[MEncoder-users] Some problem with mencoder lumi_mask and dark_mask option.

[yong]

Here is the mencoder options i always use:
start /b /belownormal /w mencoder %* -noskip -mc 0 -vf crop=640:368,denoise3d
-audio-preload 2.0 -oac copy -ovc lavc -lavcopts
vcodec=mpeg4:autoaspect:keyint=300
:vmax_b_frames=2:vbitrate=600:lumi_mask=0.3:dark_mask=0.3:tcplx_mask=0.1
:scplx_mask=0.1:p_mask=0.1:vb_qfactor=1.50
:vb_qoffset=1.00:predia=2:dia=2:preme=2
:v4mv:trell:mv0:mbd=2:qprd:cbp:naq -o "%userprofile%\desktop\%~n1.avi"

The encoded video looks fine untill i removed the
v4mv,trell,mbd=2,qprd and cbp options,
i got some message from mplayer when decoding the video files:
[mpeg4 @ 00AD3158]ac-tex damaged at 13 7 353/353  0%  1%  0.1% 0 0 61%

...

Not only mplayer, ive also noticed same problem(visible artifact)
when decode with xvid decoder.
