Description
Hi there,
I beleive this is a common problem when using ffmpeg in a C++ program. This link provides the detail of what needs to be patched to fix the problem.
To be clear, this is the error output I get from my program when I include "libavutil/common.h"
/opt/local/include/libavutil/common.h: In function 'int32_t av_clipl_int32_c(int64_t)': /opt/local/include/libavutil/common.h:170:47: error: 'UINT64_C' was not declared in this scope
Hope this can be solved simply. Sorry that I can't submit the patch myself, I'm not to confident with Portfiles...

After further searching, maybe this isn't the way to fix this. Apologies. I still can't get my program to work, however...

Is this still a problem with the current version?

The error likely no longer occurs as reported; a check that has since been added would show a different error message. See https://github.com/FFmpeg/FFmpeg/commit/66872161cb

The upstream change I linked to is effectively the result of upstream's rejection of the patch the reporter attached here; they believe user C++ code is responsible for defining __STDC_CONSTANT_MACROS. See wiki page "Including FFmpeg headers in a C++ application" and lengthy mailing list discussion regarding the patch.
Possible patch of libavutil/common.h
