用反应天然博览会（库：反应式视觉相机）立即使用两个摄像机（前后）

Question

仅一个相机一次使用以下代码。我已经阅读了一些旧文章，说这是不可能的，所以我想问一下是否仍然不可能，因为我的手机的相机应用程序可以做到这一点，所以我知道有某种方法。

import {
  useCameraDevices,
  Camera,
  useCameraDevice,
  useCameraPermission,
} from "react-native-vision-camera";
import { View, Button, Text } from "react-native";
import { useEffect, useState } from "react";

const DualCameraScreen = () => {
  const device1 = useCameraDevice("front");
  const device2 = useCameraDevice("back");
  const { hasPermission, requestPermission } = useCameraPermission();
  const [isRecording, setIsRecording] = useState(false);

  if (!hasPermission) {
    requestPermission();
  }

  const startRecording = async () => {
    setIsRecording(true);
  };

  return (
    <View style={{ flex: 1 }}>
      {device1 && device2 && (
        <View
          style={{ flex: 1, flexDirection: "column", backgroundColor: "green" }}
        >
          <Camera
            style={{ flex: 1 / 3, width: "100%" }}
            device={device1}
            isActive={true}
            video={true}
          />
          <Camera
            style={{ flex: 1 / 3, width: "100%" }}
            device={device2}
            isActive={true}
          />
        </View>
      )}
    </View>
  );
};

export default DualCameraScreen;
