# Introduction Mellow-ffmpeg is a Haskell library providing a layer over [ffmpeg-light](https://github.com/acowley/ffmpeg-light), [friday](https://github.com/RaphaelJ/friday), and [gloss](http://gloss.ouroborus.net/). That is, Mellow acquires RGBA frames from the web camera, applies the user-provided image transformation, and renders the image to screen. The main routine is `mellow state0 update render eventHandler` where `state0` is the initial state, update will update the state with a new frame, `render` will rasterize a given state for display to screen, and `eventHandler` is useful for key presses and other inputs. # Example In under 20 lines we can get a pretty little OpenGL colored rendering of the image edges. The basic steps are: 1. Import Mellow and 'friday'. Import 'gloss' as needed. 2. Call 'mellow' with desired call backs for receiving a new frame into your state, rendering the state, and handling keyboard events (see 'gloss' documentation for keyboard events). 3. Define your callback that transforms RGBA images into RGBA images using whatever techniques you desire (see the 'friday' library). For example, see the [canny demo](examples/EdgeDetect.hs).
