  avcodec/libjxldec : fix gamma22 and gamma28 recognition
  Gamma 2.2 and Gamma 2.8 are tagged in the file as 0.45455 and 0.35714,
  
  respectively (i.e. 1/2.2 and 1/2.8). Trying to identify them as 2.2 and
  
  2.8 instead of these values will cause the transfer function to not
  
  properly be recognized. This patch fixes this.

• regex for files recognition for ffmpeg command

  10 avril 2015, par Vishal Desai

  I’m trying to use ffmpeg command to create a time-lapse from a bunch of images in a folder. The images are named in the format -
  folder_number ;timestamp.jpg
  eg,
  0 ;1423116000.jpg
  0 ;1423137600.jpg

  I run the following command,

  ffmpeg -i %*.jpg -q:v 2 output.mpeg

  the video is getting formed but it is a 30seconds video with only the first image in the folder.

  I only assume the regex i’m using - %*.jpg is wrong. Please help.

  ps : I’m newbie to ffmpeg
