解决:Cannot open include file: 'inttypes.h'
更新ffmpeg之后,有时编译应用ffmpeg库的工程会发现提示: Cannot open include file: 'inttypes.h': No such file or directory 的出错信息,可通过如下方法解决:
1、找到include目录中的ffmpeg\common.h
2、在“#define COMMON_H”之后加入如下代码,同时删除“#include <inttypes.h>” 然后保存:
#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 <inttypes.h>
#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 */
解决 error C3861: 'UINT64_C': identifier not found
#ifndef INT64_C
#define INT64_C(c) (c ## LL)
#define UINT64_C(c) (c ## ULL)
#endif
ffmpeg.exe初始化出错
如果你编译的ffmpeg.exe运行时,出现“应用程序正常初始化(0xc0000005)失败”(The application failed to initialize properly (0x0000005). Click on OK to terminate the application),而且是shared link方式,通常的原因是GCC的版本问题,更换一个GCC的版本应该可以解决该问题。
下载一份gcc-core-4.2.1-sjlj-2.tar.gz,然后解压缩 进入mingw\bin目录,通常是:C:\msys\mingw\bin\ 然后重命名下述文件: c++-sjlj.exe to c++.exe cpp-sjlj.exe to cpp.exe g++-sjlj.exe to g++.exe gcc-sjlj.exe to gcc.exe 然后再重新编译,通常可以解决该问题。
