gst-opencv is a plugin for the GStreamer framework, consisting of both elements mapped directly to OpenCV functions as well as composite elements using a combination of functions.

• gstreamer and gst-plugins-base (>=0.10.29)
• OpenCV (>=2.0?)
• autoconf (>=2.52), automake (>=1.7), libtool (>=1.5.0), and pkg-config (>=0.11.0)
• OR CMake (>=2.8?)

There are two ways to build gst-opencv, the traditional make system and CMake.

Read INSTALL for more information, but in short:

./autogen.sh --prefix=/gstreamer/plugins/dir
make
make install

CMake can be used to generate build files for a number of different build systems, including make and Visual Studio. It is recommended to perform an out-of-place by creating a subdirectory for the build files. To see a list of the available build generators simply run cmake. The following are just two of the many combinations of platforms and build systems that can be used.

You'll need to specify the location of required libraries by setting some environment variables:

set GSTREAMER_DIR=C:\gstreamer
set LIBXML2_DIR=%GSTREAMER_DIR%
set LIBICONV_DIR=%GSTREAMER_DIR%
set GLIB2_DIR=%GSTREAMER_DIR%
set OPENCV_DIR=C:\opencv

To generate a Visual Studio 2008 solution file and install the resulting plugins in C:\gstreamer\plugins run the following commands:

mkdir build
cd build
cmake .. -G "Visual Studio 9 2008" -DCMAKE_INSTALL_PREFIX=C:\gstreamer\plugins

Alternatively, you can use the CMake gui, cmake-gui.

Once the build files have been generated, open the solution file and either "Build Solution" or build the ALL_BUILD project. To install the plugin, issue a build command on the INSTALL project.

To generate makefiles, build, then install, run the following commands:

mkdir build
cd build
cmake .. -G "Unix Makefiles" -DCMAKE_INSTALL_PREFIX=/gstreamer/plugin/dir
make
make install
