 Replying to [comment:3 Carl Eugen Hoyos]:

 Debugging a native Android process via gdb or lldb is not impossible but
 very difficult. I tried a few times but I wasn't successful. I attached
 the tombstone file instead. Does it include the disassembly we need? I
 don't know how disassembly looks like to be honest.

 I'm not sure who to blame here, ffmpeg or x264. Yes, the crash happens
 inside x264 methods, but ffmpeg calls those methods. Maybe parameters
 passed by ffmpeg are wrong. And the crash is the result of that. For me,
 it's hard to say who should own this.

 If ffmpeg devs could have a look at the crash and check if everything is
 looking good from ffmpeg perspective that would be quite helpful I
 believe.
