VideoLAN’s VLC player is a great cross platform media player, it will play just about any video format and is available on Android, Mac, Windows and Linux. It was available for iOS a couple of years ago, the app was in the store for just over a month before it was pulled due to open source licensing issues but now it’s back.
As well as being able to play a whole range of video formats the app will play content from network streams, from a web server, integrates with Dropbox and supports WiFi uploading. Its great to see the app back in the store, it’s a very versatile app and its completely free.
Download the app from the iTunes Store.
