  af_hdcd : disable auto-convert by default
  As all known valid HDCD sample formats and sample rates are now handled
  
  by the filter, remove the scan that "invades the privacy" of the filter graph
  
  and turn off autoconvert by default as requested by Nicolas George.

• Invalid data found when processing input using FFmpeg for extracting video thumbnail

  3 octobre 2016, par Simer

  I am using below command to extract thumbnail from

  'C:\ffmpeg\bin\ffmpeg -i '.$server_public_path.'\frontend\videos\gallery\user_'.$logged_in_user_id.'\\' .$video_name.' -ss 00:00:30.435 -vframes 2 -flags +global_header '.$server_public_path.'\frontend\videos\gallery\user_'.$logged_in_user_id.'\\thumbnails\\'.$video_name;

  where $server_public_path is absolute path of my project. Above command working fine when I used it on some other path and video.

  Below is the error I am getting :
