This git module contains template code for possible GStreamer plugin projects with C++.
gst-plugin basic autotools layout and basic filter code for writing a GStreamer plug-in.
This code is provided under a MIT license [1], which basically means "do with it as you wish, but don't blame us if it doesn't work". You can use this code for any project as you wish, under any license as you wish. We recommend the use of the LGPL [2] license for applications and plugins, given the minefield of patents the multimedia is nowadays. See our website for details [3].
Build "myfilter" like this:
cd gst-plugin
./autogen.sh
Modify gst-plugin/src/Makefile.am to add or remove source files to build or add additional dependencies or compiler flags or change the name of the plugin file to be installed. Run ./autoregen.sh if changes don't take effect automatically on 'make'.
Modify gst-plugin/configure.ac to check for additional library dependencies or other features needed by your plugin. Run ./autoregen.sh if changes don't take effect automatically on 'make'.
Once the plugin is built you can either install it with 'sudo make install' (however, this will by default go into the /usr/local prefix where it won't be picked up by a GStreamer installed from packages, so you would need to set the GST_PLUGIN_PATH environment variable to include or point to /usr/local/lib/gstreamer-1.0/ for your plugin to be found by a from-package GStreamer). Alternatively, you will find your plugin binary in gst-plugins/src/.libs/ as libgstplugin.so or similar (the extension may vary), so you can also set the GST_PLUGIN_PATH environmen variable to the gst-plugins/src/.libs/ directory (best to specify an absolute path though). To enable plugins, add it to your bashrc or run the line below in your terminal:
export GST_PLUGIN_PATH='/usr/local/lib/gstreamer-1.0'
You can also check if it has been built correctly with:
gst-inspect-1.0 /usr/local/lib/gstreamer-1.0/libgstmyfilter.so
