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

The filename of each file to read must contain a sequential number, |
|
|
|
|
which specifies the position of the file in the sequence. |

The pattern may contain the string "%d" or "%0@var{N}d", which |
|
|
|
|
specifies the position of the characters representing a sequential |
|
|
|
|
number in each filename matched by the pattern. If the form |
|
|
|
|
"%d0@var{N}d" is used, the string representing the number in each |
|
|
|
|
filename is 0-padded and @var{N} is the total number of 0-padded |
|
|
|
|
digits representing the number. The literal character '%' can be |
|
|
|
|
specified in the pattern with the string "%%". |
|
|
|
|
|
|
|
|
|
The first filename of the file sequence specified by the pattern must |
|

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

following numbers must be sequential. |

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

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

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

The pattern may contain a suffix which is used to automatically |

determine the format of the images contained in the files. |
