New Revision: 27390
Log:
Fix a misleading section in the libavcodec options manual indicating that a
rc_eq of 1 will return a CBR encode and a rc_eq of tex a const QP encode;
likewise for qcomp.

Quantizer compression, vrc_eq depends upon this (default: 0.5).
-For instance, assuming the default rate control equation is used,
-if vqcomp=1.0, the ratecontrol allocates to each frame the number of bits
-needed to encode them all at the same QP.
-If vqcomp=0.0, the ratecontrol allocates the same number of bits to each
-frame, i.e. strict CBR.
.I NOTE:
-Those are extreme settings and should never be used.
-Perceptual quality will be optimal somewhere in between these two extremes.
