if you want to embed a video in your website and you want to play it automatically, you can do it by modifying the url in the code

for example i have this:

<object width="512" height="322"><param name="movie" value="http://d.yimg.com/static.video.yahoo.com/yep/YV_YEP.swf?ver=2.2.30" /><param name="allowFullScreen" value="true" /><param name="AllowScriptAccess" VALUE="always" /><param name="bgcolor" value="#000000" /><param name="flashVars" value="id=v45981361&vid=2339376&lang=en-us&intl=us&thumbUrl=http%3A//d.yimg.com/img.music.yahoo.com/image/v1/video/45981361%3Bsize%3D300x180&embed=1" /><embed src="http://d.yimg.com/static.video.yahoo.com/yep/YV_YEP.swf?ver=2.2.30" type="application/x-shockwave-flash" width="512" height="322" allowFullScreen="true" AllowScriptAccess="always" bgcolor="#000000" flashVars="id=v45981361&vid=2339376&lang=en-us&intl=us&thumbUrl=http%3A//d.yimg.com/img.music.yahoo.com/image/v1/video/45981361%3Bsize%3D300x180&embed=1" ></embed></object>

i just add &autoplay=1 to the url and it would look like this:


<object width="512" height="322"><param name="movie" value="http://d.yimg.com/static.video.yahoo.com/yep/YV_YEP.swf?ver=2.2.30" /><param name="allowFullScreen" value="true" /><param name="AllowScriptAccess" VALUE="always" /><param name="bgcolor" value="#000000" /><param name="flashVars" value="id=v45981361&vid=2339376&lang=en-us&intl=us&thumbUrl=http%3A//d.yimg.com/img.music.yahoo.com/image/v1/video/45981361%3Bsize%3D300x180&embed=1&autoplay=1" /><embed src="http://d.yimg.com/static.video.yahoo.com/yep/YV_YEP.swf?ver=2.2.30" type="application/x-shockwave-flash" width="512" height="322" allowFullScreen="true" AllowScriptAccess="always" bgcolor="#000000" flashVars="id=v45981361&vid=2339376&lang=en-us&intl=us&thumbUrl=http%3A//d.yimg.com/img.music.yahoo.com/image/v1/video/45981361%3Bsize%3D300x180&embed=1&autoplay=1" ></embed></object>


NOTE: be sure to add the &autoplay=1 on both urls. see the code above where its underline it shows you were i put the autoplay part
