Video 在Android 4.4及更低版本上的Cordova PhoneGap应用程序中的HTML5视频播放器中播放本地/应用内mp4文件

我使用Android 4.0.3（API 15）和更高版本制作了视频。然而，随着安卓4.4及其基于Chromium的修订版WebView的加入，这个插件不再满足需要

现在，我更愿意在没有任何插件的情况下播放这些视频（它在iOS上运行得非常好…），所以我回去尝试了。Is希望这个基于Chromium的网络视图能够更友好地播放基本的HTML5，但我得到的错误与以前完全相同：

MediaPlayer（30579）：错误（1，-2147483648）

我花了几个小时尝试了几种不同的方法，但都没有用。下面我将列出一些我尝试过的东西。请问，有没有人能给我指出正确的方向？我没有主意了

使用文件的正常文件引用：//

代码：

使用Phonegap的文件系统API的文件引用

代码：

    <video id="whoismad" width="75%" height="75%" loop class="videoplayer">
        <source src="cdvfile://android_asset/www/res/raw/whoismad.mp4" type="video/mp4">
    </video>

在尝试从应用程序资产中读取视频文件时，Cordova 3.4目前似乎不可能做到这一点

看

如果文件被复制到应用程序资产之外的目录，或者文件被远程存储，则可以读取该文件。但不再在app assets文件夹中

我有一个类似的问题-我的应用程序有一个欢迎屏幕，屏幕上有一个简短的视频，解释应用程序（~300k），我不能在APK之外播放。

非常感谢您排除了这一点。链接已经消失了，所以很明显我已经看到了这一个，但只是过去了。。。我简直不敢相信这么（看似）琐碎的事情是办不到的。总结：“APK类似于JAR文件，它是一种特殊类型的ZIP文件，其中包含应用程序的类及其资源和资产。对于要从资产访问的任何文件，必须对其进行解压缩。这对于不是视频的文件来说是微不足道的，但显然由于视频文件的性质，Android无法解压缩这些文件并播放它们。”
