When searching for a possibility to embed Flash videos (FLV) in DokuWiki pages, i found http://www.dokuwiki.org/plugin:flashplayer. With this plugin it is possible, to embed Flash videos using the command <flashplayer>.
However, this plugin has a problem: It generates an EMBED element in the HTML output, which is not conform to XHTML. Visitors do also not see, why a video is not played, in case neither Flash is installed nor JavaScript is activated.
A better approach ist using OBJECT elements, which comply to the standard.
Finally i extended the plugin by Sam Hall according to these requirements. It is suitable for DokuWiki 2008-05-05 or later and was tested with Internet Explorer 6, 7 and 8, Firefox 3.5 (Windows and Linux) and Webkit (Safari, Chrome)
Wenn you put video files as media in DokuWiki, you can not access the directly, but only via DokuWiki. You can use two variants for the "file" parameter:
If the file .htaccess is not used: /lib/exe/fetch.php?media=Filename.flv
With active .htaccess file: /_media/Filename.flv
Maybe the path has be to extended, if the Wiki installation is not in the root directory - e.g. /wiki/lib/exe/fetch.php?media=Filename.flv, if the Wiki is accessed using http://servername/wiki/.
