[MPlayer-users] Segfault when encoding MPEG transport stream

[Adam Nielsen]

Hi,

I've found a point in one particular MPEG-TS file that repeatedly causes a 
segfault.  I compiled a debug version of mencoder and ran it in gdb, and this 
is what it came up with:

Program received signal SIGSEGV, Segmentation fault.

Does anyone know what's wrong?  The command line I used was:

mencoder -o /dev/null -mc 0 -noskip -skiplimit 0 -ovc lavc -lavcopts 
vcodec=mpeg4:vhq:trell:mbd=2:vmax_b_frames=1:v4mv:vb_strategy=0:vlelim=0:

Thanks,
Adam.
