Thank you for your kind help, I configured and compiled ffmpeg successfully,
but there is a new problem now while I configure VLC with the new ffmpeg with faad support enabled,
the configuration shows that the compiler can't find the -lfaad,
It seems that the configuration script doesn't add the path of the FAAD path to the LDFLAGS,
but after I added it and compiled, the program runs with error information prompted:
libfaad.so.0 can't load: no such file or directory.
why this happened? Should I compile ffmpeg with static link with faad? how can I do?
Currently I think the faad library wasn't staticly linked to FFMPEG.
I just add the LDFLAGS in the config.mak with the FAAD library path,
if we should staticly link the faad, how to do?
Thank you and best regards,

Welcome to the ffmpeg hell ;-)
ffmpeg has a broken build system if there is more then one library that
needs to be statically linked and those libraries are in their own
compiled tree. The easiest thing todo is to create a directory under
ffmpeg, eg: libs and copy all *.a or *.so to that directory.
Configure ffmpeg with the option to the libraries configuration and with
