This function is needed for development in MS Visual Studio, win32/64, because
the exported array av_pix_fmt_descriptors[] is recognized as a function, not as
data.
Do you know why it does that?
Sorry, my fault.
I've studied the produced DLL with the Dependency Walker, which seems to show
everything as a function, either C or C++. It has icons, defining only
functions.
Anyway, there is another problem - in name decorations.
I use this array in the C++ code, the header is included as
extern "C" {
#include<libavutil/pixdesc.h>
}
And the compiler expects the underscore in the beginning of the name.
But Mingw didn't produce underscore for av_pix_fmt_descriptors.
I have compiled libav using MingW-W64 on Linux, but use it in windows.
I had to produce import libraries for visual studio by myself using the lib.exe
utility,
because 'make' had made several failed calls to the lib.exe, which is obviously
missing in linux:
Strange, our build system does not use lib.exe to generated imports but
mingw ld/dlltool
If you really want to use lib.exe you can just copy it and have the
binfmt supporting it through wine. You might have better result using
our tree btw.
