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.
