Provide printing macros for ffmpeg header #47

Closed tongyuantongyu closed 1 year ago

tongyuantongyu commented 1 year ago

On glibc < 2.18, PRId64 and likewise is only provided under cpp if __STDC_FORMAT_MACROS is defined.

Also, don't override CMAKE_CXX_FLAGS,as these can be specified through command line, if compiling for target environment need some extra compiler flags.

代码中有用到这个MACROS的地方？ 是给后续预留么

是引入的ffmpeg头用到的：https://github.com/FFmpeg/FFmpeg/blob/n4.4.4/libavutil/timestamp.h#L29

<cinttypes>有时会define __STDC_FORMAT_MACROS，一开始排查问题按照编译器提示添加了<cinttypes>的引入，现在测试了一下，手动定义__STDC_FORMAT_MACROS之后不需要#include <cinttypes>了。
