• PHP Run FFMPEG in background, and find out when it's done [closed]

  Run a ffmpeg process in the background

  I was wondering if there's any easy way to runn and ffmpeg process in the background so people can leave the page. And if you do that, then tell if the ffmpeg process is running, and when it's done, update the database to "finished". I'll post my code if I need to. Thanks !
  Here's the code on the processing page :

• Cannot find configure.ac file in ffmpeg

  23 février 2014, par Sudheesh

  Where can I find the configure.ac file of ffmpeg ?. I downloaded the latest version of ffmpeg from git, but couldn't find the configure.ac ( input for autoconf ).

  I am in the process of adding a new proprietary media encoding/decoding in ffmpeg. I plan to enable it via —enable-mylib ( like libfaac ). Hence the question.

• find text cointain in folder name and skip it's

  27 février 2014, par pasaico

  for subdir in */ ; do
  
  cd $subdir
  
  ffmpeg -i mycode

  how do I exclude the ffmpeg command if the folder name contains foo ?

  i use command find, is correctly ?

  find . -name *foo* -print

  but I can not implement it in bash for loop.

  I tried this code :

  for subdir in */ ; do
  
  foo=$(find -type d -name '*foo*')
  
  if [[ $subdir =~ $foo ] ; then
  
      echo yes
  
      ffmpeg -i mycode
  
  else
  
      echo no
  
  fi
  
  done
