how to write embed code in dekiscript-xml

**harijay** · 04-01-2008 04:52 AM

Hi everyone,
I am looking to write an extension that embeds videos from a custom location using a dekiscript xml-rpc service.

The embed code I wish to return is something like given below. I am new to dekiscript xml and want to know how to wrap that message so that the wiki treats it as html and embeds the flashplayer object.

I cannot use the media extension since I want to do a little more than just embed the movie . Besides I wanted to make sure I understand how the rpc message needs to be constructed in my python app.

Thanks in advace. The raw "dummy" embed code is given below.

<embed
src="mediaplayer.swf"
width="640"
height="480"
allowscriptaccess="always"
allowfullscreen="true"
flashvars="height=480&width=640&file=http://www.myvideosource.com/1/3c27578b9ad280a4e311466eaf9a62be.flv"
/>

If you want to see how you would write that kind of extension in C#, take a look at the media extension source code.

To use DekiScript, you could start with something like:

Code:

<extension>
  <namespace></namespace>

  <function>
    <name>custommedia</name>
    <description>Returns an embedded video</description>
    <param name="video" type = "uri">video uri</param>
    <param name="width" type ="int">video width</param>
    <param name="height" type ="int">video height</param>
    <return>
      <html xmlns:eval="http://mindtouch.com/2007/dekiscript">
        <body>
          <embed
            src="mediaplayer.swf"
            eval:width="args.width"
            eval:height="args.height"
            allowscriptaccess="always"
            allowfullscreen="true"
eval:flashvars="'height='..args.height..'&amp;width='..args.width..'&amp;file='..args.video"
        />
        </body>
      </html>
    </return>
  </function>
</extension>

To re gister:
Make sure to specify that it is a local service and type Extension.
SID = http://services.mindtouch.com/deki/d.../12/dekiscript
Add this config setting: manifest=<path>, where <path> is the location of the file containing the xml above.

Hey Thanks a tonne. I wrote a CGIHTTPServer.CGIHTTPRequestHandler class in python that sends the embed code wrapped in XML as required by the schema posted at http://wiki.opengarden.org/Deki_Wiki...g_languages%3f

The HTTP-POST returns the following with the embed code wrapped as a type "list".
This seemed a little funky i.e I first needed to use <value type="list"> before I used <value type="xml"> to wrap the html embed tag.

The POST stuff is pasted below. Thanks for your help

<value type="list"><value type="xml">
<html xmlns:eval="http://mindtouch.com/2007/dekiscript">
<body>
<embed
src="http://www.code-itch.com/flashplayer/mediaplayer.swf"
width="640"
height="480"
allowscriptaccess="always"
allowfullscreen="true"
flashvars="height=480&width=640&file=http://www.bioscreencast.com/screencasts/150/872c43e328ac398ba84624c46b61936b.flv"/>
</body>
</html></value></value>
