问题
尝试从webview(android 5.0)中播放视频会导致许多" Cross origin请求"失败和视频不播放。 但是,在谷歌浏览器上,在笔记本电脑上,下面的HTML使视频播放完美无缺!
HTML
<!DOCTYPE html>
<html>
<head>
<style>
html{width:100%;height:100%;}
body{margin:0;width:100%;height:100%;background-color:black;}
</style>
</head>
<body>
<div id='player'></div>
<script>
var playerLoaded = false;
var percentReported = 0;
var percentCurrent = 0;
var tag = document.createElement('script');
tag.src = 'http://www.youtube.com/player_api';
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubePlayerAPIReady() {
playerLoaded = true;
player = new YT.Player('player', {
width:'100%',
height:'100%',
videoId:'CpaOh4poNms',
playerVars: { playsinline: 1 },
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange,
'onError': onPlayerError
}
});
}
function onPlayerReady(event) {
event.target.playVideo();
setInterval(onPlayerTimeUpdate, 1000);
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED) {
}
}
function onPlayerError(event) {
}
function onPlayerTimeUpdate() {
percentCurrent = Math.round(player.getCurrentTime() / player.getDuration() * 100);
if (percentCurrent > percentReported) {
percentReported = percentCurrent;
}
}
setTimeout(function() {
if (!playerLoaded) {
}
}, 10000);
</script>

我错过了什么?
PROGRESS ...
我可以在Android&#39;(5.0)webview上使用此垃圾的唯一方法是使用以下HTML ...
<html>
<body>
<iframe width="100%" height="100%" src="http://www.youtube.com/embed/CpaOh4poNms?rel=0&autoplay=1" frameborder="0" allowfullscreen></iframe>
</body>
</html>
至少会显示视频播放器。这整个动态div-to-iframe垃圾在Android上完全不起作用:https://developers.google.com/youtube/iframe_api_reference#Getting_Started
答案 0 :(得分:0)
我已经知道在Android上调用了onYouTubeIframeAPIReady()
和onYouTubePlayerAPIReady()
从不。
我想知道这是否有意迫使人们切换到YouTube Library - 如果图书馆不依赖于YouTube应用,我会这样做。 我认为应该有一个&#34;脂肪&#34;和&#34;瘦&#34;图书馆的版本;瘦版本取决于youtube应用程序,胖版本可选择它。
要制作视频自动播放,请使用以下代码:
https://stackoverflow.com/a/27722504/550471
并从onPageFinished()
要将HTML加载到WebView中,我使用:
webView.loadDataWithBaseURL("http://www.youtube.com", youtubeHTML, "text/html; charset=utf-8", "UTF-8", null);
HTML包含:
<html>
<head></head>
<body>
<iframe id="player" width="100%" height="100%" src="http://www.youtube.com/embed/CpaOh4poNms?rel=0&origin=youtube.com" frameborder="0" allowfullscreen></iframe>
</body>
