I'm not compiling pure C code. I'm compiling C++ code and I want
to call the libav surboutines from C++ code. How do I do this?
One of your questions was:
"How difficult would it be to compile the examples in the doc/examples
directory with a C++ compiler?"
Those are C programs, so just use a C compiler for them. That's all I
meant.
Yes, you can call C functions from a C++ program. I think many C header
files have a guard like:
#ifdef __cplusplus
extern "C" {
#endif
...
#ifdef __cplusplus
}
#endif
to make sure C++ compilers don't mangle the symbols, but the headers I
use don't have that. So I just added it myself, around my C includes:
extern "C" {
#include "libavformat/avformat.h"
etc...
}
and then you can call them normally from your C++ apps.
