gst-libs/gst/play/play.c (gst_play_audio_fixate)

Original commit message from CVS:
* gst-libs/gst/play/play.c (gst_play_audio_fixate)
(gst_play_video_fixate): Check so the structure has the field
before trying to fixate them, this makes it possible to have
fakesinks for video and audio output without printing errors on
the output console.
