[MPlayer-DOCS] [PATCH] lavc opts update

[Loren Merritt]

vb_strategy does not cause bitrate misprediction, but works only on the 
first pass.
keyint=0 means all I-frames, not no I-frames.
mbqmin / mbqmax no longer do anything.

+0 is equivalent to 1, which makes every frame a keyframe.
 Values >300 are not recommended as the quality might be bad depending upon
 decoder, encoder and luck.
 For a strict MPEG1/\:2/\:4 compliance this would have to be <=132.

 Always use the maximum number of B-frames (default).

 Avoid B-frames in high motion scenes.
