 
  
  echo $movie->getAudioBitRate();
  
  echo "<br />" ;
  
  echo $movie->getVideoCodec();
  
  echo "<br />" ;
  
  echo $movie->getAudioCodec();
  
  ?>
