Hi,

I'm using mencoder Pre9 (actually from CVS but a bit after pre9 got released).
I had this problem since Pre8 if I recall correctly but have not used mencoder
before pre8, so it could be a generic problem.  I just encoded 2 or 3 movies and
everytime, they complete, but at the end it output that error message:  
The result is that the index is not written out but the movie is completed. 
I have to run mencoder -idx -ovc copy -oac copy -o output.avi input.avi for
the file to be repaired.

mencoder: ratecontrol.c:579: ff_rate_estimate_qscale: Assertion 
`picture_number<rcc->num_entries' failed.

I'm running 2-pass mode and it fails at the end of the 2nd pass.

My command line was:
cat *vob | mencoder -oac mp3lame -lameopts abr:br=128:vol=3:aq=0 -aid 128 -ovc lavc 
-lavcopts vcodec=mpeg4:vbitrate=668:vhq:vqmin=1:vqmax=31:vpass=2 -ofps 23.976  
-vop scale=544:288,crop=720:456:0:10 -o output.avi -

Maybe it's the vqmin/vqmax that causes this?
