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.
