Original commit message from CVS: gst_play_get_sink_element has been improved : - Recursively searches in bins - Able to find sink_element of a specified GstPlaySinkType (audio,video,any) This now allow us to send very complex bins to GstPlay for audio/video sink without breaking length querying, eos signaling, etc..
