Unsolved Two webcams and their audio
-
I have two Logitech BRIO webcams and can readily switch between them by selecting their unique deviceId. Here is the QML code for context
import QtQuick 2.9 import QtMultimedia 5.12 Rectangle { property int camIndex: 0 property string dutId: "" onDutIdChanged: { var camId = camera.deviceId if(dutId == camId) { console.log("*** match for: " + camId) } } Camera { id: camera captureMode: Camera.CaptureStillImage deviceId: QtMultimedia.availableCameras[camIndex].deviceId videoRecorder { resolution: "1280x720" frameRate: 30 } } }
However, the audio source for each webcam must be found independently. I can enumerate the audio devices using QAudioDeviceInfo, but they identify only as
Logitech BRIO
Logitech BRIOQuestion 1: How to know which audio device belongs to each webcam microphone?
Question 2: How to switch webcam and audio together?
The QAudioRecorder class has helpful availableInputs() and setActiveInput(), methods, but the QCamera and QMediaRecorder classes do not. I suspect that I need to find a QMediaService from which I can get a QAudioInputSelectorControl. However I have failed to make it work.
Any suggestions?

Hi and welcome to devnet,
What OS are you running on ?
-
MacOS, but I like cross-platform solutions.

Each platform returns different informations hence the need to know on which one you are working.
Can you check what you have in the Sound part of the System Settings ?
