I use mencoder to convert a DVD to DIVX. This script has not been altered and I use the following mencoder command line mplayer dvd://1 -dvd-device ... -dumpstream -dumpfile vid.m2v mencoder vid.m2v -ovc lavc -lavcopts vcodec=mpeg4:vpass=1:v4mv:dia=4:trell:vmax_b_frames=2:vb_strategy=1:autoaspect -nosound -ffourcc DX50 -o /dev/null mencoder vid.m2v -ovc lavc -lavcopts vcodec=mpeg4:vpass=2:v4mv:dia=4:trell:vmax_b_frames=2:vb_strategy=1:autoaspect -nosound -ffourcc DX50 -o video0.avi I havent used this for a while - so now I keep getting: [mpeg2video @ 0xb6041400]get_buffer() failed (stride changed) Error while decoding frame! My slackware test system (mplayer 1.1) doesnt have the issue but I cannot compile mplayer-1.1 due to some gentoo-bug. Any ideas? Reproducible: Always Steps to Reproduce: 1.try to convert mpeg2 2. 3. Actual Results: [mpeg2video @ 0xb6041400]get_buffer() failed (stride changed) Error while decoding frame! Expected Results: converting the video
