The image gallery displays videos with following markup:
<embed wmode="opaque" autoplay="true" showcontrols="true" showstatusbar="true" showtracker="true" src="http://www.amateurpyro.com/forums/uploads/gallery/something.mp4" type="video/mp4" width="640" height="480"></embed>
It does not work. Only thing to make it work is to change the "embed" to "video".
<video wmode="opaque" autoplay="true" showcontrols="true" showstatusbar="true" showtracker="true" src="http://www.amateurpyro.com/forums/uploads/gallery/something.mp4" type="video/mp4" width="640" height="480"></embed>
Or better yet (the embed is for compatibility):
<video autoplay="autoplay" controls="controls" width="640" height="480"> <source type="video/mp4" src="http://www.amateurpyro.com/forums/uploads/gallery/something.mp4"/> <embed wmode="opaque" autoplay="true" showcontrols="true" showstatusbar="true" showtracker="true" src="http://www.amateurpyro.com/forums/uploads/gallery/something.mp4" type="video/mp4" width="640" height="480"></embed> </video>
If the you are afraid of HTML5 elements, why using HTML5 DTD header?
Video element description on W3Schools
Or just include link to the actual video file. Not everyone is skilled to view source or open document inspector.
