Introduction

Streaming media in OpenSimulator works the same way as in SL. One of the most frequent misconceptions about streaming content in OpenSimulator is the simulator or regions server is actually doing the streaming. This is not true, all streaming happens outside of the metaverse on a seperate dedicated server. The streaming content is fed directly to Quicktime from the viewer. Generally anything able to be played in Quicktime can be viewed in OpenSimulator through your viewer. Streaming does not impact the performance of the simulator since all content is sent to the viewer and Quicktime player.

Creating a Media Screen in OpenSimulator

Now that you understand some of the fundamentals of what is going on with media content in OpenSimulator you are probably wanting to get started creating a video area so you and your friends can enjoy watching or listening to some media together. The best free script that I have come across is Freeview. The code for this script is listed below and you can simply copy and paste it into a script window to get you started.

General Steps

Make sure you have a texture picked out to use as a media texture. Streaming media has to be displayed on a texture and unless you want to see your media playing all over the place make sure the texture is unique to just the prim you want to use as a view screen. [Note that svn 8118 onwards includes a default media etxture in the standard library, which corresponds with a UUID of 8b5fec65-8d8d-9dc5-cda8-8fdf2716e361 and that corresponds to the LSL constant TEXTURE_MEDIA] [See http://opensimulator.org/mantis/view.php?id=3030]
Create a prim that will display the media.
For a good looking display choose a blank texture with a black color for all sides.
Select just the prim face for the screen and make the texture your media texture from Step 1 and choose white for the color.
Drop the Freeview script into the Contents tab.
In the About Land window Media tab change your Replace Texture to the one in Step 1.
In the About Land window General tab make sure the Allow Deed To Group item is checked.

At this point if your script compiled correctly then you should be able to click on the media view screen and a menu will pop up. A good test would be to choose the Video button and then the Set URL button. In the chat window type /1 and then a URL to a video that you know exists on a streaming server. The video should begin playing within a minute or so.

Tips for Using Freeview

Need some info here.

The domain inside the script and the function inside the menu (TV Guide) are out of date.

Domain slguide.com is without any information, it is park as Free-Domain for register.

Freeview Code

//XEngine:
//FreeView 1.2 WebGuide (revision 3) - By CrystalShard Foo
//Multifunctional Picture viewer and Video control script with webguide support
//This script is distributed for free and must stay that way. 
 
// *** DO NOT SELL THIS SCRIPT UNDER ANY CIRCUMSTANCE. ***
 
//Help for using this script can be obtained at: http://www.slguide.com/help
 
//Feel free to modify this script and post your improvement. Leave the credits intact but feel free to add your name at its bottom.
 
//Whats new:
//- Now using FULL_BRIGHT instead of PRIM_MATERIAL_LIGHT for the screen display
//- Added an ownership-change code to handle cases where FreeView gets deeded to group post Video Init.
//- Renamed WebGuide to TV-Guide to reflect what this thing does better.
//- Added a 'Fix Scale' button to Picture mode to help against user texture-scale changes.
//- Additional minor help-tips and code improvements
 
//Enjoy!
