c++ - LibVLC Demux 无法查看

Question

我正在尝试使用 LibVLC 最终在更大的应用程序中流式传输视频，但目前我正在处理 tutorial .当前的目标只是流式传输保存在我计算机上的视频

当我用调试器遍历程序时，错误代码

[00000216266e7650] mjpeg demux error: cannot peek

出现在第56行之后:

libvlc_media_player_stop(mp);

视频必须放置在与 main.cpp 相同的位置(而不是我想要的带有显式文件路径的位置)。这是一个 .wmv 文件。

我使用的是 LibVLC 3.0.7.1，它是作为 Visual Studio 的 NuGet 包获得的。我无法从源代码构建 libVLC，因为我 a) 难以使用 Linux 并且无法轻松访问它，b) 无法在 Windows 机器上安装交叉编译所需的所有工具，以及 c) 因为我还是新手对此

添加答案而不是删除答案，以防其他人遇到类似问题。

Sleep() 函数接受以毫秒为单位的时间参数。适本地提高它，它工作正常。
