+
+> Git a list of avialable audio and video devices from ffmpeg
+
+# WARNING
+
+Currently this only works on mac. If you want this to work on another platform, that is coming eventually, and PR's are welcome!
+
+## Install
+
+```
+$ npm install --save ffmpeg-devices
+```
+
+
+## Usage
+
+```js
+const ffmpegDevices = require('ffmpeg-devices');
+
+ffmpegDevices();
+// => {
+// 	audio: [], // audio devices
+// 	video: [], // video devices
+// 	unknown: [] // unknown devices
+// }
+
+// If you want to use a specific bin
+ffmpegDevices('<path to ffmpeg binary>')
+
+// can specify an input to parse if you would prefer
+ffmpeg(null, {
+	ffmpegOutput: `some output to parse` // ffmpeg should not be called in this case.
+})
+```
