=head1 NAME
GStreamer1 - Bindings for GStreamer 1.0, the open source multimedia framework
=head1 SYNOPSIS
use GStreamer1;
GStreamer1::init([ $0, @ARGV ]);
my $pipeline = GStreamer1::parse_launch( "playbin uri=$URI" );
$pipeline->set_state( "playing" );
my $bus = $pipeline->get_bus;
my $msg = $bus->timed_pop_filtered( GStreamer1::CLOCK_TIME_NONE,
[ 'error', 'eos' ]);
$pipeline->set_state( "null" );
=head1 DESCRIPTION
GStreamer1 implements a framework that allows for processing and encoding of
multimedia sources in a manner similar to a shell pipeline.
Because it's introspection-based, most of the classes follow directly from the
C API. Therefore, most of the documentation is by example rather than
a full breakdown of the class structure.
=head1 PORTING FROM GStreamer
If you're porting from the original GStreamer module, here are some things
to keep in mind.
=head2 ElementFactory
The original GStreamer had a version of C<< ElementFactory->make() >> which
could be called with a list of gst plugins and associated names. GStreamer1
may add a similar method in the future. For now, the bindings directly follow
from the C interface, so they take only one at a time.
Example:
my $rpi = GStreamer1::ElementFactory::make( rpicamsrc => 'and_who' );
my $h264parse = GStreamer1::ElementFactory::make( h264parse => 'are_you' );
my $capsfilter = GStreamer1::ElementFactory::make(
capsfilter => 'the_proud_lord_said' );
my $avdec_h264 = GStreamer1::ElementFactory::make(
avdec_h264 => 'that_i_should_bow_so_low' );
my $jpegenc = GStreamer1::ElementFactory::make( jpegenc => 'only_a_cat' );
my $fakesink = GStreamer1::ElementFactory::make(
fakesink => 'of_a_different_coat' );
=head2 Adding/linking
The original GStreamer added methods for C<< Pipeline->add() >> and
C<< Element->link() >> that could take lists of objects. GStreamer1 may add
similar methods in the future. For now, the bindings directly follow from the
C interface, so they take only one object at a time.
Example:
my @link = ( $rpi, $h264parse, $capsfilter, $avdec_h264, $jpegenc, $fakesink );
$pipeline->add( $_ ) for @link;
foreach my $i (0 .. $#link) {
last if ! exists $link[$i+1];
my $this = $link[$i];
my $next = $link[$i+1];
$this->link( $next );
}
=head1 EXAMPLES
See the C directory in the distribution.
=head1 SEE ALSO

=head1 SPECIAL THANKS
To Torsten Schönfeld for pointing me in the right direction on creating
this module.
