What is this?
A tiny browser module that gives us a simple API for getting access to a user's screen. It uses https://github.com/otalk/getUserMedia.
It gives us a cleaner node.js-style, error-first API and cross-browser handling. No browser support checking necessary; lack of support is treated in the same way as when the user rejects the request: the callback gets passed an error as the first argument.
Suitable for use with browserify/CommonJS on the client.
If you're not using browserify or you want AMD support use
getscreenmedia.bundle.js. Note that if no module system is detected it will attach a function called
npm install getscreenmedia
How to use it
Use the snippet below to get a screen stream, similar to getUserMedia.
var getScreenMedia = ;;
All supported browsers require the use of an extension and don't offer an cross-browser API which is annoying and error-prone. Node-style (error-first) APIs that are cross-browser, installable with npm and runnable on the client === win!
Error handling (denied requests, etc) are handled mostly by the underlying getUserMedia lib. However this adds one more error type:
Because that's a current requirement of Chrome.
See the handling errors section of the getUserMedia lib for details about how errors are handled.
