直播推流地址和播放地址本身沒有API接口,需要在客戶端自行拼接地址,然后使用推流工具或者播放器對其推流或播放。本文介紹如何通過PHP、Java代碼生成直播的推流以及播放地址。
PHP代碼示例
視頻直播生成推流地址和播放地址的PHP示例代碼如下所示。
<?php
/**
* 生成推流地址
* @param $push_domain 推流域名
* @param $push_key 推流域名配置的鑒權Key
* @param $expireTime 過期時間(單位是秒)
* @param $appName 推流AppName
* @param $streamName 推流StreamName
*/
function push_url($push_domain,$push_key,$expireTime,$appName,$streamName){
$push_url = '';
//未開啟鑒權Key的情況下
if($push_key==''){
$push_url = 'rtmp://'.$push_domain.'/'.$appName.'/'.$streamName;
echo $push_url;
return;
}
$timeStamp = time() + $expireTime;
$sstring = '/'.$appName.'/'.$streamName.'-'.$timeStamp.'-0-0-'.$push_key;
$md5hash = md5($sstring);
$push_url = 'rtmp://'.$push_domain.'/'.$appName.'/'.$streamName.'?auth_key='.$timeStamp.'-0-0-'.$md5hash;
echo $push_url;
echo PHP_EOL;
return;
}
/**
* 生成播放地址
* @param $play_domain 播放域名
* @param $play_key 播放鑒權Key
* @param $expireTime 過期時間(單位是秒)
* @param $appName 播放appName(同推流appName)
* @param $streamName 播放streamName,播放源流時,streamName 同推流streamName;播放轉碼流時,streamName 為推流streamName_{轉碼模板ID}
*/
function play_url($play_domain,$play_key,$expireTime,$appName,$streamName){
//未開啟鑒權Key的情況下
if($play_key==''){
$rtmp_play_url = 'rtmp://'.$play_domain.'/'.$appName.'/'.$streamName;
$flv_play_url = 'http://'.$play_domain.'/'.$appName.'/'.$streamName.'.flv';

echo PHP_EOL;
return;
}
//推流域名
$push_domain = 'testpush.cn';
//推流域名配置的鑒權Key
$push_key = 'test_Push_key';
//生成隨機的AppName
$appName = md5(uniqid(microtime(true),true));
//生成隨機的StreamName
$streamName = md5(uniqid(microtime(true),true));
//配置過期時間為1小時
$expireTime = 3600;

}
try {
MessageDigest md5 = MessageDigest.getInstance("MD5");
md5.update(param.getBytes());
byte[] byteArray = md5.digest();
BigInteger bigInt = new BigInteger(1, byteArray);
// 參數16表示16進制
String result = bigInt.toString(16);
// 不足32位高位補零
while(result.length() < 32) {
result = "0" + result;
}
return result;
} catch (NoSuchAlgorithmException e) {
e.printStackTrace();
}
return null;
}
