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?
That is confusing. The libraries that make up ffmpeg include
libavcodec, libavformat etc. Hence the list - it's for users of the
libraries, not the ffmpeg binary. To confuse matters, there was a
fork, and they called that project LibAV.
So - you're using libavformat, libavcodec etc. But - are you using
source code obtained from the ffmpeg project, or the libav project?
This list is specific to the ffmpeg project.
Anyway, don't bother. I give up. You win.
LOL. I feel your pain. Sadly, a certain amount of chaff comes with
using FOSS systems (nothing personal to the chaff providers on this
thread). Lots of personalities. The upside outweighs the cost in
humility that is required.
Anyway... LibAV, I have no idea. FFmpeg, yes, you can compile and use
it from C++ with very little problems - just the packaging around the
headers so the compiler knows they are C, not C++.
When I compile demuxing.c with g++ it gives me the same errors as
when I add libav calls to my C++ app and then try to compile that
with g++. So, if we can figure out why demuxing.c won't compile with
g++, then we will probably figure out why my C++ app won't compile
with g++.
This: just wrong. The fact that one C based example does or does not
compile offers no evidence as to what your actual problem is.

Hello,
I did just fine with my c++ app and even with a c++ dll that exposed a
simplified set of av_codec compression functions.
As someone mentioned earlier, it was as easy as:
extern "C" {
#include <avcodec.h>
#include <avformat.h>
#include <swscale.h>
#include <imgutils.h>
}
Have Fun!
