java实现监控rtsp流转flv方法实例(前端播放,前后端代码都有)

作者：心起

这篇文章主要给大家介绍了关于java实现监控rtsp流转flv的相关资料,文中介绍的是前端播放,前后端代码都有,文中通过实例代码介绍的非常详细,需要的朋友可以参考下

一.服务代码

maven配置文件引入坐标: 

        <dependency>
            <groupId>org.bytedeco</groupId>
            <artifactId>javacv-platform</artifactId>
            <version>1.5.1</version>
        </dependency>
        <dependency>
            <groupId>javax.xml.bind</groupId>
            <artifactId>jaxb-api</artifactId>
            <version>2.3.0</version>
        </dependency>

二.客户端代码基于flv.js进行播放

        <button onclick="playflv()">点击播放</button>
        <script>
            if (flvjs.isSupported()) {
                var videoElement = document.getElementById('videoElement');
                var flvPlayer = flvjs.createPlayer({
                    type: 'flv',
                    url: 'http://127.0.0.1:10010/xr/flv',
                flvPlayer.attachMediaElement(videoElement);
                flvPlayer.load();
            //自动播放,浏览器不支持
            function playflv() {
                flvPlayer.play();
        </script>
    </body>
</html>


这里因为浏览器把自动播放给禁止了，加了个按钮点击事件
