Get the total playtime of your media library
About two years ago I started hosting my own media library on a NAS. Since then I collected and digitized a lot of my DVD and Blu-ray collection. Now during the holidays I was wondering: How much playtime do I have in my library? This consisted of a three-part Problem: How can I recursively find all relevant media files in a directory, since the structure is often nested with subdirectories? How do I extract the playtime of each file?...
