我正在尝试将以下代码从 Objective-C 移植到 Node.js：

[[self.output connectionWithMediaType:AVMediaTypeVideo] setVideoMinFrameDuration: CMTimeMake(1, 30)];

我正在写以下内容：

this.output('connectionWithMediaType', macOS.AVMediaTypeVideo)('setVideoMinFrameDuration', macOS.CMTimeMake(1, 30));

实例macOS在哪里。NodObjC

当我运行它时，我得到以下信息：

应用程序中的其他所有内容都在工作——也就是说，我移植了所有其他代码行并且它正在工作。

谢谢！
