Universal Video Downloader is a jailbreak tweak that allows you to extract video from any app. It’s a tweak that makes it totally feasible to download an iTunes trailer, or other video content for offline use.

Obviously, as with any app of this nature, it is possible to use it for more unscrupulous means, but as we always do at iDB, we urge you to use the app like it was intended to be used — for legitimate purposes. Want to see how it works? Take a look inside as we take Universal Video Downloader for a spin.

Universal Video Downloader “listens” in the background, and will pop up a notification anytime it senses a video playing within another app. It will then prompt you to download that video to your library. As you’ll see in the demonstration above, not all videos will play within your library, so you may have to use iFile in order to access the content.

Fortunately, content like Netflix, although it can be watched offline within the app, isn’t shareable, or even watchable outside of Universal Video Downloader. This will, hopefully, prevent people from downloading streaming content like Netflix for devious reasons.

Universal Video Downloader can be had for free on Cydia’s BigBoss repo. Let us know what you think about it in the comments below.
