[FFmpeg-devel] [V2] Updated version

[Andreas Rheinhardt]

I have incorporated James' suggestions regarding the comments. This of
course necessitated a rebase and because there were merge conflicts to
be solved in h264_redundant_pps I'm resending all patches after #9. I
also add the patches from my earlier patchsets [1] (dealing mostly with
mpeg2) and [2] (about updating the AVCodecParameters).
