This extension helps you display a list of video files, with navigation by cue points. It was originally created for lectures.

See also FLVPlayer.

Syntax

The Flash Video extension use the <flv></flv> tag to add a List of Video-Files that should be displayed in the Wiki. The flv-Files are external files. If the Video Files contain Cue Points, those are displayed and offered for navigation.

Sample

The flv-Tag takes several attributes and contains one line for each flv-file:

<flv 
   title="Beispiel mit xxx und yyy" 
   base="http://some.where.on.the.net/folder/with/files/">
 first.flv|First things first
 second.flv|Second to none
 third.flv|Third time's a charm
</flv>

• Use the base attribute if all your flv-files are contained in one folder
• the title attribute will be displayed bottom left on the player
• each line inside the flv-tag consists of:
  • the URL or filename of the flv-files
  • |
  • the title of the movie (will be displayed top left in the player)

Installation

You need to drop three files into your extensions-folder,

1. flv.php - code given below
2. wiki-video-player.swf - the Player itself
3. SteelExternalAll.swf - a part of the FLVPlayback-Component from Actionscript 2

LocalSettings.php

Place

require_once("extensions/flv.php");

inside LocalSettings.php.

flv.php

When you copy the following code: Remove any whitespace before the EOM; on line 84. The E really needs to be the first character on this line.
