I have met the same bug(with latest cvs source code) described by
following poster in this maillist one year ago, and want to make sure
whether anyone has any idea about it?

I've compiled mplayer on a pent4 box and a amd athlon xp box and they
both exhiobit this same behavior. anyone have a clue as to what
When I use "mencoder -mc 0 -noskip dvd://1 -of mpeg -oac copy -ovc
copy -tt xxx -endpos xxx ...", several seconds(e.g.300 seconds) later
mencoder tell me "too many audio packages in buffer..." and exit. When
mencoder is encoding, it eats memory more and more and doesn't release
it properly. I mean when I change (demuxer.h) #define MAX_PACKS 4096
to 409600 and #define MAX_PACK_BYTES 0x800000 to 0x80000000 , it will
never pop up "too many audio packages in buffer..." message but it
has eaten up more than 1GB memory for encoding 50 minutes DVD!!! Then
I'm sure there is memory leak for mencoder -mc 0 -noskip to dealing
with 5.1 audio stream.
(Maybe you will suggest me to use mplayer -dumpstream, but I want
to use mencoder -ss and -endpos feature.)
Looking forward to your reply and thanks!
