To create a weather video with a CNN background and add a recipe PNG, you can use the react-native-compressor library to compress images and videos. Here's a brief snippet to get you started:

import React from 'react';
import { View, Image } from 'react-native';
import Compress from 'react-native-compressor';

const WeatherVideo = () => {
  const compressImage = async (image) => {
    const compressedImage = await Compress.compress(image, {
      format: 'png',
      quality: 0.5,
    });
    return compressedImage;
  };

  const compressVideo = async (video) => {
    const compressedVideo = await Compress.compress(video, {
      format: 'mp4',
      quality: 0.5,
    });
    return compressedVideo;
  };

  return (
    <View>
      <Image
        source={{ uri: 'https://example.com/weather-image.png' }}
        style={{ width: 300, height: 200 }}
      />
      <Compress.Image compress={compressImage} />
      <Compress.Video compress={compressVideo} />
      <Image
        source={{ uri: 'https://example.com/recipe-png.png' }}
        style={{ width: 100, height: 100 }}
      />
    </View>
  );
};

export default WeatherVideo;

This code snippet uses the react-native-compressor library to compress images and videos. You'll need to replace the image and video URLs with your own assets.

Note that this is just a basic example, and you may need to adjust the compression settings and image/video formats to suit your specific requirements.
