• FFMPEG and Mencoder building screenshot returns 0 size images

  12 avril 2014, par Genus

  I have a script and it used to work fine but suddenly it stopped working and giving me zero size images as screenshot after video convert.

  here is the command for video screenshot.

  $cmd = $GLOBALS["paths"]["ffmpeg"]." -y -i ".$file." -f mjpeg -r 1 -ss ".$time." -vframes 1 -an ".$tmpdir."/00000001.jpg 2>&1";
  
      exec($cmd,$results);

  Debug :

• How to decode Full Rate GSM Audio file ?

  29 août 2012, par AndroidLearner

  I have to decode a full rate gsm audio file. Full Rate GSM Audio file is decoded using libgsm. I have used MSVC++ with windows nightly builds of ffmpeg and libav but unable to decode file correctly. Can anyone tell me the reason ? I have tried decoding using following codecs :
