        Specifies the type of media permission to request.

        Allowed value: Permission

      import { Constants, useMediaDevice } from "@videosdk.live/react-sdk";

      const { checkPermissions } = useMediaDevice();

      try {
        const checkAudioVideoPermission = await checkPermissions();
        console.log(
        "check Audio and Video Permissions",
        checkAudioVideoPermission.get(Constants.permission.AUDIO),
        checkAudioVideoPermission.get(Constants.permission.VIDEO)
        );
      } catch (ex) {
        console.log("Error checking permissions:", ex);
      }

      Note

      This method will throw an error if the browser does not support permission checking functionality.

      • This method can be used to retrieve a list of all currently available media input and output devices.
      • The returned Promise resolves with an array of DeviceInfo objects, or an empty array if the devices could not be listed.

      Returns Promise<DeviceInfo[]>

      • This method can be used to prompt the user for permission to access media input devices.
      • It requests permission for the specified media types and returns the permission status for each requested media kind.

      • Optionalpermissions: Permission

        Specifies the type of media permission to request.

        Allowed value: Permission

      Returns Promise<Map<string, boolean>>

      import { Constants, useMediaDevice } from "@videosdk.live/react-sdk";

      const { requestPermission } = useMediaDevice();

      try {
        const permissionsMap = await requestPermission(
          Constants.permission.AUDIO_AND_VIDEO
        );

        console.log(
          "request Audio and Video Permissions",
          permissionsMap.get(Constants.permission.AUDIO),
          permissionsMap.get(Constants.permission.VIDEO)
        );
      } catch (ex) {

      • This event emits the updated list of available devices after the change has occurred.

      Parameters

      • devices: DeviceInfo[]

        An array of currently available media devices.

      Returns void

      function onDeviceChanged(devices) {
        console.log("onDeviceChanged ", devices);
      }

      const {
        ...

        onDeviceChanged
      });
