Description

Note: This is my first bug report filed here, I believe it is correct according
to your guidelines, pls advise if it is not.

I have a large raw file from TV snap card (raw audio + video). After splitting
into multiple chunks (mencoder crashed on big file), mencoder crashes on only
certain input files.
This command fails:
mencoder /mnt/mroot/hdd2/ea-0014.avi -of mpeg -vf harddup -oac lavc -ovc lavc
-lavcopts
acodec=ac3:abitrate=192:vcodec=mpeg2video:keyint=25:vqmin=1:vqmax=9:vbitrate=7000:aspect=4/3
-srate 48000 -ofps 30000/1001 -o gbr.mpg

Re-encoding with just -ovc lavc works.
mencoder -ovc lavc -oac pcm -o rc.avi /mnt/mroot/hdd2/ea-0014.avi

Then, I noticed the original command segfaults at the same spot where the
shortened command starts to complain about A duplicate frame.

Then, upon realizing this, I removed the -vf harddup (unsure why Im using it
anyways), and it works fine.

Following the directions on this site, here is the gdb info I believe is
requested for a bug report.

(gdb) run /mnt/mroot/hdd2/ea-0014.avi -of mpeg -vf harddup -oac lavc -ovc lavc
