I am creating a win32 API C++ application with Microsoft Visual Studio 2022 in a .sln file. I've got quite far in basic functionalities & decided to try out video decoding & playing; I've practiced this before but not with C++. So, I looked to see good libraries & found FFmpeg. Of course, I thought this would be quite straightforward - just import the headers & code, right? No. Firstly, the FFmpeg I'm using is one of the pre-built binaries. The 'ffmpeg-master-latest-win64-gpl-shared.zip' From the BtbN Github repository. I decompressed it with WinRar & placed the files in Program Files (x86). Later on, I realised my mistake of placing it with 32-bit programs since it's a 64-bit build. So I transferred it to Program Files. Even after this though my issue persists. The issue being that the .h files of FFmpeg cannot communicate with each other. For some reason, they can't navigate to where the header files are. I am quite sure the reason for this may have something to do with where I save the files, the directory. Nowhere on the FFmpeg website can I see where you're expected to have the file directory at. I am sure there's a preset file path that is expected. Maybe I've named the FFmpeg folder incorrectly? Or maybe it's not meant to go in Program Files? The current directory for the FFmpeg folder for me is: C:\Program Files\FFmpeg. Below I will provide pictures of the errors I get where the code can't connect to other .h files as well as the file path. I'll also provide my code.

我正在使用Microsoft Visual Studio 2022在.sln文件中创建一个win32 API C++应用程序。我在基本功能上已经走得很远了，决定尝试视频解码和播放;我以前练习过这个，但没有用C++。所以，我看了看好的库，找到了FFmpeg。当然，我认为这将是非常简单的-只需导入头和代码，对吗？不。首先，我使用的FFmpeg是预构建的二进制文件之一。The 'ffmpeg-master-latest-win64-gpl-shared.zip'从BtbN Github仓库.我用WinRar解压并将文件放在Program Files（x86）中。后来，我意识到我的错误，把它与32位程序，因为它是一个64位的建设。所以我把它转到了程序文件里即使在这之后，我的问题仍然存在。问题是FFmpeg的.h文件无法相互通信。由于某些原因，它们无法导航到头文件所在的位置。我很确定这可能与我保存文件的位置有关，目录。在FFmpeg网站上，我看不到你应该把文件目录放在哪里。我相信有一个预设的文件路径是预期的。也许我命名的FFmpeg文件夹错误？或者它不应该被放入程序文件中FFmpeg文件夹的当前目录是：C：\Program Files\FFmpeg。下面我将提供图片的错误，我得到的代码不能连接到其他.h文件以及文件路径。我还将提供我的代码。

I severely doubt my code has anything to do with the issue though. It's probably directory-based. I just placed wWinmain here to keep with the character limit.

不过，我严重怀疑我的代码与这个问题有任何关系。它可能是基于目录的。我把wWinmain放在这里只是为了符合字符限制。
