add_dependency
Description:
public void add_dependency (
string[]? env_vars,
string[]? paths,
string[]? names,
PluginDependencyFlags flags)
Make GStreamer aware of external dependencies which affect the feature set of this plugin (ie.
the elements or typefinders associated with it).
GStreamer will re-inspect plugins with external dependencies whenever any of the external dependencies change. This is useful for plugins
which wrap other plugin systems, e.g. a plugin which wraps a plugin-based visualisation library and makes visualisations available as
GStreamer elements, or a codec loader which exposes elements and/or caps dependent on what external codec libraries are currently
installed.
Parameters:

| env_vars |
null-terminated array of environment variables affecting the feature set of the plugin (e.g. an environment variable

followed by a path component which will be added to the content of the environment variable, e.g. "HOME/.mystuff/plugins".
|
| paths |
null-terminated array of directories/paths where dependent files may be, or null.

null-terminated array of file names (or file name suffixes, depending on flags) to be used in combination
