NAME
     oggThumb - creates thumbnails from an ogg video file

SYNOPSIS
     oggThumb [options] file1.ogv [ file2.ogv [ file3.ogv [...] ] ]

DESCRIPTION
     oggThumb  creates	Thumbnails  from one or more ogg video files, at a given
     time position or a given frame number. It is also possible to create a  se-
     ries  of  thumbnails at different time or frame positions. The pictures can
     be created in JPG or PNG format and can be resized to any given size.

     The default naming of each thumbnail series follows the following rule:

     <filename_without_extension>_x.<picture_extension>

     Where x starts with 0 and is incremented with every created  thumbnail.  So
     the  thumbnails  are  successivly numbered by the appearence order. This is
     even valid, if time positions and frame numbers are mixed.

OPTIONS
     -t     Time at which a thumbnail should be created. More than one thumbnail
	    time can be concatenated by komas. The times can be set  by  integer
	    or	floating  point  values  in  seconds. If the time is not exactly
	    matching, the next frame is used. The times don't have to be  sorted
	    incrementally.

	    Example: -t 12.4,14.157,13.23

     -f     Number  of	a frame that should be created as a thumbnail. More than
	    one thumbnail frame can be concatenated by komas. The frame  numbers
	    must  be  an integers. The frame numbers don't have to be sorted in-
	    crementally.

	    Example: -f 12000,13000,11000

     -s     Picture output size. The thumbnail is created in the size  given  as
	    <width>x<height>.	If  you want to include the thumbnails into your
	    webpage and you need to have a fixed width but dynamic  height,  you
	    can  set  the  dynamic  axis  to 0. So the aspect ratio of the video
	    frame is kept. This is the same for setting width or height to 0.

	    Example: -s 0x100

     -o     Output format. This can be png or jpg. The default is jpg.

	    Example: -o png

     -n     Alternative thumbnail picture name. The % can  be  used  within  the
	    name to indicate the counter placeholder.

	    In case of more than one video file, the counter continuous through-
	    out the different videos, so that the pictures are not overwritten.

	    If the name has an extension. This extension is used to identify the
	    output picture format.

	    Example: -n myNo_%_thumb

EXAMPLE
     oggThumb -t 10.3,22.4,31.9,43.4,59.4 -f 1200 -s 0x100 myFile.ogv

     oggThumb  -f  200,400,300,100  -t	3.54 -n %_thumb.png myfile.ogv mysecond-
     file.ogv
