Infuse is an amazing app for iOS users which allows you to stream video files from Bitport on your iOS device. There are plenty of useful features including a short description of each video file, the ability to load subtitles or download videos for offline viewing. The basic version of Infuse is for free. The premium version lets you play .mkv files with AC3 codec and stream videos to Apple TV and Chromecast. This guide covers FTP, but these steps work for SFTP as well. Just use URL sftp.bitport.io and port 2022 instead.
