NAME

       yuvinactive - Set a part of the video to a defined state

SYNOPSIS

       yuvinactive [options] </dev/stdin >/dev/stdout

DESCRIPTION

       yuvinactive  operates with a area (rectangle) you define.  By default is sets it to really black. But you
       can tell tell yuvinactive to darken the area, or fill it with a certain  color.  It  can  also  make  the
       content  of  the  area unreadable, like extreme softening of the area.  Or copy the surrounding area into
       the the specified area.  You usually have to use the -i option which sets the area in  which  yuvinactive
       will  work.  If no additional option is given yuvinactive stet the area to black.  But you can use the -d
       -s -a -c options to tell yuvinactive that it shall do something different with that area.  You  can  only
       use one additional option. yuvinactive was built to remove unwanted things like a logo, from the movie.

OPTIONS

       lav2yuv accepts the following options:

       -h   Some help output

       -iXxY+XOFF+YOFF
            Specifies the area yuvinactive shall work with. With this option the area is set to black. There are
            no restrictions because of interlacing.

       -d num
            How much darker the area should be compared to the original color.  This is done by setting a  lower
            value for the luma. The value is in percent from the original luma.

       -s num
            Here you specify a certain color in the yuv format.

       -a num
            With  this  option the program uses on pixel and averages the surrounding pixels with the same color
            to make the original less readable.  The number tells the the program how  much  pixels  around  the
            original pixel should be overwritten with the same color. You have to use a even number here

       -c num
            Sets  the  number of surrounding pixels yuvinactive should use to copy them into the given area. You
            have to use a even number here. yuvinactive uses the lines above and below the  specified  area  for
            copying them into the area.

BUGS

       Right,  there are bugs hidden. The thing is not well tested, and not every option might work. yuvinactive
       is in the first state of becoming a useful program.
