react-native-video: Why does the app become slow on Andriod when I use react-native-video?

Why does the app become slow on Andriod when I use react-native-video? The prop.video is a local file URL, I’m using React Native new arch With the latest version of react-native-video ^6.0.0-alpha.7. On iOS I noticed it’s OK. But on Andriod both emulator and real device. It’s not smooth as other apps like TikTok and Instagram are when is comes to video.

import { Dimensions, StyleSheet, View } from 'react-native'
import React from 'react'
import Video from 'react-native-video';

type Props = {
  video: string
}

const { height, width } = Dimensions.get('window');

const Video = (props: Props) => {

  return (
    <View style={{ backgroundColor: 'gray' }}>
      <Video
        source={{ uri: props.video }}
        resizeMode="cover"
        repeat
        paused={true}
        style={styles.backgroundVideo} />
    </View>
  );
}

export default Video;

const styles = StyleSheet.create({
  backgroundVideo: {
    height,
    width,
  },
});
