This is a mailing list about FFmpeg (that is why
it is hosted on the FFmpeg server). Questions
about how to convert a C program (that allows
implicit type conversions which is why FFmpeg
- and demuxing.c - does not contain explicit
type conversions) into a C++ program (which
needs explicit conversions) is not completely
appropriate here afaict.
Really? The title of the mailing list is [email protected].
I'm asking whether libav can be used in C++ programs, if anyone
uses libav in C++ programs, and what I need to do in order to
use libav in C++ programs. How can that be inappropriate?
Anyway, don't bother. I give up. You win.
You just need to wrap all you libav includes in extern "C" { }, like
this
#ifdef __cplusplus
extern "C" {
#include <libavutil/avutil.h>
#include <libavutil/mathematics.h>
#include <libavutil/imgutils.h>
#include <libavutil/samplefmt.h>
#include <libavutil/time.h>
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
#include <libswscale/swscale.h>
}
#endif // __cplusplus
As for UINT64_C you can do this
#ifndef INT64_C
#define INT64_C(c) (c ## LL)
#define UINT64_C(c) (c ## ULL)
#endif // INT64_C
I' m using libav in many of my projects which include other third
party libraries. The above are the only things required.
