• Windows FFMPEG will not find my files at all [migrated]

  22 mars 2014, par user2441247

  I have a folder full of images that go from 0 to whatever number, and I need to turn these images to a video. They are all .PNG files. Here is my command I am using :

  ffmpeg.exe -f image2 -framerate 30 -pattern_type sequence -start_number 1 -r 30 -i "img%%04d.jpg" -s 1280x720 test.avi

  When I run this I get this error :

  [image2 @ 002be580] Could find no file with path 'img%04d.jpg' and index in the range 1-5
  
  
  
  img%04d.jpg: No such file or directory

  What can I change to get this to work ?

• 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

  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 !
