You override the GtkMediaPlayer::Play function with your own 
implementation. Something like this:

static void
hx_player_class_init(GtkHXPlayerClass* klass)
{
    GtkMediaPlayerClass* media_player_class = GTK_MEDIA_PLAYER_CLASS(klass);

    media_player_class->play = hx_player_play;
...
}

I believe GtkMediaPlayer would have a gtk_media_player_play that emits a 
play signal, and a gtk_media_player_real_play that provides a default 
implementation.

s/gstreamer/helix/g for me.

We do XEmbed with our mozilla plugin. Having a widget interface makes 
things a lot simpler. Consider the embedded developer working with gtk 
on the framebuffer, for instance. A complex embedding framework isn't 
going to work for him.

I can go into more details if you'd like. Helix would provide a library 
that contains an implementation of GtkMediaPlayer, and a set of 
supporting functions for advanced functionality.

This is a sincere effort to make media widgets easier to use with gtk, 
and it would benefit both gstreamer and helix.
