What I did was this.
First: find the files where are those functions or methods that are
undefined.
For this error, for example:
./modules/codec/ffmpeg/libffmpeg.a(libffmpeg_a-postprocess.o): In
function `InitPostproc__ffmpeg':
/home/vlc/vlc-0.8.4a/modules/codec/ffmpeg/postprocess.c:164: undefined
reference to `_pp_get_context'
Find where is the implementation of _pp_get_context in the source of
vlc.
Second:
Find how vlc builds libffmpeg.a, I suggest you to delete it, and in that
directory run make. You will see in the screen the command
arm-linux-ar cru libffmpeg.a <sources for the library>
arm-linux-ranlib libffmpeg.a
Third:
Run your own script adding the files you need to the arm-linux-ar:
arm-linux-ar cru libffmpeg.a <sources for the library> <the ones you
want to add>
arm-linux-ar cru libffmpeg.a
On this way you have solved the undefined referenced to these functions.
I'll send again my script in English ;-).
Good Luck, and if you have problems do not hesitate to ask me I hope it
works.
