[Plugin: Viper’s Video Quicktags] suggestion to shortcode_videofile() function

Video tag ([video][/video]) doesn’t play in Firefox.

But if you add <embed /> between <object></object> then its ok

<embed type="application/x-mplayer2" pluginspage="https://www.microsoft.com/isapi/redir.dll?prd=windows&sbp=mediaplayer&ar=Media&sba=Plugin" filename="' . $content . '" src="' . $content . '" showPositionControls="1" showAudioControls="1"  showStatusBar="1" width="' . $atts['width'] . '" height="' . $atts['height'] . '" autoStart="0" />

all together will be

return '<span class="vvqbox vvqvideo" style="width:' . $atts['width'] . 'px;height:' . $atts['height'] . 'px;"><object classid="CLSID:6BF52A52-394A-11d3-B153-00C04F79FAA6" codebase="https://activex.microsoft.com/activex/controls/mplayer/en/nsmp2inf.cab#Version=5,1,52,701" standby="Loading Microsoft Windows Media Player components..." type="application/x-oleobject" width="' . $atts['width'] .
