最近在做關於視頻平臺的直播和點播功能，服務端使用的是SRS版本，計劃手機APP使用PLDroidPlayer來通過http-flv的方式實現視頻的直播和點播，Web端可以使用flv.js。目前手機端沒有什麼問題，介紹下使用html5頁面方式通過http-flv來進行視頻的直播和點播，直播和點播都使用flv。
1、在點播的時候，使用yamdi對flv視頻文件添加關鍵幀，然後將視頻文件存儲在nginx服務器上，同樣將html頁面存儲在nginx的目錄下，具體代碼如下：
flvVod.html
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
<title>flv.js demo</title>
<style>
.mainContainer {
display: block;
width: 1024px;
margin-left: auto;
margin-right: auto;
}
.urlInput {
display: block;
width: 100%;
margin-left: auto;
margin-right: auto;
margin-top: 8px;
margin-bottom: 8px;
}
.centeredVideo {
display: block;
width: 100%;
height: 576px;
margin-left: auto;
margin-right: auto;
margin-bottom: auto;
}
.controls {
display: block;
width: 100%;
text-align: left;
margin-left: auto;
margin-right: auto;
}
</style>
</head>
<body>
<div class="mainContainer">
<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()">加載</button>-->
<button onclick="flv_start()">開始</button>
<button onclick="flv_pause()">暫停</button>
<button onclick="flv_destroy()">停止</button>
<input style="width:100px" type="text" name="seekpoint" />
<button onclick="flv_seekto()">跳轉</button>
</div>
<script src="flv.min.js"></script>
<script>
var player = document.getElementById('videoElement');
if (flvjs.isSupported()) {
var flvPlayer = flvjs.createPlayer({
type: 'flv',
url: 'http://192.168.0.100/flv/fkdwc_with_meta.flv'
});
flvPlayer.attachMediaElement(videoElement);
flvPlayer.load(); //加載
}
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>
</body>
</html>
2、在直播的時候，如果使用的是SRS2版本時候，會遇到CORS 頭缺少 'Access-Control-Allow-Origin'問題，通過在SRS上查找問題，發現是SRS2版本上不支持第三方網站的跨域訪問，在SRS3版本上已有修復，w->header()->set("Access-Control-Allow-Origin", "*");，直播的html代碼如下：
flvLive.html
<!DOCTYPE html>
<html>
<head>
<meta content="text/html; charset=utf-8" http-equiv="Content-Type">
<title>flv.js demo</title>
<style>
.mainContainer {
display: block;
width: 1024px;
margin-left: auto;
margin-right: auto;
}
.urlInput {
display: block;
width: 100%;
margin-left: auto;
margin-right: auto;
margin-top: 8px;
margin-bottom: 8px;
}
.centeredVideo {
display: block;
width: 100%;
height: 576px;
margin-left: auto;
margin-right: auto;
margin-bottom: auto;
}
.controls {
display: block;
width: 100%;
text-align: left;
margin-left: auto;
margin-right: auto;
margin-top: 8px;
margin-bottom: 10px;
}
.logcatBox {
border-color: #CCCCCC;
font-size: 11px;
font-family: Menlo, Consolas, monospace;
display: block;
width: 100%;
text-align: left;
margin-left: auto;
margin-right: auto;
}
</style>
</head>
<body>
<div class="mainContainer">
<video name="videoElement" class="centeredVideo" id="videoElement" controls width="1024" height="576" autoplay>
Your browser is too old which doesn't support HTML5 video.
</video>
</div>
<script src="flv.1.5.0.js"></script>
<script>
if (flvjs.isSupported()) {
startVideo()
}
function startVideo(){
var videoElement = document.getElementById('videoElement');
var flvPlayer = flvjs.createPlayer({
type: 'flv',
isLive: true,
hasAudio: true,
hasVideo: true,
enableStashBuffer: true,
url: 'http://10.139.19.55:18080/live/livestreams.flv'
});
flvPlayer.attachMediaElement(videoElement);
flvPlayer.load();
flvPlayer.play();
}
videoElement.addEventListener('click', function(){
alert( '是否支持點播視頻：' + flvjs.getFeatureList().mseFlvPlayback + ' 是否支持httpflv直播流：' + flvjs.getFeatureList().mseLiveFlvPlayback )
})
function destoryVideo(){
flvPlayer.pause();
flvPlayer.unload();
flvPlayer.detachMediaElement();
flvPlayer.destroy();
flvPlayer = null;
}
function reloadVideo(){
destoryVideo()
startVideo()
}
</script>
</body>
</html>
直播效果頁面如下：
3、設備側推流代碼如下：
ffmpeg -re -i fkdwc.flv -vcodec copy -acodec copy -f flv -y rtmp://10.139.19.55/live/livestreams
