[MPlayer-users] Video recode problem and memory leakage mencoder

[Boris Borisov]

Hello,

I try to convert mkv box to xvid format capable with Sony Bravia TV. And
all seems good until I receive some strange messages from MENCODER.
For converting I use:

/usr/bin/mencoder infile.mkv -noskip  -vf harddup -oac lavc -ovc lavc
-of mpeg -lavcopts
abitrate=256:vcodec=mpeg2video:keyint=1:vbitrate=8000:
vrc_maxrate=12000:vrc_buf_size=1835 -mpegopts muxrate=40000 -af
lavcresample=44100 -sub input.sub -font /etc/mediatomb/DejaVuSans.ttf
-subfont-autoscale 0 -subfont-text-scale 20 -subpos 100 -o output.avi

After some time I receive the messages:

The TV are run perfectly the video and audio until reach 82.5 sec frame
- then the picture freeze and audio continue.

What I do wrong?

Other problem is:
If I continue to recode the video, the memory and swap are fill and
process of mencoder recoding crash.

How I can limit the memory usage?
