Hello All,

I have an issue in Sharepoint 2013 related to youtube embed iframe links that i copy and paste from youtube embed video link and place it in my video library (Please see this : SPVideo image 1).

It gets uploaded successfully and get played successfully from the "Site Contents" where the video has been uploaded.

But when i use that video in an xsl Webpart it shows "Media Failed to Load", below is xsl code :

<div class="col-lg-4 col-md-4 col-xs-6 thumb">   	
  	    <a class="thumbnail" href="#" data-toggle="modal" data-target=".bs-example-modal-lg">   		
			<img src="{@ImageUrl}" data-desc="{substring(@Description,0,300)}" data-Video="{@LinkUrl}"  önclick="openInDialog('{@Title}',800,800,false,true,false,'/Pages/MediaWebPart.aspx?{@LinkUrl}.wmv')" ></img>
		</a> 					
		<span>
			<xsl:value-of select="substring(@Title,0,100)"></xsl:value-of>
		</span> 
    </div>     

Here are the image links of dropbox where you can refer to my steps to problem that i am facing :

1. Pasting Youtube embed code in video gallery: SPVideo image 1
2. After saving it comes to Videopage (which plays video) : SPVideo image 2
3. XSL Webpart list page where all videos are listed in image video(from above xsl code) : SPVideo image 3
4. A popup which opens a Dialog (from above xsl code) : SPVideo image 4

I have been trying to search this issue but unable to resolve this from 2 days.
Please help if you have any solution. Any help would be appreciated.
