hmm, looks like that last step didn't do much because the error isn't in transcode. I am not sure how useful it will be, but it is easy so do this: apt-get install libc-dbg gdb... bt full, the #0 ... libc.so.6 should have something, which might be useful. If you built ffmpeg, see if you can enable debug info there too. -- Carl K
