To get a backtrace, you need to use debugging tools, such as valgrind or
gdb; ffmpeg_g is just a version of ffmpeg where the debugs symbols are still
present, making the file larger but the backtrace much more accurate.

To see how to produce the backtraces, check out:

Got it, but I can not reproduce the segfault, even with valgrind. Are you
sure it happens with the file you uploaded too?

If so, please describe your build environment exactly.
