[MPlayer-DOCS] [PATCH] update x264 parameters in man page

Hello,

x264 has grown out of sync with the documentation in the mplayer man
page. This patch attempts to correct that by changing every incorrect
default I found and by documenting every undocumented parameter which I
was able to describe.

Most of the descriptions are from the x264 commit messages and the
source code. I make no guarantee that the parameters are described
correctly--I did my best, but I haven't (yet) used many of them.

* update defaults:
  frameref to 3
  bframes to 3
  subq to 6
  trellis to 1
  threads to 0 (auto)

* document the following parameters:
  intra_refresh
  mbtree
  rc_lookahead
  weightp
  psy
  sliced_threads
  slice_max_size
  slice_max_mbs
  slices
  sync_lookahead
  deterministic
  constrained_intra
  aud
  dump_yuv

There are several parameters for which I am unable to write a coherent
description; these are not included in the patch:

overscan
videoformat
fullrange
colorprim
transfer
colormatrix
chromaloc
cabac_idc
sps_id
annexb


Comments?

Thanks,
Corey
