The VLC app for Android has allowed you to stream videos across your network for a while, but it always required a direct link to the file. Now, the latest beta allows you to browse your folders on shared devices.
The update allows users to browse files over UPnP, NFS, FTP, SFTP, SMB, Windows Shares and a few other protocols. The beta is now available to testers of the VLC Beta which you can join here. In addition to the file browsing, users can also choose to switch from the usual Android interface to the Android TV-style design.
