whoops, I forgot we need to tell gdb to use libc-dbg echo set env LD_LIBRARY_PATH=/usr/lib/debug >> ~/.gdbinit for sure do that, run, gdb, bt, post. the rest of this is getting pretty fuzzy. Not why this is this: /usr/lib/i686/cmov/libavcodec.so.51 No symbol table info available. I am not sure how you installed ffmpeg, but you might want to uninstall yours and install a package from: http://ddebs.ubuntu.com/pool/multiverse/f/ffmpeg-extra/ which can be done by adding something like this to your sources.list: deb http://ddebs.ubuntu.com karmic main restricted more on that here: https://wiki.ubuntu.com/DebuggingProgramCrash > > [export_ffmpeg.so] Set display aspect ratio to input > [mpeg4 @ 0xa54ba610]removing common factors from framerate > > Program received signal SIGSEGV, Segmentation fault. > [Switching to Thread 0xb7c986b0 (LWP 30359)] > 0xb7d2e643 in strlen () from /lib/libc.so.6 > (gdb) bt full > #0 0xb7d2e643 in strlen () from /lib/libc.so.6 > No symbol table info available. > #1 0xa51637f2 in ff_parse () from /usr/lib/i686/cmov/libavcodec.so.51 > No symbol table info available. > #2 0xa5286a10 in ff_rate_control_init () from > /usr/lib/i686/cmov/libavcodec.so.51 > No symbol table info available. > #3 0x00000000 in ??
