Flash AV Software Corp has a FFMPEG based component for Delphi XE5 Firemonkey that has a lot of features you can use on IOS. One of the notable features I see in their feature list is the option to play back multiple videos at the same time. It also allows you to play a video from a memory stream, HTTP connection, HTTPS connection, and MMS. Additionally it supports video and audio filters. It will allow you to poll Shoutcast meta data and even resume video playback after receiving a phone call. This seems like a professional component for when you need to do video right on IOS and the price of it reflects that. It supports both Iphone 4, IPad 2, and Iphone 5 which are armv7 and armv7s. It also comes with a free trial so you can test out the performance of it before you buy.
