what does AVMediaTypeMuxed mean?
ios
Solution
mux is a shortened version of multiplex; muxed media is therefore media where multiple streams have been combined together into a single stream — usually that means audio and video streams are combined into a single byte stream.
I would therefore be unsurprised if there's no default multiplexed media output device, as Apple may simply have decided that the default inputs are the cameras and the microphone separately.
Problem
Simple question: what does `AVMediaTypeMuxed` mean? I'm looking at some sample code (below) and it doesn't return anything on my iPad 2. So is `AVMediaTypeMuxed` a device media type that only exists on the iPhone? ``` AVCaptureDevice *muxedDevice = [AVCaptureDevice defaultDeviceWithMediaType: AVMediaTypeMuxed]; if (muxedDevice) { NSLog (@"got muxedDevice"); AVCaptureDeviceInput *muxedInput = [AVCaptureDeviceInput deviceInputWithDevice:muxedDevice error:&setUpError]; if (muxedInput) { [captureSession addInput:muxedInput]; } } ```
