I've been using Infuse on iPhones, IPads, and Apple TVs for more than 5 years and it is simply the best way to stream videos files locally, from local NAS machines, or across the internet via Plex that there is. The codec support, audio support, customization, and continued development of the app is out of this world. The adage "you get what you pay for" has never been more true than with Infuse with a Pro subscription.
