I installed this on a wordpress blog and it was a no-go. Just a black box or a grey box with an x in it. Sometimes the controls would show up, sometimes not.Video and audio plugin for WordPress built on the MediaElement.js HTML5 media player library. Provides Flash or Silverlight fallback players for non-HTML5 browsers. Supports iPhone, iPad, and Andriod. Supports MP4, OGG, WebM, WMV, MP3, WAV, WMA files as well as captions with WebSRT files.
Worked fine in Chrome.
