       oggThumb	- creates thumbnails from an ogg video file

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

       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	series 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:


       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.

       -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 incrementally.

	      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
	      throughout  the  different  videos, so that the pictures are not

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

	      Example: -n myNo_%_thumb

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