Hey there! To get a specific camera working in LiveKit and sort out any permission hiccups, here’s a simple way to do it: 1. Set the Camera ID: Just use the

setDeviceId

method from the

LocalVideoTrack

class to pick the camera you want. Like this:

localVideoTrack?.setDeviceId("specific_camera_id")

2. Request Permissions: Make sure your app asks for

CAMERA

and

RECORD_AUDIO

permissions before trying to use the camera. You can handle this smoothly with `ActivityResultContracts.RequestMultiplePermissions`:

private fun requestPermissions() {
    val requestPermissionLauncher = registerForActivityResult(
        ActivityResultContracts.RequestMultiplePermissions()
    ) { grants ->
        for (grant in grants.entries) {
            if (!grant.value) {
                Toast.makeText(this, "Missing permission: ${grant.key}", Toast.LENGTH_SHORT).show()
            }
        }
    }

    val neededPermissions = listOf(Manifest.permission.RECORD_AUDIO, Manifest.permission.CAMERA)
        .filter {
            ContextCompat.checkSelfPermission(this, it) == PackageManager.PERMISSION_DENIED
        }
        .toTypedArray()

    if (neededPermissions.isNotEmpty()) {
        requestPermissionLauncher.launch(neededPermissions)
    }
}

Just double-check that permissions are all set before turning on the camera. And if anything still feels off, try using

MediaDeviceFailure.getFailure(error)

to get to the bottom of any specific permission issues. You’ve got this! Sources: livekit-android-camerax/src/main/java/livekit/org/webrtc/CameraXSession.kt | sample-livestream/src/main/java/io/livekit/android/sample/livestream/ui/scr... | README.md
