[MEncoder-users] mencoder with mpeg12 decoder crash

[John Ratliff]

I have been trying to transcode MPEG2/AAC videos into MKV/H264/VORBIS 
vidoes using mencoder.

I am using MEncoder SVN-r32415-snapshot-4.4.3 (snapshot from a week or 
two ago) on Linux x64 (Kubuntu 10.04 if it matters).
I got vorbis-tools from apt-get and built the most recent snapshot (at 
the time) of x264.

When I run this command line:

nice /usr/local/bin/mencoder input.mpg -o output.avi -nosub -vc mpeg12
-vf softskip,scale=640:352:0,harddup
-sws 10 -af volume=10:0 -oac pcm -ovc x264
-x264encopts crf=25:nointerlaced:force_cfr:frameref=3:mixed_refs:
bframes=10:b_adapt=1:b_pyramid=normal:weight_b:
weightp=1:direct_pred=spatial:aq_mode=2:me=hex:subq=5:
nombtree:chroma_me:trellis=1:cabac:deblock:no8x8dct:
partitions=p8x8,b8x8,i4x4:nofast_pskip:nodct_decimate:
threads=auto:ssim:psnr

I get a seg fault.

But remove the -vc mpeg12 line and I get none.

I don't get this on every video, just some. Most 720p TV programs I get 
from my TiVo have this problem.

Thanks for any suggestions,
