NAME
       GStreamer - Perl	interface to the GStreamer library

SYNOPSIS
	 use GStreamer -init;

	 my $loop = Glib::MainLoop -> new();

	 # set up
	 my $play = GStreamer::ElementFactory -> make("playbin", "play");
	 $play -> set(uri => Glib::filename_to_uri $file, "localhost");
	 $play -> get_bus() -> add_watch(\&my_bus_callback, $loop);
	 $play -> set_state("playing");

	 # run
	 $loop -> run();

	 # clean up
	 $play -> set_state("null");

	 sub my_bus_callback {
	   my ($bus, $message, $loop) =	@_;

	   if ($message	-> type	& "error") {
	     warn $message -> error;
	     $loop -> quit();
	   }

	   elsif ($message -> type & "eos") {
	     $loop -> quit();
	   }

	   # remove message from the queue
	   return TRUE;
	 }

ABSTRACT
       GStreamer makes everybody dance like crazy.  It provides	the means to
       play, stream, and convert nearly	any type of media -- be	it audio or
       video.  GStreamer wraps the GStreamer library in	a nice and Perlish
       way, freeing the	programmer from	any memory management and object
       casting hassles.

INITIALIZATION
       GStreamer->init
	   Initializes GStreamer.  Automatically parses	@ARGV, stripping any
	   options known to GStreamer.

       boolean = GStreamer->init_check
	   Checks if initialization is possible.  Returns TRUE if so.

       When importing GStreamer, you can pass the "-init" option to have
       GStreamer-_init automatically called for	you.  If you need to know if
       initialization is possible without actually doing it, use
       GStreamer-_init_check.

VERSION	CHECKING
       boolean = GStreamer->CHECK_VERSION (major, minor, micro)
	   o   major (integer)

	   o   minor (integer)

	   o   micro (integer)

	   Returns TRUE	if the GStreamer library version GStreamer was
	   compiled against is newer than the one specified by the three
	   arguments.

       (major, minor, micro) = GStreamer->GET_VERSION_INFO
	   Returns the version information of the GStreamer library GStreamer
	   was compiled	against.

       (major, minor, micro) = GStreamer->version
	   Returns the version information of the GStreamer library GStreamer
	   is currently	running	against.

SEE ALSO
       GStreamer::index
	   Lists the automatically generated API documentation pages.

       <http://gstreamer.freedesktop.org/>
	   GStreamer's website has much	useful information, including a	good
	   tutorial and	of course the API reference, which is canonical	for
	   GStreamer as	well.

       Gtk2::api
	   Just	like Gtk2, GStreamer tries to stick closely to the C API,
	   deviating from it only when it makes	things easier and/or more
	   Perlish.  Gtk2::api gives general rules for how to map from the C
	   API to Perl,	most of	which also apply to GStreamer.

       Glib
	   Glib	is the foundation this binding is built	upon.  If you look for
	   information on basic	stuff like signals or object properties, this
	   is what you should read.
