推荐答案

为iOS创建交互式视频的最简单方法是使用Apple的HTTP直播技术。你必须创建一个视频，嵌入元数据，使用 MPMoviePlayerController 或 AVPlayerItem 播放，然后显示可点击区域以响应元数据通知。

The easiest way to create interactive videos for iOS is to use Apple's HTTP Live Streaming technology. You have to create a video, embed metadata, play it using MPMoviePlayerController or AVPlayerItem, and then display clickable areas in response to metadata notifications.

元数据应包含您要跟踪的元素的坐标，例如：连衣裙和产品的标识符。您可以使用可点击的子视图覆盖此信息，该子视图显示有关产品的更多信息。在iTunes中有几种​​此类应用，这里是 one 。

Metadata should contain coordinates for the element you are tracking, eg: a dress, and a identifier for the product. You overlay this info with a clickable subview that reveals more information about the product. There are several applications of this kind in iTunes, here is one.

一旦你获得了一个工作产品和几周的视频，最困难的部分是用尽可能少的人机交互来进行动作跟踪。一种方法是使用Adobe After Effects，另一种方法是基于OpenCV编写自己的解决方案。

Once you get a working product and weeks-time of videos, the most difficult part is to perform motion tracking with the less possible human interaction. One approach is to use Adobe After Effects, another is to code your own solution based on OpenCV.
