html5 mp4的app,video - Playing local/in-app mp4 files in a HTML5 videoplayer in a Cordova PhoneGap ap...

I got the video to work on Android 4.0.3 (API 15) and up using Jaeger 25's Html5Video plugin. However, With the addition of Android 4.4 and its revised Chromium-based WebView, this plugin no longer suffices, as mentioned by its awesome developer.

Now, I would much rather play these video's without any plugins anyway (which works perfectly on iOS...), so I went back to trying that. Is was hoping that this Chromium-based webview would be friendlier with basic HTML5 playback, but instead, I just get the exact same error as before: MediaPlayer(30579): Error (1,-2147483648).

I've spent hours trying several different approaches, all to no avail. I'll list a few things that I've tried below. Please, does anyone have any clues to point me in the right direction? I'm out of ideas...

Normal file reference using file:///
