Back in 2010, I gave a talk about the use of OpenGL shaders to accelerate image and video processing on mobile devices. The response from that talk was strong enough that two years later I started work on the open source framework GPUImage with the goal of making this kind of processing more accessible to developers. In an attempt to broaden the reach of this framework, today I'm introducing the completely-rewritten-in-Swift GPUImage 2 with support for Mac, iOS, and now Linux. This isn't just a port, it's a complete rewrite of the framework.
Read on for how GPUImage 2 differs from the previous iteration, and why I rebuilt it from scratch.
