Gnolin/Python - decoding 2 video streams

[Matt Veenstra]

Solved.  My bug.  Copy and paste error on the caps.

		self.stream1.set_property("caps", gst.caps_from_string("video/x-raw-yuv"))
 		self.stream2.set_property("caps", gst.caps_from_string("audio/x-raw-yuv"))

I am sure there will be more questions.
