Subject: [PATCH 3/3] h264parse: default to byte-stream/nalu format (Annex B).

Always default to stream-format=byte-stream,alignment=nalu if avcC
format was not detected. This is the natural stream format specified
in the standard (Annex.B): a series of NAL units prefixed with the
usual start code.
