In our work, we often need to implement video streaming from iOS devices in real-time or near real-time. A common example is the use of iOS devices as surveillance cameras or creation of streaming applications like Periscope. Problem statement often imposes additional requirements like enabling of stream playback on another device or running the app smoothly in the browser or VLC player, low latency (video streaming in near real-time), low resource consumption (long battery life), no need in a dedicated media server, etc.
In the article we are going to share our experience of finding the optimal way to visualize a waveform in an iOS app, choosing between CAShapeLayer and drawRect(), and certain nuances of using Swift. The publication is targeted at those who create complex custom UI components for sound processing, but also any iOS developers wishing to broaden their horizons. Continue reading
