vc1parser: re-enable BDU parsing for bitstream
@vjaquez
Submitted by Víctor Manuel Jáquez Leal Link to original bug (#743948)
Description
Currently the parser is not able to parse bitstream like in this pipeline:
gst-launch-1.0 filesrc location=mytestfile.vc1 ! vc1parse ! ..
Since the parser bails out with an error message.
This patch proposes a way re-enable it.
