If by "player" you mean browser, then embed your flash file with this code. Published right from flash so it will work.
This was published in Flash 8...if you want it to be published in a lower version, just go File -> Publish Settings. Select the Flash tab and Version is at the top, just select which version you wish to publish the swf as. Also make sure HTML is checked in the Formats tab, this will just publish an html file with it, then you can just copy all the code between the <object></object> tags (including the object tags) and put that in your html document.
