Comment:

 (In [12750]) Closes #2984. mpeg start code optimizations

 use libavcodec's ff_find_start_code()
 it's three times faster than the current code in avformatdecoder and
 dtvrecorder (micro benchmarks)
 cleaned and optimized the H264 keyframe detection in H264Utils (more than
 30 times faster with oprofile)

 Idea and micro benchmarks by gnome42 [at] gmail.com
