有没有办法从 Mac 上的 TV（即 iTunes）应用程序中获取电影信息？我说的不是“mdls”中的技术信息；我说的是应用程序信息框中的信息：即导演、演员、剧组人员等。这些信息肯定在系统的某个地方，那么我该如何获取它呢？
答案1
我认为您可以使用 AppleScript 来实现这一点，它的好处是可以直接与 iTunes 对话，但通过命令行以这种方式使用它并不那么容易。
如果你想要命令行访问，我强烈推荐MP4工具。我认为你需要自己编译它，除非有它的“端口”（MacPorts）或 Homebrew。你也可以使用 ffprobe，它是 ffmpeg 套件的一部分，你绝对可以通过 MacPorts 和/或 Homebrew 获得它，我忘了我使用的是哪个了。

ffprobe 的输出：

Long Description: One of the screen's grandest epics, this monumental story recounts the true-life experiences of T.E. Lawrence, better known to the world as Lawrence of Arabia. A young, idealistic British officer in WWI, Lawrence (Peter O'Toole) is assigned to the camp of Prince Feisal (Alec Guinness), an Arab tribal chieftain and leader in a revolt against the Turks. In a series of brilliant tactical maneuvers, Lawrence leads fifty of Feisal's men in a tortured three-week crossing of the Nefud Desert to attack the strategic Turkish-held port of Aqaba. And following his successful raids against Turkish troops and trains, Lawrence's triumphant leadership and unyielding courage gain him nearly god-like status among his Arab brothers.
