Embedding Adobe Shockwave Videos

Embedding Shockwave in a Mediawiki page

You can create and embed Adobe Shockwave videos in MediaWiki. This is only possible if $wgRawHtml is true in the configuration of the Mediawiki system. Note that this is a safety issue and therefore requires $wgWhitelistEdit to be true as well.

  1. Create a public directory for the web-server.
  2. Get Jeroen Wijering's free and open source JW_FLV_Player and copy the file flvplayer.swf into this directory.
  3. Convert your video to Shockwave using MEncoder and store the result in the same directory.
  4. Use MPlayer with option -vo jpeg to create a preview image.
  5. Use the tags html and embed to embed the video in a page.

This is the command line for creating a Shockwave video (FLV):

mencoder input.avi -o output.flv -of lavf \
    -oac mp3lame -lameopts abr:br=56 -srate 22050 -ovc lavc \
    -lavcopts vcodec=flv:vbitrate=500:mbd=2:mv0:trell:v4mv:cbp:last_pred=3

You may have to specify -lavfopts i_certify_that_my_video_stream_does_not_use_b_frames as additional parameter.

This is some example HTML-code for embedding a Shockwave video in a page of the Mediawiki:

<html>
  <div class="thumb tright">
    <div style="width:360px;">
      <embed style="width:360px; height:270px;" id="VideoPlayback" type="application/x-shockwave-flash"
        src="http://vision.eng.shu.ac.uk/jan/foodautomation/flvplayer.swf" width="360" height="270"
        flashvars="file=http://vision.eng.shu.ac.uk/mypath/myvideo.flv&image=http://vision.eng.shu.ac.uk/mypath/mypreview.jpg&displayheight=270"/>
      <div class="thumbcaption" >
        This is my description. <a href="Wikipage">And here's a link to another page ...</a>
      </div>
    </div>
