Hi All,

I have a piece of code that runs GStreamer in linux written in the following code that I'd like to integrate with a large wxPerl system. Ideally I'd do it using wxMediaCtrl directly but that has totally failed to work (See wxMediaCtrl running under Kubuntu 9.10). So failing that I can find a GStreamer Perl interface and embed that in my application. Unfortunately for me, it uses Glib, which is a new area for me.

So I have this GStreamer code which works (change the avi file name):

#!/usr/bin/perl -w -- 
  use strict;
  use warnings;
  
  use GStreamer -init;

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

  # set up
  my $file = '/home/steve/media/test.avi';
  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 1;
  }

and I'd like to include it in a piece of wxPerl code like this: (but have it in the second frame so that I can add other widgets.)

#!/usr/bin/perl -w -- 

use Wx 0.15 qw[:allclasses];
use strict;
use warnings;
  
use GStreamer -init;

package MyFrame;

use Wx qw[:everything];
use base qw(Wx::Frame);
use strict;

sub new {
    my( $self, $parent, $id, $title, $pos, $size, $style, $name ) = @_
+;
    $parent = undef              unless defined $parent;
    $id     = -1                 unless defined $id;
    $title  = "frame_1"                 unless defined $title;
    $pos    = wxDefaultPosition  unless defined $pos;
    $size   = wxDefaultSize      unless defined $size;
    $name   = ""                 unless defined $name;


    $style = wxDEFAULT_FRAME_STYLE 
        unless defined $style;

    $self = $self->SUPER::new( $parent, $id, $title, $pos, $size, $sty
+le, $name );
    my $file = '/home/steve/Documents/Endoscopia/media/a_1_2009_07_30_
+0.avi';
    $self->{media_1} = GStreamer::ElementFactory -> make("playbin", "p
+lay");
    $self->{media_1} -> set(uri => Glib::filename_to_uri $file, "local
+host");
    $self->{media_1} -> set_state("playing");

    $self->{sizer_1} = Wx::BoxSizer->new(wxVERTICAL);
    #$self->{sizer_1}->Add($self->{media_1}, 0, 0, 0);
    $self->SetSizer($self->{sizer_1});
    $self->{sizer_1}->Fit($self);
    $self->Layout();

    return $self;

}

package main;

unless(caller){
    local *Wx::App::OnInit = sub{1};
    my $app = Wx::App->new();
    Wx::InitAllImageHandlers();

    my $frame_1 = MyFrame->new();

    $app->SetTopWindow($frame_1);
    $frame_1->Show(1);
    $app->MainLoop();
}

Any ideas welcome.
