<div class="main">
        <video id="videoElement" class="centeredVideo" controls autoplay width="1024" height="576">Your browser is too old which doesn't support HTML5 video.</video>
    </div>
    <br>
    <div class="controls">
        <!--<button onclick="flv_load()">加载</button>-->
        <button onclick="flv_start()">开始</button>
        <button onclick="flv_pause()">暂停</button>
        <button onclick="flv_destroy()">停止</button>
        <input style="width:100px" type="text" name="seekpoint" />
        <button onclick="flv_seekto()">跳转</button>
    </div>

js

<script>
        var player = document.getElementById('videoElement');
        if (flvjs.isSupported()) {
            var flvPlayer = flvjs.createPlayer({
                type: 'flv',
                url: '你的视频.flv'
            });
            flvPlayer.attachMediaElement(videoElement);
            flvPlayer.load(); //加载
        }

        function flv_start() {
            player.play();
        }

        function flv_pause() {
            player.pause();
        }

        function flv_destroy() {
            player.pause();
            player.unload();
            player.detachMediaElement();
            player.destroy();
            player = null;
        }

        function flv_seekto() {
            player.currentTime = parseFloat(document.getElementsByName('seekpoint')[0].value);
        }
    </script>
