Hi, I have posted it on http://dev.live.com/silverlight/downloads/SL_v1_player_sample.zip. The v10 folder contains a regular SL v1 player (xaml and js) from Expression Encoder. The files relevant to this thread are: WebPageSample.htm and JavaScriptSample.js.
In WebPageSample.htm the parts that matter are the following:
<script type="text/javascript" src="JavaScriptSample.js"></script> this is where you reference the script
var p = new StartPlayer(); this is where you create the instance of your player on your site.
In JavaScriptSample.js, the parts that matter are the following:
initParams: ["streaming:/SLS_account_ID/File_set/File_Name.wmv"] this is where you pass the "URL" to your video file
this._player.set_mediaUrl (params[0]); this is where you set the value of mediaUrl to be the translated http URL
Hope this helps.
