libgstpbutils is a general utility library for plugins and applications, available since gst-plugins-base 0.10.12. It currently provides the following:
human-readable description strings of codecs, elements, sources, decoders, encoders, or sinks from decoder/encoder caps, element names, or protocol names.
support for applications to initiate installation of missing plugins (if this is supported by the distribution or operating system used)
API for GStreamer elements to create missing-plugin messages in order to communicate to the application that a certain type of plugin is missing (decoder, encoder, URI protocol source, URI protocol sink, named element)
API for applications to recognise and handle missing-plugin messages
You should obtain the required CFLAGS and LIBS using pkg-config on the gstreamer-plugins-base-0.10 module. You will then also need to add '-lgstpbutils-0.10' manually to your LIBS line.
Before using any of its functions, applications and plugins must call
gst_pb_utils_init()
to initialise the library.
void gst_pb_utils_init (void
);
Initialises the base utils support library. This function is not
thread-safe. Applications should call it after calling gst_init()
,
plugins should call it from their plugin_init function.
This function may be called multiple times. It will do nothing if the library has already been initialised.
Since 0.10.12
