This demuxer reads from a list of image files specified by a pattern.

  27
  
  
    
The filename of each file to read must contain a sequential number,


  		




  28
  
  
    
which specifies the position of the file in the sequence.


  		




  29
  
  
    

  		




  30
  
  
    
The pattern must contain the string "%d" or "%0@var{N}d", which


  		




  31
  
  
    
specifies the position of the characters representing the seqential


  		




  
  27
  
    
The pattern may contain the string "%d" or "%0@var{N}d", which


  		




  
  28
  
    
specifies the position of the characters representing a sequential


  		




  32
  29
  
    
number in each filename matched by the pattern. If the form


  		




  33
  30
  
    
"%d0@var{N}d" is used, the string representing the number in each


  		




  34
  31
  
    
filename is 0-padded and @var{N} is the total number of 0-padded


  		




  35
  32
  
    
digits representing the number. The literal character '%' can be


  		




  36
  33
  
    
specified in the pattern with the string "%%".


  		




  37
  34
  
    

  		




  38
  
  
    
The first filename of the file sequence specified by the pattern must


  		




  39
  
  
    
contain a number inclusively contained between 0 and 4, all the


  		




  40
  
  
    
following numbers must be sequential.


  		




  
  35
  
    
If the pattern contains "%d" or "%0@var{N}d", the first filename of


  		




  
  36
  
    
the file list specified by the pattern must contain a number


  		




  
  37
  
    
inclusively contained between 0 and 4, all the following numbers must


  		




  
  38
  
    
be sequential. This limitation may be hopefully fixed.


  		




  41
  39
  
    

  		




  42

The pattern may contain a suffix which is used to automatically


  		




  43
  41
  
    
determine the format of the images contained in the files.

Note that the pattern must not necessarily contain "%d" or


  		




  
  61
  
    
"%0@var{N}d", for example to convert a single image file


  		




  
  62
  
    
@file{img.jpeg} you can employ the command:

@example


  		




  
  64
  
    
ffmpeg -f image2 -i img.jpeg img.png
