There are a few extensions that do embedding video from videosharing portals. I was looking for an extension that does uploading one`s own videos.
MediawikiPlayer extension worked. It integrates jwPlayer and tolerates flash compatible formats.
I also tried metavid installation on Mediawiki 1.16.2, without success.
The following problems occurred:
1) PHP Fatal error: Call to undefined method OutputPage::addScriptClass() in ../MV_GlobalFunctions.php on line 309
With this error Mediawiki-Site (http://www.el.rub.de/rubel) was not accessible.
In MV_GlobalFunctions.php I changed addScriptClass to addScriptFile
$wgOut->addScriptFile( „mv_allpages“ );
$wgOut->addScriptFile( „mv_search“ );
This made Mediawiki-Site accessible again, only Special Pages stayed blank.
2) On Special Pages I got this error:
PHP Fatal error: Cannot redeclare class MV_SpecialListStreams in …/MV_SpecialListStreams.php
I deleted class MV_SpecialListStreams extends QueryPage in MV_SpecialListStreams.php
As a result Special Pages showed up with MetaVid-Pages, not all of them working.
3) I could add a Stream but not access it, again blank page. For this I got another error:
PHP Fatal error: Argument 2 passed to SMWSQLStore2::getPropertyValues() must be an instance of SMWPropertyValue, called in …/MV_MetavidInterface/MV_MetavidInterface.php on line 129
and defined in …/SemanticMediaWiki/includes/storage/SMW_SQLStore2.php on line 226
At this point I stopped. Will give it a try perhaps later.
The Open Video Archive of the US Congress is done with Metavid. It is also referred to by Kaltura Open Source Video: http://www.kaltura.org/project/metavid_semantic_wiki_extension.
