使用Xcode 5编译live555和ffmpeg

在我当前的项目中，我们需要在同一个项目中同时使用live555和ffmpeg库。我们能够建立并为这两个项目没有问题，运行样品，但合并这两个项目到遇到以下编译器错误项目时：使用Xcode 5编译live555和ffmpeg

我应该包括所有必需的文件，所以我有点傻眼由此，任何建议是值得欢迎的，谢谢。

是的，你可以很成功地结合起来。我发现最好的方法是创建一个工作空间，合并ffmpeg和live555库。

这里有一个例子。 enter image description here

谢谢，我会再试一次，也许这是我合并时做的傻事。可以肯定的是，你有没有尝试过，看看这是否适用于Xcode 5.0.x？ – Kai

仍然得到相同的错误信息，如果你的项目是live555＆ffmpeg的简单合并，是否有可能将它上传到某处供我下载并尝试？在此先感谢 – Kai

你可以直接联系我，或通过我们的Facebook页面，也许我们可以拿出一些东西https://www.facebook.com/groups/mooncatventures/ –
