• ffmpeg not work with PHP exec()

  14 mars 2014, par user27133

  I need to convert video and create image using ffmpeg. I downloaded this package from zeranoe for windows 8 64x and put in c:/ffmpeg folder.

  I check for ffmpeg installed in windows using cmd : ffmpeg -version

  ffmpeg version N-60959-g669043d
  
  built on Feb 27 2014 22:07:15 with gcc 4.8.2 (GCC)

  lib
  
  libavutil      52. 66.100 / 52. 66.100
  
  libavcodec     55. 52.102 / 55. 52.102
  
  libavformat    55. 33.100 / 55. 33.100

  libswresample   0. 18.100 /  0. 18.100
  
  libpostproc    52.  3.100 / 52.  3.100

  Now I test convert video using php :

  $raw_video_path = 'C:\xampp\htdocs\video\ff\examples\5.flv';
  
  $new_flv = DIRNAME(DIRNAME(__FILE__)).'/ff/examples/video/2654.flv';
  
  $new_png = DIRNAME(DIRNAME(__FILE__)).'/ff/examples/video/2647-resampled.jpg';
  
  
  
  @exec("ffmpeg -i ".$raw_video_path."  -ab 56 -ar 44100 -b 200 -r 15 -s 320x240 -f flv ".$new_flv."");
  
  @exec("ffmpeg  -itsoffset -4  -i ".$new_flv." -vcodec mjpeg -vframes 1 -an -f rawvideo -s 320x240 ".$new_png." ");

  Now, This not work for me !! How do I can fix this ?

  For ffmpeg, I need to install/active php ffmpeg extension ?
