Android webview html5 视频自动播放在 android 4.0.3 上不起作用 [英] Android webview html5 video autoplay not working on android 4.0.3

问题描述

我开发了一个应用程序，用户可以在其中设置网页上的视频:- 他们可以指定一个 Youtube URL或者- 他们可以上传视频

I have developed an application where the user can set videos on a web page: - They can specify a Youtube URL OR - They can upload a video

根据用户选择的选项，我呈现这样的视频页面:如果视频来自 youtube:

Depending on which option the user chooses i render a video page like this : If a video is from youtube:

<iframe type="text/html" width="640" height="385" src="http://www.youtube.com/embed/YOUTUBEID?autoplay=1&loop=1&autohide=1&fs=0"  frameborder="0"></iframe>

如果视频正在上传:

<video id="video" style="cursor: pointer;" width="640" height="480"  autoplay controls loop>
  <source src="../video/Tareas_Diarias_Resumen.mp4" type="video/mp4" />
</video>

好的.所有这些都可以在 Google Chrome 上完美运行，但事实是该视频将在 16 台三星 GT-P5100 Android 4.03 平板电脑上观看.

OK. All this works perfect on Google Chrome, but the fact is that the video is going to be watched on 16 Samsung GT-P5100 Android 4.03 Tablets.

我们创建了一个嵌入 webView 的 Android 应用程序:

We created an Android application which embeds an webView like that:

WebView engine = (WebView) findViewById(R.id.web_engine);
engine.setWebChromeClient(new WebChromeClient());
engine.getSettings().setPluginsEnabled(true);
engine.getSettings().setPluginState(PluginState.ON);
engine.getSettings().setJavaScriptEnabled(true);
engine.getSettings().setAllowFileAccess(true);
engine.loadUrl(miUrl);

这里我有两个问题:1-Youtube 视频.它工作正常，我可以看到视频但没有自动播放，我们希望它可以自动播放.有什么解决办法吗?2- 上传的视频不起作用，我可以看到播放器但没有视频.

And here I have two issues: 1- Youtube video. It works ok, I can see the video but with no autoplay, and we want it to work with autoplay. Any solution? 2- The uploaded video does not work, I can see the player but no video.

视频转手刹，选择iphone &ipod-touch 预设和网页优化"选项.

The video was converted with handbrake, choosing iphone & ipod-touch preset and "Web Optimized" option.

任何帮助或线索?提前致谢

Any help or clue? Thanks in advance

大多数移动平台(Android、iOS)上的自动播放被阻止以避免糟糕的用户体验 - 视频应仅在用户操作后播放.您通常可以通过在另一个事件(例如 onloaded 事件)上触发 play() 来解决它

Autoplay on most mobile platforms (Android, iOS) gets blocked to avoid poor user experiences - video should only play following a user action. You can usually work around it by triggering the play() on another event (eg the onloaded event)
