VS2010 Release ctrl+F5 运行、双击EXE运行、F5运行 结果不一致

[氰客]

环境： WIN7、VS2010 、FFMPEG
操作：调用 FFMPEG av_probe_input_buffer 接口探测网络视频流格式

  
  if ((ret = av_probe_input_buffer(pb, &piFmt, "", NULL, 0, 0)) < 0) 
    {
        char buffer[256]= {};
        av_make_error_string(buffer, 256, ret);
        fprintf(stderr, "probe failed![%x:%s][ret = %d]\n",piFmt, buffer,  ret);
        return ret;
    }

现象：在工程下运行（F5 | CTRL+F5），debug，release均正常，双击运行，Debug正常，release调用报错

probe failed![0:Invalid data found when processing input][ret = -1094995529]

配置：该模块为单独DLL，被上层EXE加载调用，代码生成方式为/MT（/MD生成时 release下 CTRL+F5运行也会报同样的错）

求大神指点啊，毫无头绪！

_getcwd, _wgetcwd Get the current working directory. char *_getcwd( char *buffer, int maxlen ); wchar_t *_wgetcwd( wchar_t *buffer, int maxlen ); Routine Required Header Compatibility _getcwd <direct.h> Win 95, Win NT _wgetcwd <direct.h> or <wchar.h> Win NT For additional compatibility information, see Compatibility in the Introduction. Libraries LIBC.LIB Single thread static library, retail version LIBCMT.LIB Multithread static library, retail version MSVCRT.LIB Import library for MSVCRT.DLL, retail version Return Value Each of these functions returns a pointer to buffer. A NULL return value indicates an error, and errno is set either to ENOMEM, indicating that there is insufficient memory to allocate maxlen bytes (when a NULL argument is given as buffer), or to ERANGE, indicating that the path is longer than maxlen characters. Parameters buffer Storage location for path maxlen Maximum length of path in characters: char for _getcwd and wchar_t for _wgetcwd Remarks The _getcwd function gets the full path of the current working directory for the default drive and stores it at buffer. The integer argument maxlen specifies the maximum length for the path. An error occurs if the length of the path (including the terminating null character) exceeds maxlen. The buffer argument can be NULL; a buffer of at least size maxlen (more only if necessary) will automatically be allocated, using malloc, to store the path. This buffer can later be freed by calling free and passing it the _getcwd return value (a pointer to the allocated buffer). _getcwd returns a string that represents the path of the current working directory. If the current working directory is the root, the string ends with a backslash ( \ ). If the current working directory is a directory other than the root, the string ends with the directory name and not with a backslash. _wgetcwd is a wide-character version of _getcwd; the buffer argument and return value of _wgetcwd are wide-character strings. _wgetcwd and _getcwd behave identically otherwise. Generic-Text Routine Mappings TCHAR.H Routine _UNICODE & _MBCS Not Defined _MBCS Defined _UNICODE Defined _tgetcwd _getcwd _getcwd _wgetcwd Example // GETCWD.C /* This program places the name of the current directory in the * buffer array, then displays the name of the current directory * on the screen. Specifying a length of _MAX_PATH leaves room * for the longest legal path name. */ #include <direct.h> #include <stdlib.h> #include <stdio.h> void main( void ) { char buffer[_MAX_PATH]; /* Get the current working directory: */ if( _getcwd( buffer, _MAX_PATH ) == NULL ) perror( "_getcwd error" ); else printf( "%s\n", buffer ); } Output C:\code Directory Control Routines See Also _chdir, _mkdir, _rmdir _chdir, _wchdir Change the current working directory. int _chdir( const char *dirname ); int _wchdir( const wchar_t *dirname ); Routine Required Header Optional Headers Compatibility _chdir <direct.h> <errno.h> Win 95, Win NT _wchdir <direct.h> or <wchar.h> <errno.h> Win NT For additional compatibility information, see Compatibility in the Introduction. Libraries LIBC.LIB Single thread static library, retail version LIBCMT.LIB Multithread static library, retail version MSVCRT.LIB Import library for MSVCRT.DLL, retail version Return Value Each of these functions returns a value of 0 if successful. A return value of –1 indicates that the specified path could not be found, in which case errno is set to ENOENT. Parameter dirname Path of new working directory Remarks The _chdir function changes the current working directory to the directory specified by dirname. The dirname parameter must refer to an existing directory. This function can change the current working directory on any drive and if a new drive letter is specified in dirname, the default drive letter will be changed as well. For example, if A is the default drive letter and \BIN is the current working directory, the following call changes the current working directory for drive C and establishes C as the new default drive: _chdir("c:\\temp"); When you use the optional backslash character (\) in paths, you must place two backslashes (\\) in a C string literal to represent a single backslash (\). _wchdir is a wide-character version of _chdir; the dirname argument to _wchdir is a wide-character string. _wchdir and _chdir behave identically otherwise. Generic-Text Routine Mapping: TCHAR.H Routine _UNICODE & _MBCS Not Defined _MBCS Defined _UNICODE Defined _tchdir _chdir _chdir _wchdir Example /* CHGDIR.C: This program uses the _chdir function to verify * that a given directory exists. */ #include <direct.h> #include <stdio.h> #include <stdlib.h> void main( int argc, char *argv[] ) { if( _chdir( argv[1] ) ) printf( "Unable to locate the directory: %s\n", argv[1] ); else system( "dir *.wri"); } Output Volume in drive C is CDRIVE Volume Serial Number is 0E17-1702 Directory of C:\write 04/21/95 01:06p 3,200 ERRATA.WRI 04/21/95 01:06p 2,816 README.WRI 2 File(s) 6,016 bytes 71,432,116 bytes free Directory Control Routines See Also _mkdir, _rmdir, system

我的回复是提醒你两种运行方法的当前目录不一样。

所使用的DLL都是一样的啊。

Debug在目录下直接运行和在工程里运行结果是一致的。

[赵4老师]

和exe文件同一目录下的.manifest文件关注一下。

沉了，求指点解决思路啊。
