I am using mencoder 1.0pre3-2.95.3 on OpenBSD. I wanted to convert an MPEG file into an AVI file because it was always crashing mplayer. I used the command: mencoder -oac mp3lame -ovc lavc -lavcopts vcodec=mpeg4 file.mpg And I got the error Segmentation fault (core dumped) Trem: 12 min 242mb A-V:-0.040 [802:143] Any suggestions?
