Download the FLV Player.
Put the flvplayer.swf file on your site. For example, mine lives at
http://granades.com/flv/flvplayer.swf.
Upload your FLV file to your site.
To embed the FLV file in an HTML page or blog post, add the following HTML:
<object type="application/x-shockwave-flash" width="[width]" height="[height+20]" wmode="transparent"
data="/flv/flvplayer.swf?file=[movie]&autostart=false">
<param name="movie" value="/flv/flvplayer.swf?file=[movie]&autostart=false" />
<param name="wmode" value="transparent" />
</object>
/flv/flvplayer.swf is the relative URL to the flvplayer.swf file. [width] is the width of your FLV file (which I normally make to be 320) and [height+20] is the height of your FLV file plus 20 pixels. [movie] is where you uploaded your FLV file. &autostart=false means the visitor will have to click on the video before it plays — it’s optional, and may be left out if you want the video to play when the page is loaded.
