I have installed Flash Video Player Wordpress Plugin and successfully embeded a playlist as instructed with the following tag:
[flashvideo filename=wp-content/uploads/2008/11/playlist_three.xml /]
I cannot find ANYWHERE on the net, how to interact with the player with Javascript etc from within wordpress.
My aim is to have a player with a combobox picker that the user can choose a playlist, same as this example in the link below (But I want to do this inside a page/post in Wordpress):
http://home5.inet.tele.dk/nyboe/flash/mediaplayer/multipleplaylists.htm
Someone please tell me how to interact with the player from within a wordpress post, do I use HTML tab inside the post or do I have to modify something else like a .php file.
Surely someone out there has interacted with the player in wordpress before !
HELP

I didn't find any decent explanation on this either. The code from the examples of Jeroen's site simply doesn't work in WordPresss. Since i urgently have to get this working on my own site, I use a workaround:
First of all, I'm used to work with the Flash video player plugin from http://www.mac-dev.net/blog/download-flash-video-player-plugin-for-wordpress/
It makes use of Jeroen's player, so that comes close to what we want. However, regarding playlists, mac-dev throws the hot potato back to Jeroen's site because he probably doesn't know what to do with it and this is not abnormal because WordPress and Flashvars are not the best of friends.
Now, a solution: It is a bit cumbersome, but for the time being, it is useful:
In the WP plugin, there is a parameter for recommendations. So if you create an xml file which you call "recommendations.xml" or whatever, and you fill in something similar like:
<recommendations>
<recommendation>
<title>Joomla! Home</title>
<image>http://www.miracletutorials.com/images/logoMT.gif</image>
<link>http://www.joomla.org</link>

</recommendations>
And then you create a new post in which you write (and it doesn't matter if you use the html or wysiwyg mode):
[flashvideo filename=http://www.yourdomain.com/folder/whatever.flv width=480 height=360 image=http://www.yourdomain.com.com/images/posterimage.jpg recommendations=http://www.yourdomain.com/myplaylist/recommendations.xml /]
Then you will have a video that plays and at the end it will show you a group of icons in the player from which you can send people to other videos or rather other posts which contain video. Now, I agree, this is not the ideal and I do hope someone finds a way to get playlists working, but at least it is a start :-)
Hope this helps!
