I ran callgrind on a HD mpeg2 video file and I get the following (averaged
instructions/calls)

instruction/calls    | git       | +1st patch  | +2nd patch
------------------------------------------------------------------
gst_mpeg_video_parse | 1 446 974 | 420 373     | 310 743

                                   (29.1%)     | (21.5%)

So essentially it's 5 times faster.
