The av_err2str macro in libavutil/error.h use compound literal:

#define av_err2str(errnum) \

C++ compiler may not support it or treat the usage as invalid.
For example, g++ 5.4 raise an error: taking address of temporary

1. Should the macro be defined for C only?
2. Or make it as valid C++? (I don't know how to do that)
