## @param width:title=Width|type=string|required=false|desc=Video width

## Tested on Google Chrome and Safari using mp4 files
## Does not work for mp4s on Firefox as Mozilla does not support mp4 files - lame
## Fail-back to Flash/Flow Player for old browsers -- Tested on Internet Explorer 8
##
## Usage: {html5video:src=myvideo.mp4|width=600|height=400}

#set ($attachment = $content.getAttachmentNamed($paramsrc)) 

<video controls="controls" 
	#if ($paramwidth)  width="$paramwidth"   #end
	#if ($paramheight) height="$paramheight" #end
	#if ($paramposter) poster="$paramposter" #end ## Set a placeholder image for the video
	>
	<source type="video/$attachment.getFileExtension()" src="$attachment.getDownloadPath()" />
	<object type="application/x-shockwave-flash" data="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf"
		#if ($paramwidth)  width="$paramwidth"   #else width="640"  #end
		#if ($paramheight) height="$paramheight" #else height="360" #end
		>
		<param name="movie" value="http://releases.flowplayer.org/swf/flowplayer-3.2.1.swf" />
		<param name="allowFullScreen" value="true" />
		<param name="wmode" value="transparent" />
		<param name="flashVars" value="config={'playlist':[{'url':'$generalUtil.urlEncode("$action.getGlobalSettings().getBaseUrl()${attachment.getDownloadPath()}")','autoPlay':false}]}" />
		<span title="No video playback capabilities, please download the video below"></span>
	</object>
</video>
<p>
	<strong>Download video:</strong> <a href="$attachment.getDownloadPath()">$attachment.getFileExtension() format</a>
</p>

<script>
	## Remove the Firefox lameness and revert to the Flow Player embed
	if (jQuery.browser.mozilla) jQuery('source[type="video/mp4"]').unwrap();
</script>

The HTML5 Video macro does not properly sanitize the 'width' and 'height' parameters so that arbitrary JavaScript can be injected into the site.
