javascript - 检查视频是否正在流式传输

Question

我有来自 http://www.tpai.tv/live 的流但正如您现在看到的，它已关闭，我需要检查流是否正在播放，如果没有播放其他内容。

这是流式传输代码:

<base href="http://www.jet7angola.com/entretenimento/tpa-internacional-online-directo.html">
<script src="http://www.jet7angola.com/tpa/jquery-1.6.2.min.js" type="text/javascript"></script>

<div align="justify" id="livemedia" style="width: 621px; height: 384px;">
    <script type="text/javascript">
    jwplayer("livemedia").setup({"skin":"http://www.tpai.tv/swf/jwplayer/skins/nacht/nacht.zip","id":"livemediaplayer","autostart":"true","rtmp.subscribe":"true","file":"http://www.tpai.tv/tpai_rtmp_dynamic_streaming.xml","controlbar":"none","volume":100,"width":"100%","height":"100%","modes":[{type:"flash",src:"http://www.tpai.tv/swf/jwplayer/player.swf"}]});
    </script>
</div>

更新...

            <div align="justify" id="livemedia" style="width: 621px; height: 384px;">
                <script type="text/javascript">

                .onReady(function(){

                    if(this.getState() == "playing"){
                        jwplayer("livemedia").setup({"skin":"http://www.tpai.tv/swf/jwplayer/skins/nacht/nacht.zip","id":"livemediaplayer","autostart":"true","rtmp.subscribe":"true","file":"http://www.tpai.tv/tpai_rtmp_dynamic_streaming.xml","controlbar":"none","volume":100,"width":"100%","height":"100%","modes":[{type:"flash",src:"http://www.tpai.tv/swf/jwplayer/player.swf"}]});
                    } else {
                        <embed style="vertical-align: middle;width:100%;height:100%;" type="application/x-shockwave-flash" pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://www.rtp.pt/play/player.swf?v3" id="obj_player_prog" name="obj_player_prog" quality="high" allowfullscreen="true" wmode="opaque" allowscriptaccess="always" allownetworking="all" class="embed-responsive-item" flashvars="streamer=rtmp://rtppullswflivefs.fplive.net/rtppullswflive-live&amp;file=2ch27h264&amp;image=undefined&amp;controlbar=over&amp;skin=http://www.rtp.pt/swfjs/skin/fk.zip&amp;autostart=true&amp;plugins=http://programas.rtp.pt/play/ova-jw-play.swf,timeslidertooltipplugin-3&amp;stretching=exactfit&amp;config=http://www.rtp.pt/services/rtpplay/pub/config_page_play/566651108/rtp-play/direto/canais-tv/rtpafrica&amp;abouttext=© RTP.PT&amp;screencolor=0x000000&amp;aboutlink=http://www.rtp.pt/">
                    }    
                });

                </script>
            </div>  

Answer 1

您需要使用 getState() 返回播放器的当前播放状态:

jwplayer("livemedia").setup({

    // Setup parameters

}).onReady(function(){

    if(this.getState() == "playing"){
        // WOO HOO: (Don't cross the streams!)
    } else {
        //THE STREAM IS DOWN!
    }    
});

可用的选项有:

• 空闲:播放尚未开始或播放已停止(由于 stop() 调用或错误)。播放或错误图标 在显示屏上可见。
• 缓冲:用户按下播放，但必须先加载足够的数据才能开始播放。缓冲图标在 展示。
• 正在播放:视频当前正在播放。显示屏上看不到任何图标。
• 暂停:视频当前暂停。播放图标在显示屏上可见。
