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 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:

       <filename_without_extension>_x.<picture_extension>

       Where x starts with 0 and is incremented with every created thumbnail. So  the  thumbnails
       are  successively  numbered by the appearance 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 commas. 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 commas. 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 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 mysecondfile.ogv
