海康JAVA二次开发 RTSP转WebRTC播放 springboot的代码

以下是一个基于Spring Boot的RTSP转WebRTC播放的示例代码：

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.web.socket.WebSocketHandler;
import org.springframework.web.socket.config.annotation.EnableWebSocket;
import org.springframework.web.socket.config.annotation.WebSocketConfigurer;
import org.springframework.web.socket.config.annotation.WebSocketHandlerRegistry;
import org.springframework.web.socket.server.standard.ServletServerContainerFactoryBean;

@SpringBootApplication
@EnableWebSocket
public class App implements WebSocketConfigurer {

    public static void main(String[] args) {
        SpringApplication.run(App.class, args);
    }

    @Override
    public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
        registry.addHandler(rtspToWebRTCWebSocketHandler(), "/rtsp-to-webrtc");
    }

    @Bean
    public WebSocketHandler rtspToWebRTCWebSocketHandler() {
        return new RTSPToWebRTCWebSocketHandler();
    }

    @Bean
    public ServletServerContainerFactoryBean createWebSocketContainer() {
        ServletServerContainerFactoryBean container = new ServletServerContainerFactoryBean();
        container.setMaxBinaryMessageBufferSize(1024 * 1024);
        return container;
    }
}

该代码创建了一个Spring Boot应用程序，启用Web套接字，并为RTSP到WebRTC转换处理程序注册了一个Web套接字处理程序。还配置了一个WebSocket容器，用于控制传入消息的缓冲区大小。

下面是RTSPToWebRTCWebSocketHandler类的示例代码：

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.socket.BinaryMessage;
import org.springframework.web.socket.CloseStatus;
import org.springframework.web.socket.WebSocketSession;
import org.springframework.web.socket.handler.BinaryWebSocketHandler;

public class RTSPToWebRTCWebSocketHandler extends BinaryWebSocketHandler {

    private static final Logger log = LoggerFactory.getLogger(RTSPToWebRTCWebSocketHandler.class);

    @Override
    public void afterConnectionEstablished(WebSocketSession session) throws Exception {
        log.info("WebSocket connection established");
    }

    @Override
    public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
        log.info("WebSocket connection closed");
    }

    @Override
    protected void handleBinaryMessage(WebSocketSession session, BinaryMessage message) throws Exception {
        // TODO: Implement RTSP to WebRTC conversion logic
    }
}

该类继承自Spring框架的BinaryWebSocketHandler类，并覆盖了afterConnectionEstablished、afterConnectionClosed和handleBinaryMessage方法。afterConnectionEstablished和afterConnectionClosed方法分别在WebSocket连接建立和关闭时被调用。handleBinaryMessage方法用于处理从WebSocket客户端接收到的二进制消息，并执行RTSP到WebRTC转换逻辑。

需要注意的是，在handleBinaryMessage方法中，需要实现RTSP到WebRTC的转换逻辑。在实际开发中，可能需要使用第三方库或工具来实现这一功能。
