在FaceTime中设置摄像头的指令

Question

我需要使用AppleScript自动化FaceTime呼叫，但我的要求之一是选择一个特定的网络摄像头。我正在尝试使用这个代码:

tell application "System Events"
tell process "FaceTime"
    tell menu bar 1
        tell menu bar item "Video"
             click menu item "Webcam 520X"
        end tell
    end tell
end tell
end tell

但是我得到了这个错误信息:

系统事件发生错误:无法获取FaceTime进程的菜单栏1的菜单栏项"视频"的菜单项"Webcam 520X"

有什么好的建议吗?谢谢!

在menu item和menu bar item之间总是存在一个menu引用

activate application "FaceTime"
tell application "System Events"
    tell process "FaceTime"
        tell menu bar 1
            tell menu bar item "Video"
                tell menu 1
                    click menu item "Webcam 520X"
                end tell
            end tell
        end tell
    end tell
end tell

或

activate application "FaceTime"
tell application "System Events"
    tell process "FaceTime"
        click menu item "Webcam 520X" of menu 1 of menu bar item "Video" of menu bar 1
    end tell
end tell
