Hello all:
I created a class FFMpegMgr and a method init(); inside init() I just put
three ffmpeg api there:
avcodec_register_all();
avdevice_register_all();
av_register_all();
The source file ffmpegmgr.cpp look like this:
void FFMpegMgr::init() {
avcodec_register_all();
avdevice_register_all();
av_register_all();
}
Now I got a "undefined reference to avcodec_register_all" error.
if I put that body in the class declaration or add a "inline" keyword, that
problem was gone and the compilation succeeded.
question is, do those three functions, which are C functions defined in
avcodec.h, have to be used only in the inline functions in C++?
Sorry if it appear naive - I've been out of touch with C/C++ for a while.
Thanks!
Hai
