Hi, I also have the same kind of crashes with the mjpegtools, but not only with mpeg2enc.
Precisely, the utility ppmtoy4m crashes in the same way. I noticed, because this utility is used frequently by the DVD authoring tools (QDVDAuthor, KmediaFactory). Here I cp all the info I have: $ uname -srm Linux 2.6.28-13-generic i686 $ grep name /proc/cpuinfo model name : AMD Athlon(tm) XP 2600+ $ ppmtoy4m image001.pnm -n 675 -r -S 420mpeg2 -F 25:1 -A 59:54 -I t -L >out.y4m INFO: [ppmtoy4m] Command-line Parameters: INFO: [ppmtoy4m] framerate: 25:1 INFO: [ppmtoy4m] pixel aspect ratio: 59:54 INFO: [ppmtoy4m] pixel packing: RGB INFO: [ppmtoy4m] interlace: top-field-first (interleaved PPM input) INFO: [ppmtoy4m] starting frame: 0 INFO: [ppmtoy4m] # of frames: 675, repeat last frame until done INFO: [ppmtoy4m] chroma subsampling: 4:2:0 MPEG-2 (horiz. cositing) INFO: [ppmtoy4m] Output Stream parameters: INFO: [ppmtoy4m] frame size: 800x600 pixels (720000 bytes) INFO: [ppmtoy4m] chroma: 4:2:0 MPEG-2 (horiz. cositing) INFO: [ppmtoy4m] frame rate: 25/1 fps (~25.000000) INFO: [ppmtoy4m] interlace: top-field-first INFO: [ppmtoy4m] sample aspect ratio: 59:54 Illegal instruction Debugging information $ gdb ppmtoy4m GNU gdb 6.8-debian Copyright (C) 2008 Free Software Foundation, Inc.
