- compile the C library as normal using gcc
- include the C (*.h) headers like this:
extern "C" {
#include <libavcodec/avcodec.h>
}
- compile the C++ files as normal using g++
Don't compile C files using C++ compilers (e.g. g++), it will change
their symbol names. Don't forget the extern "C", that is meant to
prevent symbol name-changes in the lavc functions being linked to from
within the C++ app. If you do all of these correctly, it should work
just fine.
If it doesn't work, please provide some compiler commands that you're
using to compile ffmpeg, your c++ app and the c++ app code.
