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.
- Create a public directory for the web-server.
- Get Jeroen Wijering's free and open source JW_FLV_Player and copy the file flvplayer.swf into this directory.
- Convert your video to Shockwave using MEncoder and store the result in the same directory.
- Use MPlayer with option -vo jpeg to create a preview image.
- Use the tags html and embed to embed the video in a page.
This is an example for a command line creating a Shockwave video (FLV):
mencoder input.avi -o output.flv -vop scale -zoom -xy 320 -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:keyint=6
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/mypath/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"
pluginspage="http://www.macromedia.com/go/getflashplayer"/>
<div class="thumbcaption" >
This is my description. <a href="Wikipage">And here's a link to another page ...</a>
