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. - -Three modules are provided and are described below. They are all intended to -be used as a base for your own modules. - -Modules are loaded using the -vhook option to ffmpeg. The value of this parameter -is a space seperated list of arguments. The first is the module name, and the rest -are passed as arguments to the Configure function of the module. - -@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 allows a caption to be placed onto each frame. It supports inserting the -time and date. By using the imlib functions, it would be easy to add your own -graphical logo, add a frame/border, etc. - - -@bye |
