remove x264 option "cabacidc", because the default is always best.

@ -7757,23 +7757,6 @@ Slightly slows down encoding and decoding, but should save 10-15% bitrate.
Unless you are looking for decoding speed, you should not disable it.
.
.TP
.B cabacidc=<value>
Initial value of CABAC IDC.
The encoder must choose a context for each block it encodes, but for the
first block in a frame, there are no prior blocks to predict the context.
Adjusting this may affect bitrate by a fraction of a percent, but it doesn't
directly affect distortion.
.RSs
-1: Encoder chooses context, usually 0 (default).

0: low complexity

1: medium complexity

2: high complexity

.TP
.B qp_min=<1\-51> (CBR or two pass)
Minimum quantizer, 10\-30 seems to be a useful range (default: 10).
