ffmpeg退出状态-1094995529

我正在开发一个调用ffprobe的应用程序,它在Windows上为某些文件返回ffprobe的非正统退出状态 。 这个退出状态是一贯的,这里有一些小的讨论 。

为什么给出这个值,在哪里logging? 我可以期望这种状态在unix机器上有所不同,在这种情况下允许的退出状态更受限制?

来自ffmpeg的错误代码(来自avutil的error.h): http ://ffmpeg.org/doxygen/trunk/error_8h_source.html

原来你指定的值是:

 #define AVERROR_INVALIDDATA FFERRTAG( 'I','N','D','A') 

-1094995529变成了-0x41444E49,当你看ACSII中的这些字母时,0x41 ='A',0x44 ='D',0x4E ='N,0x49 ='I'。 由于宏/等东西是相反的,所以ADNI成为INDA,你可以从#define片断看到,是定义为FFERRTAG('I','N','D','A')的AVERROR_INVALIDDATA。

其余的错误代码在该文件中,我在这里粘贴它们:
