[MPlayer-users] SIGSEGV with -vop pp

From the moment the -vop pp, -pp, -npp usage changed, I can't get
postprocessing to work. I always get a Segmentation Fault from mplayer
at the very start of the file. The moment the window for the movie is
created, that moment the sigsegv comes. The crash happens with every
video out device I tried (from xmga to x11) and with every -vop
pp=<> compination (Even if I give just the -vop pp in the command line
there is a crash). I also tried with --disable-mmx and got the same
sigsegv.
MPlayer interrupted by signal 11 in module: decode_video
