put attach files into ffmpeg source dir or tests dir, run tst_gxx.sh
g++ -I.. -I. -D__STDC_CONSTANT_MACROS -c -o tst_gxx.o tst_gxx.cpp
tst_gxx.cpp: In function 'int main()':
tst_gxx.cpp:5:5: error: taking address of temporary array
make: *** [tst_gxx.o] Error 1
i think we can use a inline function instead of macro
av_always_inline char* av_err2str(int errnum)
{
static char str[AV_ERROR_MAX_STRING_SIZE];
memset(str, 0, sizeof(str));
return av_make_error_string(str, AV_ERROR_MAX_STRING_SIZE, errnum);
}
