Media Plugin

Embed multimedia objects such as Flash or QuickTime in topics.

Uses the OBJECT html tag to embed arbitrary content into a page, with a particular bent towards media: common media formats are detected and some "agnostic best-guess" html is used (derived from that recommended by the plugin providers). However, any content can be embedded using the object tag: java, pdf, other html, svg, even images (although for the latter is of course no real reason to do so this way). The plugin uses generic syntax when it cannot detect the type of file being embedded.

The plugin stores a range of default values (defined here on this page) which allow you to specify a bare minimum of info in your markup and still get acceptable results (see Basic Usage below). These defaults can of course be overridden on a use-by-use basis.

Basic Usage

You could call the plugin as simply as:


This will detect that the embedded file is a QuickTime and use "media-like" syntax (and pass the correct classid to IE - why it can't work out which plugin to use is a little beyond me). However, unlike an IMG tag, plugins do not autosize to their content, and the movie would display at the default size. You could use media of only one size site-wide and specify the dimensions as defaults, but realistically the minimum markup you need to embed things into your wiki pages is:

%MEDIA{"SomeMovie.swf" width="320" height="180"}%

Advanced Usage

A call to the MediaPlugin could get as complicated as:


See for possible attributes below.

Note that MediaPlugin figures out the correct mime type parameter so that the correct plugin will be called to deal with that content.


MediaPlugin supports arbitrary parameters. If you pass it cowtype="Jersey", it will passed on to the browser.

A few parameters are defined and get handled a little differently (they may be "translated" to a particular browser plugins syntax).

Parameter Value Description Notes
"", src, data URI or file name The content to embed. Relative URIs are interpreted with respect to the codebase attribute if it is given.  
width Standard web measure (px, %, em) Width of box holding content  
height Standard web measure (px, %, em) Height of box holding content  
controller text boolean ("TRUE" or "FALSE") Whether to display controls automatically added
play text boolean whether to auto-play the content Automatically added for QuickTime and Flash

Syntax for QuickTime mov

See Overview of Embed Tag Attributes for QuickTime.

Syntax for Flash swf

Pass Flash movie attributes within the %MEDIA{...}% accolades (all values within quotes). When a particular parameter is not specified, the default value will be used (see table below).

Parameter Description Example
Required attributes
src Filepath of the movie; should have suffix .swf ("src=" can be omitted) mypath/flashmovie.swf
General attributes
width Width of Flash movie in pixels, or a percentage. 100% means one hundred percent of the available width on the page. "50%" or "500px"
height Height of Flash movie in pixels, or a percentage. 100% means one hundred percent of the available height on the page. "50%" or "500px"
bgcolor Background color of Flash movie in hex string. When omitted, no background color will be specified and the background color of the Flash movie will be used. "#cccccc"
Advanced attributes
align Default centers the movie in the browser window and crops edges if the browser window is smaller than the movie. l (left), r (right), t (top), and b (bottom) align the movie along the corresponding edge of the browser window and crop the remaining three sides as needed. "l", "r", "t", "b"
salign l, r, t, and b align the movie along the left, right, top or bottom edge, respectively, of the browser window and crop the remaining three sides as needed.
tl and tr align the movie to the top left and top right corner, respectively, of the browser window and crop the bottom and remaining right or left side as needed.
bl and br align the movie to the bottom left and bottom right corner, respectively, of the browser window and crop the top and remaining right or left side as needed.
"l", "t", "r", "b", "tl", "tr", "bl", "br"
scale Scaling of Flash movie. "noborder", "exactfit", "noscale", "showall"
quality Playback quality. "best", "high", "medium", "low", "autohigh", "autolow"
menu Should right-click on Flash movie show a (default) menu? Note that with the Flash 7 player the menu cannot be removed. "true" or "false"
id ID of Flash movie; should be the same value as name (specify both) "movie2"
wmode Sets the Window Mode property of the Flash movie for transparency, layering, and positioning in the browser.
window - movie plays in its own rectangular window on a web page.
opaque - the movie hides everything on the page behind it.
transparent - the background of the HTML page shows through all transparent portions of the movie, this may slow animation performance.
"window", "opaque" or "transparent"
play Specifies whether the movie begins playing immediately on loading in the browser. "true" or "false"
loop Specifies whether the movie repeats indefinitely or stops when it reaches the last frame. "true" or "false"
allowscriptaccess Controls the ability to perform outbound scripting from within a Flash SWF.
When allowScriptAccess is never, outbound scripting always fails.
When allowScriptAccess is always, outbound scripting always succeeds.
If allowScriptAccess is sameDomain (it is supported in SWFs from Flash Player 8), outbound scripting is allowed only if the SWF file resides in the same domain as the hosting web page.
"sameDomain", "always" or "never"
fullscreen Enabled scriptable fullscreen mode. An overlay dialog box will appear when the movie enters full-screen mode, instructing the user how to exit and return to normal mode. The dialog box appears for a few seconds and then fades out. "true" or "false"
base Specifies the base directory or URL used to resolve all relative path statements in the Flash Player movie. This attribute is helpful when your Flash Player movies are kept in a different directory from your other files. any directory URL, or empty string ""
swliveconnect Specifies whether the browser should start Java when loading the Flash Player for the first time. "true" or "false"
flashvars Variables to be passed to the Flash movie. Multiple variables are separated by &. flashvars="x=50&y=100&url=%ATTACHURL%/picture.jpg"

Syntax for generic objects

The attributes described at Syntax above is mostly all you need. For advanced usage see the table below.

Parameter Value Description
align left, right, top, bottom Defines the text alignment around the object
archive URL A space separated list of URL's to archives. The archives contains resources relevant to the object
border pixels Defines a border around the object
classid class ID Defines a class ID value as set in the Windows Registry or a URL
codebase URL Defines where to find the code for the object
codetype MIME type The internet media type of the code referred to by the classid attribute
data URL Defines a URL that refers to the object's data

Syntax for wmv

Sorry - I could not find any page for this.






By default the controller is shown (unless attribute controller="false"), and the controller height (16px) is automatically added to the movie height.



swf with params

These are just a number of example parameters; not all are effective in this movie.

Notes for developers

The plugin detects most media types and uses a hybrid of the html markup recommended by the browser plugin makers - in the hope of providing maximum compatibility. This is done simply by checking the extension of the filename. Or, if the filename contains youtube.com it will automatically use Flash.

Originally, the plugin used (almost) the exact recommended HTML on a type-by-type basis, but I've abandoned this in favor of "one markup fits all" because you don't know which plugin will be handling what - the various ISO formats (MPEG1,2,4, MP3) will be taken by whatever plugin was installed last, and QuickTime now handles Windows Media on Macintosh systems (at Microsoft's recommendation!).

While most of the HTML is as generic as possible, the classid value and some other mime-type information is unique to a particular file-type, and for Flash, QuickTime and Windows Media the Microsoft-sanctioned values are sent. I understand MSIE has to have this info or it totally burns ...

I haven't bothered with Real. If there's huge demand, it wouldn't be hard to add - but it may also be handled quite well by the generic media syntax already.

Defining additional file formats

The output of this plugin is partially governed by Foswiki templates. The mov file output is defined in templates/objectplugin_mov.tmpl:
Placeholders {MP_...} are replaced by %MEDIA{...}% parameters.

To add other types add your own template using the same naming scheme (objectplugin_ext.tmpl).

Plugin Settings

Change default settings in configure.

Configure setting Meaning Default
{Width} Default width of player 320
{Height} Default height of player 180
{ShowController} Switch that defines if the controller is shown 1
{AutoPlay} Switch that defines if the media is played automatically 1
{Debug} If set to 1, writes debugging info to data/debug.txt 0

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. Use "Find More Extensions" to get a list of available extensions. Select "Install".

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See http://foswiki.org/Support/ManuallyInstallingExtensions for more help.
