It is not a shortcode. I am using wordpress theme TrueMag and the player is one of several integrated into the theme. In Firefox here is the page source:

<input type=”hidden” name=”main_video_url” value=”http://mysite.com/wp-content/uploads/2015/12/myclip.webm
http://mysite.com/wp-content/uploads/2015/12/myclip.m4v
http://mysite.com/wp-content/uploads/2015/12/myclip.ogv”/&gt;
<input type=”hidden” name=”main_video_type” value=”self-hosted”/>
<div class=”single-inbox”>
<div id=”player”>
<div class=”video-player”>
<div class=”player-content”>
<div class=”player-content-inner”>
<div id=”player-embed”>
<div id=”wpfp_45d4bbc62a1e855e23d629b771d6813c” class=”flowplayer no-brand is-splash play-button” style=”max-width: 720px; max-height: 480px; ” data-ratio=”0.6667″>
<video poster=”http://mysite.com/wp-content/uploads/2015/12/myclip.m4v.jpg&#8221; preload=”none”>
<source src=”http://mysite.com/wp-content/uploads/2015/12/myclip.webm&#8221; type=”video/webm”/>
<source src=”http://mysite.com/wp-content/uploads/2015/12/myclip.m4v&#8221; type=”video/mp4″/>
<source src=”http://mysite.com/wp-content/uploads/2015/12/myclip.ogv&#8221; type=”video/ogg”/>
</video>

Now with this source in Firefox the m4v is what plays instead of the webm which is what should be playing. The reason i suspect it is flash is that it will not seek past the buffer line and with other players if m4v is the source it will seek fine(because it is playing the m4v in html5 not flash.)

Hi

I need to know how to disable flash fallback.

There is no need for it in my situation and it is causing troubles. I scanned this thread and cannot find that this has been answered. Please just tell me how to disable it.

Thanks,
Steve
