ffmpeg遇到inttypes.h和UINT64_C

编译过程：
错误一：无法打开包括文件:“inttypes.h”: No such file or directory
解决方法：删除之，并在其之前添加如下代码：

#if defined(WIN32) && !defined(__MINGW32__) && !defined(__CYGWIN__)
#      define CONFIG_WIN32
#endif
#if defined(WIN32) && !defined(__MINGW32__) && !defined(__CYGWIN__) && !defined(EMULATE_INTTYPES)
#      define EMULATE_INTTYPES
#endif
#ifndef EMULATE_INTTYPES
#     include
#else
      typedef signed char    int8_t;
      typedef signed short int16_t;
      typedef signed int     int32_t;
      typedef unsigned char    uint8_t;
      typedef unsigned short uint16_t;
      typedef unsigned int     uint32_t;
#     ifdef CONFIG_WIN32
          typedef signed __int64     int64_t;
          typedef unsigned __int64 uint64_t;
#     else /* other OS */
          typedef signed long long     int64_t;
          typedef unsigned long long uint64_t;
#     endif /* other OS */
#endif /* EMULATE_INTTYPES */

错误二： error C3861: “UINT64_C”: 找不到标识符
解决方法：在common.h中添加如下代码：

#ifndef INT64_C
#define INT64_C(c) (c ## LL)
#define UINT64_C(c) (c ## ULL)
#endif
