iOS摄像头硬件操作需要越狱并开发内核扩展模块。Android平台可通过Camera2 API实现虚拟摄像头功能，但iOS系统限制严格，建议在MacOS开发环境测试视频流处理功能。

VirtualCamera.java

import java.awt.image.BufferedImage;

import java.nio.ByteBuffer;

public class VirtualCamera {

private static final int WIDTH = 1920;

private static final int HEIGHT = 1080;



public ByteBuffer generateTestPattern() {

    BufferedImage image = new BufferedImage(WIDTH, HEIGHT, 

        BufferedImage.TYPE_3BYTE_BGR);

    

    for(int y=0; y<HEIGHT; y++) {

        for(int x=0; x<WIDTH; x++) {

            int r = (x*y) & 0xFF;

            int g = (x*2) % 0xFF;

            int b = (y*2) % 0xFF;

            image.setRGB(x, y, (r << 16) | (g << 8) | b);

        }

    }

    

    byte[] buffer = new byte[WIDTH*HEIGHT*3];

    int index = 0;

    for(int y=0; y<HEIGHT; y++) {

        for(int x=0; x<WIDTH; x++) {

            int rgb = image.getRGB(x, y);

            buffer[index++] = (byte)((rgb >> 16) & 0xFF);

            buffer[index++] = (byte)((rgb >> 8) & 0xFF);

            buffer[index++] = (byte)(rgb & 0xFF);

        }

    }

    return ByteBuffer.wrap(buffer);

}

}

            Socket client = server.accept();

            new Thread(() -> {

                try {

                    ByteBuffer frame = virtualCam.generateTestPattern();

                    client.getOutputStream().write(frame.array());

                    client.close();
