Flash embedded in HTML doesn't appear in Chrome

i know is an old post , but i ran to this problem too and i found a solution, when you embed a video in worpress, use just the "embed" tag, because it seems that google chrome when its read the "object" tag, skips the tags inside ,

OLD CODE

<object classid="clsid:d27cdb6e-ae6d-11cf-96b8-444553540000"   codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=6,0,40,0" width="600" height="1300"><param name="src" value="flash.swf" /><param name="wmode" value="transparent" /><embed type="application/x-shockwave-flash" width="600px" height="1300px" src="flash.swf" wmode="transparent"></embed></object>

NEW CODE

<embed type="application/x-shockwave-flash" width="600px" height="1300px" src="flash.swf" wmode="transparent"></embed>

Also as suggested by @joshuahedlund and probably the right answer , just adding the type seems to fix the issue

<object type="application/x-shockwave-flash" ... > ... </object>

I've used this javascript code snippet for a while and it seems to work find in most browsers. You'll need the AC_RunActiveContent.js for this, download it from http://www.adobe.com/devnet/activecontent/articles/devletter.html

<script type="text/javascript">AC_FL_RunContent('id', 'mediaPlayer','codebase', 'http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=9,0,0,0','width', '480','height', '360','src', 'myFlashMovie.swf','quality', 'high','pluginspage', 'http://www.macromedia.com/go/getflashplayer','align', 'middle','play', 'true','loop', 'true','scale', 'showall','wmode', 'window','devicefont', 'false','bgcolor', '#000000','name', 'mediaPlayer','menu', 'true','allowFullScreen', 'true','allowScriptAccess', 'sameDomain','movie', 'myFlashMovie.swf','salign', '');</script>

Why don't you try proper

width="600" height="1300" 

instead of

width="600px" height="1300px" 

(which is not in HTML standard)?
