[x264-devel] Entry into Scaling List

--cqm4iy, --cqm4ic, --cqm4py, --cqm4pc: Set individual quant matrices. Same
switches exist for cqm8
Suggests that there should be a --cqm8iy.

It works here http://privatepaste.com/25a4861dde . I used command line:
x264 foreman_cif_352x288.yuv -o test.h264 --cqm8i
16,19,20,23,24,26,32,42,18,19,22,24,26,32,36,42,18,20,23,24,26,32,36,63,19,20,23,26,32,36,42,63,20,22,24,26,32,36,59,63,22,23,24,26,32,36,59,68,22,23,24,26,32,42,59,68,22,23,24,26,36,42,59,72
 Post your full command line.

--nal-hrd cbr --pic-struct --aud --fps 25 -v --muxer raw -o $2 $1
