[MPlayer-users] Problem with constant quantizer encoding

[Stefan Baehre]

For doing constant quantizer encoding with different quantizers for
I/P and B frames, manpage says:

"Tip: To do constant quantizer encoding with different quantizers
for I/P and B  frames  you  can  use:  vqmin=<ip_quant>:vqmax=
<ip_quant>:vb_qfactor= <b_quant/ip_quant>"

This doesn't work with current CVS. I tried:

-lavcopts vcodec=mpeg4:psnr:vmax_b_frames=2:vb_strategy=0:vqmin=2:vqmax=2:vb_qfactor=1.5:vb_qoffset=0

But I get Q=2 for all frame types, not 2 for I/P and 3 for B as I
expected.
