I’m going to assume that you have already followed all of the steps in Day 5 to get the sample code up and running. As before, I’ll provide all the code to get it working, and then we’ll talk through it. You can see all this happening in the code below. This has the benefit of not only changing the video feed sent to the call (if the call is connected) but also updating the local vanity feed automatically. For anyone who has previously had to deal with WebRTC, you’ll recognise this is a significantly easier process.įor video devices, there is a method on the LocalVideoStream object called switchSource which we can use. Each of these can have different values, and these values can be changed mid-call.Īudio devices in Azure Communication Services are changed by making a call to the DeviceManager, which then handles the actual switching of audio. When we talk about audio and video devices, there are actually three different devices we are changing: the video feed, the microphone and the speaker. You could add these to any of the samples we’ve previously made – but the Teams meeting one means it’s easy for you to create a Teams meeting and join it using the Teams client, and then join with an ACS client and toggle the video and audio devices then see and hear the effect using the other client.

Today, we’re going to take the Day 8 sample (which joins an ACS client to a Teams meeting), plus the video features we added in Day 10, and add the ability to change audio and video devices. The series covers a high-level overview of capabilities and considerations, then dives into the development detail of using ACS in your application. Find the rest of the posts in the series at v. In JavaScript, the MediaDevices.enumerateDevices() method can be used to enumerate the media devices and find a device ID to pass to fromMicrophone(.).This blog post is part of a series called “ Learn ACS“, all about Microsoft Azure Communication Services.

Hr = pProps->GetValue(PKEY_Device_FriendlyName, &varName) Get the endpoint's friendly-name property. Initialize the container for property value. Each iteration prints the name of an endpoint device. Hr = pEnumerator->EnumAudioEndpoints(eCapture, DEVICE_STATE_ACTIVE, &pCollection) Hr = CoCreateInstance(CLSID_MMDeviceEnumerator, NULL, CLSCTX_ALL, IID_IMMDeviceEnumerator, (void**)&pEnumerator) and endpoint ID string of each endpoint device. This function enumerates all active (plugged in) audio
