【问题描述】：
我是移动应用程序开发的新手，我正在尝试在 html5 的帮助下使用 cordova/phonegap 制作视频播放器。经过大量搜索，我意识到没有原生android播放视频是不可能的。请在这方面帮助我，我希望我的应用程序从移动存储和 SD 卡中获取所有视频文件并列出所有这些文件。单击自定义视频播放器后开始播放。
我首先尝试了这个插件
https://github.com/amuelli/Html5Video
但没有成功。
然后，我尝试了其他可用的视频插件，但仍然没有成功。我在这里粘贴的代码给出了一个丑陋的输出，但这就是我已经达到的，这段代码没有任何插件。

【问题讨论】：
-
你确定你已经测试了官方的cordova媒体插件吗？ github.com/apache/cordova-plugin-media
-
不，我没试过。
-
Sithys，该插件提供了在设备上录制和播放音频文件的能力。对视频文件有帮助吗？
-
对那个 Manu 感到抱歉，这是正确的。科尔多瓦视频播放器怎么样？ github.com/moust/cordova-plugin-videoplayer
-
Sithys 你在帮我。请不要抱歉。而且恐怕这个特定的插件不支持文件获取。
