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.
