sco*_*yab 6 android vimeo video-streaming
我已设法使用以下内容获取加载和播放的vimeo视频.但是,vimeo oembed doc中指示的autoplay = 1 不会在加载时自动播放.任何人都找到了自动播放的方法(也需要在视频播出时捕捉事件)
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setAppCacheEnabled(true);
mWebView.getSettings().setDomStorageEnabled(true);
// how plugin is enabled change in API 8
if (Build.VERSION.SDK_INT < 8) {
mWebView.getSettings().setPluginsEnabled(true);
} else {
mWebView.getSettings().setPluginState(PluginState.ON);
}
mWebView.loadUrl("http://player.vimeo.com/video/24577973?player_id=player&autoplay=1&title=0&byline=0&portrait=0&api=1&maxheight=480&maxwidth=800");

这个答案仅针对Vimeo.经过大约12次失败的尝试,这就是我的工作.也许它会帮助别人.向其他SO答案的原始作者致歉.我已经"借用"了下面的一些模式 - 只是认为将所有这些放在一个地方会很方便,并且不会为我自己的代码声明它们.
首先,我没有找到一种方法来嵌入Vimeo播放器(即你无法直接进入mp4流 - 至少不容易或不可靠 - 我很确定这是故意的).其次,Vimeo提供了一个javascript库来监控他们的播放器,使用它是相当不可避免的.请注意,它需要消息传递,这是一个较新的浏览器功能.这在他们的API页面上有记录.第三,正如SO上其他地方所记载的那样,你需要非常小心地等待堆栈的某些部分准备就绪,并且不要用枪跳.第四,Vimeo播放器包含一个特别无用的背景图像,旨在表明插件丢失或损坏(一小部分电影,常见的图标).真正意味着你的javascript已经被某个地方轰炸了,而且什么都没有运行.如果你在空白屏幕上看到一点点电影,请检查你的javascript.
步骤1.设置WebView.你上面有这个正确的.作为参考,这是我使用的.
mWebView = new WebView((Context) this);
mWebView.setLayoutParams(new LayoutParams(windowWidth, windowHeight));
mWebView.getSettings().setJavaScriptEnabled(true);
// Watch the sdk level here, < 12 requires 'false
// Wanted to force HTML5/264/mp4, you may want flash
// where still available
mWebView.getSettings().setPluginState(PluginState.OFF);
mWebView.getSettings().setLoadWithOverviewMode(true);
mWebView.getSettings().setUseWideViewPort(true);
mWebView.getSettings().setUserAgentString("Android Mozilla/5.0 AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30");
wcc = new MyWebChromeClient();
mWebView.setWebChromeClient(wcc);
wvc = new MyWebViewClient();
mWebView.setWebViewClient(wvc);
步骤2.如果希望视频在WebView上运行,则需要WebChromeClient.这里有记录:http://developer.android.com/reference/android/webkit/WebView.html(请参阅HTML视频支持).
再次,这里是我用的参考.
private class MyWebChromeClient extends WebChromeClient {
@Override
public void onProgressChanged(WebView view, int progress) {
if(progress == 100) {
// Your page is loaded, but not visible,
// add whatever navigation elements you plan to use here.
// N.B. these are JAVA, not JS nav elements
}
}
@Override
public boolean onConsoleMessage(ConsoleMessage cm) {
// I like to watch in the console. And, since it was
// a very convenient way to monitor the javascript, I
// use it for that too. Purists will object, no doubt
if(cm.message().equalsIgnoreCase("EVENT -- Finish")) {
Log.i(TAG, "---> Finishing . . .");
// Depart the activity
finish();
} else {
Log.d(TAG, " **Console ["+cm.sourceId()+"] ("+cm.lineNumber()+") ["+cm.message()+"]");
}
return(true);
}
@Override
public View getVideoLoadingProgressView() {
// Something entertaining while the bytes arrive
Log.i(TAG, " -------------> Loading Progress . . . ");
LayoutInflater inflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
return(inflater.inflate(R.layout.loading_video, null));
}
@Override
public void onShowCustomView(View v, WebChromeClient.CustomViewCallback callback) {
// With great sadness, I report that this never fires.
// Neither does the 'hide'.
}
@Override
public void onHideCustomView() {
}
}
WebViewClient看起来像这样:
private class MyWebViewClient extends WebViewClient {
@Override
public void onPageFinished(WebView view, String url) {
super.onPageFinished(view, url);
String injection = injectPageMonitor();
if(injection != null) {
Log.d(TAG, " ---------------> Page Loaded . . .");
Log.d(TAG, " Injecting . . . ["+injection+"]");
view.loadUrl(injection);
}
}
}
第3步.您需要构建一小部分Javascript来激活播放器.我用过这个:
public String injectPageMonitor() {
return( "javascript:" +
"jQuery(document).ready( function() { " +
"console.log(' === Page Ready ===> Setting up');" +
"console.log(' ==== Sending PLAY Command ===');" +
"var froogaloop = $f('froog');" +
"setTimeout(function() { froogaloop.api('play'); }, 3000);" +
"});");
}
快速解释...我在我的JS中使用jQuery,这将在下面.这只是为了方便,如果你想减轻负担,你可以直接做JS.请注意,在其他所有内容准备就绪后,脚本会等待另外3秒钟才能实际触发.在我较弱的时刻,我想Vimeo的善良人士有一个破碎的"准备好"的回调.3秒似乎是这样做的.
第4步.您需要在页面上使用一些HTML和JavaScript.我把它放在资源里面的一个文本文件中(raw/vimeo_frame.html).该文件如下所示:
<!DOCTYPE html>
<html>
<head>
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"></script>
<script type="text/javascript">jQuery.noConflict();</script>
<script src="http://a.vimeocdn.com/js/froogaloop2.min.js"></script>
<script type="text/javascript">
jQuery(document).ready( function() {
var showing_player = false;
var froogaloop = $f('froog');
console.log(' === Page Ready ===> Setting up');
jQuery('.froog_container_class').hide();
jQuery('.console').css('height', '100%');
froogaloop.addEvent('ready', function() {
console.log('==== PLAYER READY ====> Setting Play Callback');
froogaloop.addEvent('play', function(data) {
console.log('EVENT -- Play');
/* No idea why, but if the player isn't displayed, it goes
straight to 'pause'. Probably a feature. So I give it 4x4px
to do it's thing during setup */
jQuery('.froog_container_class').show();
jQuery('.froog_container_class').css('height', '4px');
jQuery('.froog_container_class').css('width', '4px');
jQuery('.froog_container_class').css('overflow', 'hidden');
});
/* I don't want to reveal the video until it is actually
playing. So I do that here */
var showingPlayer = false;
froogaloop.addEvent('playProgress', function(data) {
if(!showingPlayer && data.percent > 0) {
showingPlayer = true;
jQuery('.froog_container_class').show();
jQuery('.froog_container_class').css('height', '_windowHeight');
jQuery('.froog_container_class').css('width', '_windowWidth');
/* Most tablets I tested aren't quick enough to make this work
but one can still hope */
jQuery('#loading').fadeOut('slow');
}
});
});
});
</script>
</head>
<body>
<style>
body {
background-image: url('http://<SomethingEntertainingToWatch>.png');
background-size: contain;
}
.mask {
float: left;
height: _windowHeight;
width: _windowWidth;
z-index: 100;
background: transparent;
display: inline;
position: absolute;
top: 0;
left: 0;
}
.froog_container_class {
position: absolute;
height: _windowHeight;
width: _windowWidth;
left: 0;
top: 0;
display: inline;
z-index: 1;
}
#froog {
display: inline;
height: _windowHeight;
width: _windowWidth;
postion: absolute;
top: 0;
left: 0;
}
</style>
<div id="loading" class="loading"><h1>Loading</h1><img class="loading_anim" src="http://foo.bar.com/assets/global/loading.gif"/>
</div>
<!-- Completely optional, I put a div in front of the player to block controls -->
<div id="mask" class="mask">
</div>
<div id="froog_container" class="froog_container_class">
<iframe id="froog" src="_targetUrl?api=1&title=0&byline=0&portrait=0&player_id=froog" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen>
</iframe>
</div>
</body>
</html>
我像这样加载这个html文件:
public String genMainHTML() {
String code = null;
try {
Resources res = getResources();
InputStream in_s = res.openRawResource(R.raw.vimeo_frame);
byte[] b = new byte[in_s.available()];
in_s.read(b);
code = new String(b);
} catch (Exception e) {
e.printStackTrace();
}
if(code != null) {
code = code.replaceAll("_windowHeight", "" + windowHeight + "px");
code = code.replaceAll("_windowWidth", "" + windowWidth + "px");
code = code.replaceAll("_targetUrl", targetUrl);
return(code);
} else {
return(null);
}
}
并注入它:
mDomain = "http://player.vimeo.com";
mWebView.requestFocus(View.FOCUS_DOWN);
targetUrl = extras.getString("URL");
String meat = genMainHTML();
mWebView.loadDataWithBaseURL(mDomain, meat, "text/html", "utf-8", null);
setContentView(mWebView);
呼!当WebView准备就绪时,html和js会进入,包括带有Vimeo播放器的iframe.加载文档后,我们等待播放器准备就绪.当播放器准备就绪时,我们会添加一些听众.3秒后,我们开始了api'play'方法.
观众中的那些苹果抛光者可能想知道,为了完整起见,如何停止视频？两位.首先,当它结束时,我通过观察控制台输出来显示我显示的消息来停止它.从而:
public String injectPageFinisher() {
return( "javascript:" +
"jQuery(document).ready( function() { " +
"console.log(' === Page Ready ===> Tearing down');" +
"console.log(' ==== Sending PAUSE Command ===');" +
"var froogaloop = $f('froog');" +
"froogaloop.api('pause');" +
"jQuery('#froog_container').html('');" +
"});");
}
哪个可以像这样插入:
@Override
public void onPause() {
super.onPause();
if(isFinishing()){
// Unload the page
if(mWebView != null) {
Log.i(TAG, " ------> Destroying WebView");
mWebView.destroy();
}
}
finish();
}
第二位是视频完成其自我的小地方.因此,在上面的vimeo_frame.html中,就在'play'回调之后,我把:
froogaloop.addEvent('finish', function(data) {
console.log('EVENT -- Finish');
});
在Activity中,我稍微注意了一下 - 参见上面的onConsoleMessage覆盖.
但是 - 在撰写本文时,我仍然没有排除一个棘手的问题.在WebView及其所有后代都消失之后,MediaPlayer继续存在.我确定这会产生一些问题,但我还没有发现它们.
我们遇到了同样的问题,似乎Android WebView(以及iOS上的那些)没有编程允许自动启动视频,因为它可能会影响某人的数据计划.你必须真正点击它,除非你想把谷歌WebView作为一个起点并自己动手.它并不像听起来那么容易,我们试过了!
