64位计算机上的avistreamgetframeopen错误 [英] avistreamgetframeopen error on a 64 bit machine

问题描述

我不确定这是正确的论坛，但无论如何我都会尝试。我有一个使用vfw的avi阅读应用程序，当编译为32位目标时，它可以在64位机器上正常工作。但是，当我为x64编译时，AVI文件打开正常，并且可以从中提取
数据（例如宽度，高度和帧数）。但是，当我调用avistreamgetframeopen时，它返回NULL。我不太确定为什么，如果有人可以提供帮助，我将不胜感激。

I am not sure is this is the right forum to ask, but I'll try anyway. I have an avi reading application which uses vfw, which works fine on a 64 bit machine when compiled for a 32 bit target. However, when I compile for x64, the AVI file opens fine, and data can be extracted from it (such as width, height and number of frames). However, when I call avistreamgetframeopen it returns NULL. I am not really sure why, and if anyone could help, it would be much appreciated.

谢谢！

which version of Vfw32.lib used for linking? It should be x64 version might be located c:\Program Files\Microsoft SDKs\Windows\v6.1\Lib\x64\Vfw32.lib.
