Android '；安全队列.h'；在我的项目中找不到文件 背景

我尝试构建一个支持ffmpeg的android应用程序来播放本地视频文件。但我对一个陌生的问题感到困惑

问题 我编写代码：

#include "safe_queue.h"

包括SafeQueue，但IDE显示未找到“safe\u queue.h”文件。

我是一名C/C++编程新手，我不知道这有什么问题，发生了什么，以及如何修复它。此外，如果我将来遇到类似的问题，我该如何解决它

有人能帮我吗，或者讨论一下我的代码出了什么问题。谢谢

谢谢@Damien！

最后，我检查了代码，发现“SuffyQueal.h”不是C++标准。我使用STD:：队列代替。< /P>我的理解是：<代码> SuffyQueal.H./C> >不是C++标准的一部分。你必须安装/下载它。@Damien谢谢你的建议，我试着安装/下载它。。。
