Question

我实际上有一个applescript，其中提示要求文件夹来获取该文件夹中视频的总持续时间，但是我想通过右键单击该文件夹并选择我的服务来将此AppleScript作为“服务”工作该文件夹中所有视频的持续时间。在那种情况下，我知道如何从脚本服务。所以请帮助我的朋友们。

--set start_time to (time of (current date)) -- start timing

set this_folder to (choose folder with prompt "Pick the folder containing the video files to process:") as string

保存服务
在Finder中选择一个文件夹并从上下文菜单中运行服务

注意：您必须在

中检查字符串"0"而不是整数0

if this_file_duration_in_seconds is not "0" then

因为shell脚本始终返回字符串，而is not 0将始终评估为true

需要使用applescript来获取所选文件夹
