-@chapter Introduction
-
-@var{Please be aware that vhook is deprecated, and hence its development is
-frozen (bug fixes are still accepted).
-The substitute will be 'libavfilter', the result of our 'Video Filter API'
-Google Summer of Code project. You may monitor its progress by subscribing to
-the ffmpeg-soc mailing list at
-@url{http://lists.mplayerhq.hu/mailman/listinfo/ffmpeg-soc}.}
-
-The video hook functionality is designed (mostly) for live video. It allows
-the video to be modified or examined between the decoder and the encoder.
-
-Any number of hook modules can be placed inline, and they are run in the
-order that they were specified on the ffmpeg command line.
-
-The video hook modules are provided for use as a base for your own modules,
-and are described below.
-
-Modules are loaded using the -vhook option to ffmpeg. The value of this parameter
-is a space separated list of arguments. The first is the module name, and the rest
-are passed as arguments to the Configure function of the module.
-
-The modules are dynamic libraries: They have different suffixes (.so, .dll, .dylib)
-depending on your platform. And your platform dictates if they need to be
-somewhere in your PATH, or in your LD_LIBRARY_PATH. Otherwise you will need to
-specify the full path of the vhook file that you are using.
-
-@section null.c
-
-This does nothing. Actually it converts the input image to RGB24 and then converts
-it back again. This is meant as a sample that you can use to test your setup.
-
-@section fish.c
-
-This implements a 'fish detector'. Essentially it converts the image into HSV
-space and tests whether more than a certain percentage of the pixels fall into
-a specific HSV cuboid. If so, then the image is saved into a file for processing
-by other bits of code.
-
-Why use HSV? It turns out that HSV cuboids represent a more compact range of
-colors than would an RGB cuboid.
-
-@section imlib2.c
-
-This module implements a text overlay for a video image. Currently it
-supports a fixed overlay or reading the text from a file. The string
-is passed through strftime() so that it is easy to imprint the date and
-time onto the image.
-
-This module depends on the external library imlib2, available on
-Sourceforge, among other places, if it is not already installed on
-your system.
-
-You may also overlay an image (even semi-transparent) like TV stations do.
-You may move either the text or the image around your video to create
-scrolling credits, for example.
-
-The font file used is looked for in a FONTPATH environment variable, and
-prepended to the point size as a command line option and can be specified
-with the full path to the font file, as in:
-@example
--F /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf/20
-@end example
-where 20 is the point size.
-
-You can specify the filename to read RGB color names from. If it is not
-specified, these defaults are used: @file{/usr/share/X11/rgb.txt} and
-@file{/usr/lib/X11/rgb.txt}
-
-Options:
-@multitable @columnfractions .2 .8
-@item @option{-C <rgb.txt>} @tab The filename to read RGB color names from
-@item @option{-c <color>} @tab The color of the text
-@item @option{-F <fontname>} @tab The font face and size
-@item @option{-t <text>} @tab The text
-@item @option{-f <filename>} @tab The filename to read text from
-@item @option{-x <expression>}@tab x coordinate of text or image
-@item @option{-y <expression>}@tab y coordinate of text or image
-@item @option{-i <filename>} @tab The filename to read a image from
-@item @option{-R <expression>}@tab Value for R color
-@item @option{-G <expression>}@tab Value for G color
-@item @option{-B <expression>}@tab Value for B color
-@item @option{-A <expression>}@tab Value for Alpha channel
-@end multitable
-
-Expressions are functions of these variables:
-@multitable @columnfractions .2 .8
-@item @var{N} @tab frame number (starting at zero)
-@item @var{H} @tab frame height
-@item @var{W} @tab frame width
-@item @var{h} @tab image height
-@item @var{w} @tab image width
-@item @var{X} @tab previous x coordinate of text or image
-@item @var{Y} @tab previous y coordinate of text or image
-@end multitable
-
-You may also use the constants @var{PI}, @var{E}, and the math functions available at the
-FFmpeg formula evaluator at (@url{ffmpeg-doc.html#SEC13}), except @var{bits2qp(bits)}
-and @var{qp2bits(qp)}.
-
-Usage examples:
-
-@example
- # Remember to set the path to your fonts
- FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
- FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
- FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
- export FONTPATH
-
- # Bulb dancing in a Lissajous pattern
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.dll -x W*(0.5+0.25*sin(N/47*PI))-w/2 -y H*(0.5+0.50*cos(N/97*PI))-h/2 -i /usr/share/imlib2/data/images/bulb.png' \
- -acodec copy -sameq output.avi
-
- # Text scrolling
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.dll -c red -F Vera.ttf/20 -x 150+0.5*N -y 70+0.25*N -t Hello' \
- -acodec copy -sameq output.avi
-
- # Date and time stamp, security-camera style:
- ffmpeg -r 29.97 -s 320x256 -f video4linux -i /dev/video0 \
- -vhook 'vhook/imlib2.so -x 0 -y 0 -i black-260x20.png' \
- -vhook 'vhook/imlib2.so -c white -F VeraBd.ttf/12 -x 0 -y 0 -t %A-%D-%T' \
- output.avi
-
- In this example the video is captured from the first video capture card as a
- 320x256 AVI, and a black 260 by 20 pixel PNG image is placed in the upper
- left corner, with the day, date and time overlaid on it in Vera Bold 12
- point font. A simple black PNG file 260 pixels wide and 20 pixels tall
- was created in the GIMP for this purpose.
-
- # Scrolling credits from a text file
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.so -c white -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
- -sameq output.avi
-
- In this example, the text is stored in a file, and is positioned 100
- pixels from the left hand edge of the video. The text is scrolled from the
- bottom up. Making the y factor positive will scroll from the top down.
- Increasing the magnitude of the y factor makes the text scroll faster,
- decreasing it makes it scroll slower. Hint: Blank lines containing only
- a newline are treated as end-of-file. To create blank lines, use lines
- that consist of space characters only.
-
- # Scrolling credits with custom color from a text file
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.so -C rgb.txt -c CustomColor1 -F VeraBd.ttf/16 -x 100 -y -1.0*N -f credits.txt' \
- -sameq output.avi
-
- This example does the same as the one above, but specifies an rgb.txt file
- to be used, which has a custom-made color in it.
-
- # Variable colors
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.so -t Hello -R abs(255*sin(N/47*PI)) -G abs(255*sin(N/47*PI)) -B abs(255*sin(N/47*PI))' \
- -sameq output.avi
-
- In this example, the color for the text goes up and down from black to
- white.
-
- # Text fade-out
- ffmpeg -i input.avi -vhook \
- 'vhook/imlib2.so -t Hello -A max(0,255-exp(N/47))' \
- -sameq output.avi
-
- In this example, the text fades out in about 10 seconds for a 25 fps input
- video file.
-
- # scrolling credits from a graphics file
- ffmpeg -sameq -i input.avi \
- -vhook 'vhook/imlib2.so -x 0 -y -1.0*N -i credits.png' output.avi
-
- In this example, a transparent PNG file the same width as the video
- (e.g. 320 pixels), but very long, (e.g. 3000 pixels), was created, and
- text, graphics, brushstrokes, etc, were added to the image. The image
- is then scrolled up, from the bottom of the frame.
-
-@end example
-
-@section ppm.c
-
-It's basically a launch point for a PPM pipe, so you can use any
-executable (or script) which consumes a PPM on stdin and produces a PPM
-on stdout (and flushes each frame). The Netpbm utilities are a series of
-such programs.
-
-A list of them is here:
-
-@url{http://netpbm.sourceforge.net/doc/directory.html}
-
-Usage example:
-
-@example
-ffmpeg -i input -vhook "/path/to/ppm.so some-ppm-filter args" output
-@end example
-
-@section drawtext.c
-
-This module implements a text overlay for a video image. Currently it
-supports a fixed overlay or reading the text from a file. The string
-is passed through strftime() so that it is easy to imprint the date and
-time onto the image.
-
-Features:
-@itemize @minus
-@item TrueType, Type1 and others via the FreeType2 library
-@item Font kerning (better output)
-@item Line Wrap (put the text that doesn't fit one line on the next line)
-@item Background box (currently in development)
-@item Outline
-@end itemize
-
-Options:
-@multitable @columnfractions .2 .8
-@item @option{-c <color>} @tab Foreground color of the text ('internet' way) <#RRGGBB> [default #FFFFFF]
-@item @option{-C <color>} @tab Background color of the text ('internet' way) <#RRGGBB> [default #000000]
-@item @option{-f <font-filename>} @tab font file to use
-@item @option{-t <text>} @tab text to display
-@item @option{-T <filename>} @tab file to read text from
-@item @option{-x <pos>} @tab x coordinate of the start of the text
-@item @option{-y <pos>} @tab y coordinate of the start of the text
-@end multitable
-
-Text fonts are being looked for in a FONTPATH environment variable.
-If the FONTPATH environment variable is not available, or is not checked by
-your target (i.e. Cygwin), then specify the full path to the font file as in:
-@example
--f /usr/X11R6/lib/X11/fonts/TTF/VeraBd.ttf
-@end example
-
-Usage Example:
-@example
- # Remember to set the path to your fonts
- FONTPATH="/cygdrive/c/WINDOWS/Fonts/"
- FONTPATH="$FONTPATH:/usr/share/imlib2/data/fonts/"
- FONTPATH="$FONTPATH:/usr/X11R6/lib/X11/fonts/TTF/"
- export FONTPATH
-
- # Time and date display
- ffmpeg -f video4linux2 -i /dev/video0 \
- -vhook 'vhook/drawtext.so -f VeraBd.ttf -t %A-%D-%T' movie.mpg
-
- This example grabs video from the first capture card and outputs it to an
- MPEG video, and places "Weekday-dd/mm/yy-hh:mm:ss" at the top left of the
- frame, updated every second, using the Vera Bold TrueType Font, which
- should exist in: /usr/X11R6/lib/X11/fonts/TTF/
-@end example
-
-Check the man page for strftime() for all the various ways you can format
-the date and time.
-
-@section watermark.c
-
-Command Line options:
-@multitable @columnfractions .2 .8
-@item @option{-m [0|1]} @tab Mode (default: 0, see below)
-@item @option{-t 000000 - FFFFFF} @tab Threshold, six digit hex number
-@item @option{-f <filename>} @tab Watermark image filename, must be specified!
-@end multitable
-
-MODE 0:
- The watermark picture works like this (assuming color intensities 0..0xFF):
- Per color do this:
- If mask color is 0x80, no change to the original frame.
- If mask color is < 0x80 the absolute difference is subtracted from the
- frame. If result < 0, result = 0.
- If mask color is > 0x80 the absolute difference is added to the
- frame. If result > 0xFF, result = 0xFF.
-
- You can override the 0x80 level with the -t flag. E.g. if threshold is
- 000000 the color value of watermark is added to the destination.
-
- This way a mask that is visible both in light and dark pictures can be made
- (e.g. by using a picture generated by the Gimp and the bump map tool).
-
- An example watermark file is at:
- @url{http://engene.se/ffmpeg_watermark.gif}
-
-MODE 1:
- Per color do this:
- If mask color > threshold color then the watermark pixel is used.
-
-Example usage:
-@example
- ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif' -an out.mov
- ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif -m 1 -t 222222' -an out.mov

- * Copyright (c) 2002 Philip Gladstone
- *
- * This file implements a fish detector. It is used to see when a
- * goldfish passes in front of the camera. It does this by counting
- * the number of input pixels that fall within a particular HSV
- * range.
- *
- * It takes a multitude of arguments:
- *
- * -h <num>-<num> the range of H values that are fish
- * -s <num>-<num> the range of S values that are fish
- * -v <num>-<num> the range of V values that are fish
- * -z zap all non-fish values to black
- * -l <num> limit the number of saved files to <num>
- * -i <num> only check frames every <num> seconds
- * -t <num> the threshold for the amount of fish pixels (range 0-1)
- * -d turn debugging on
- * -D <directory> where to put the fish images

- *
- * This module is very much intended as an example of what could be done.
- *
- * One caution is that this is an expensive process -- in particular the
- * conversion of the image into RGB and back is time consuming. For some
- * special cases -- e.g. painting black text -- it would be faster to paint
- * the text into a bitmap and then combine it directly into the YUV
- * image. However, this code is fast enough to handle 10 fps of 320x240 on a
- * 900MHz Duron in maybe 15% of the CPU.
-
- * See further statistics on Pentium4, 3GHz, FFMpeg is SVN-r6798
- * Input movie is 20.2 seconds of PAL DV on AVI
- * Output movie is DVD compliant VOB.

- * Watermark Hook
- * Copyright (c) 2005 Marcus Engene myfirstname(at)mylastname.se
- *
- * parameters for watermark:
- * -m nbr = nbr is 0..1. 0 is the default mode, see below.
- * -t nbr = nbr is six digit hex. Threshold.
- * -f file = file is the watermark image filename. You must specify this!
- *
- * MODE 0:
- * The watermark picture works like this (assuming color intensities 0..0xff):
- * Per color do this:
- * If mask color is 0x80, no change to the original frame.
- * If mask color is < 0x80 the abs difference is subtracted from the frame. If
- * result < 0, result = 0
- * If mask color is > 0x80 the abs difference is added to the frame. If result
- * > 0xff, result = 0xff
- *
- * You can override the 0x80 level with the -t flag. E.g. if threshold is
- * 000000 the color value of watermark is added to the destination.
- *
- * This way a mask that is visible both in light pictures and in dark can be
- * made (fex by using a picture generated by Gimp and the bump map tool).
- *
- * An example watermark file is at
- * http://engene.se/ffmpeg_watermark.gif
- *
- * MODE 1:
- * Per color do this:
- * If mask color > threshold color then the watermark pixel is used.
- *
- * Example usage:
- * ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif' -an out.mov
- * ffmpeg -i infile -vhook '/path/watermark.so -f wm.gif -m 1 -t 222222' -an out.mov
- *
- * Note that the entire vhook argument is encapsulated in ''. This
- * way, arguments to the vhook won't be mixed up with those for ffmpeg.
