NAME

         GStreamer1 - Bindings for GStreamer 1.0, the open source multimedia framework

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" );

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.

PORTING FROM GStreamer

       If you're porting from the original GStreamer module, here are some things to keep in mind.

   ElementFactory
       The original GStreamer had a version of "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' );

   Adding/linking
       The original GStreamer added methods for "Pipeline->add()" and "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 );
           }
