Hi All
I want to decode raw mpeg4 stream, but I have always got such errors:
Program received signal SIGFPE, Arithmetic exception.
[Switching to thread 1944.0x45c]
0x008bcf61 in __divdi3 () at ../../include/vlc_meta.h:112
112 }
Current language: auto; currently c++
(gdb) bt

Could anyone explain what causes such crashing? Thanks lot.
