Requst for info about metavid installation
by ioannis ioannis 29 Nov '12

29 Nov '12

Dear friends, I have recently attempted to implement the metavid / mediawiki solution for educational purposes. My setup consists of a linux host, mediawiki (version 1.20), semantic mediawiki (version 1.7.1) and metavid (version beta 1.0rc1, downloaded from svn). Although mediawiki with semantic mediawiki installed works properly, when metavid is activated in the localsettings file, I get the following two errors: a) When I try to edit a wiki page I get an un-handled exception error. b) The special pages link in mediawiki opens a blank page. I have tried various solutions for this problem that I found in posts from other users, but with no success. I have been unable to locate a document that explains which versions of mediawiki/semantic mediawiki/metavid are the proper ones for a successful installation, can you please point me to any such information so I can implement my project? Regards Ioannis

Re: [MetaVid-l] Call for Ideas: MetaVidWiki + Wikimedia Labs

Hi George, Great work on getting the labs project started. In terms of what a modern incarnation of metavid wiki would look like I think it would tie into wikidata and timed media handler and possibly leverage some of the UI concepts from miro subtitles. We should have a very concrete effort to deploy timed media handler later this month. Timed media handler will support srt wiki hosted text files in the initial release and we can be looking at other temporal metadata formats. Especially in the context of wikidata enabling different content types for stored versioned data with the mediaWiki platfom. Nailing down the data format other tools can be built around that format. Similar to how we supported miro subs tool to update media wiki hosted srts. --michael sent from mobile ----- Reply message ----- From: "George Chriss" <gchriss(a)openmeetings.org> To: "MetaVidWiki Discussion List" <metavid-l(a)lists.wikimedia.org> Cc: "Wikivideo Discussion List" <wikivideo-l(a)lists.wikimedia.org> Subject: [MetaVid-l] Call for Ideas: MetaVidWiki + Wikimedia Labs Date: Thu, Jul 12, 2012 7:30 pm Hi MetaVidWiki-ers (and wikivideo enthusiasts), I'd like to call your attention to the new MetaVidWiki project hosted on Wikimedia Labs: https://labsconsole.wikimedia.org/wiki/Nova_Resource:Metavidwiki Labs is "an environment where users can create and manage entire computing and networking infrastructures" for technical development work related to Wikimedia Foundation (WMF) projects.

Does MetaVidWiki work on Dreamhost?
by Lionel Fogler 23 Mar '11

23 Mar '11

Does MetaVidWiki work on Dreamhost? I did the one-click install and then loaded the metavidwiki extension within the install but I am getting some strange errors. Does dreamhost support annodex? I have a very exciting project for a charity (I am not getting paid) which I am working on and I feel the MetaVidWiki is a perfect platform for it. Over 400 two hour interviews with over 10,000 pages of transcripts which have already been digitized. I am hoping to get the system working so I can can sync the transcripts to the videos and make them searchable and accessible globally. Is this the best platform for this application? Do you know of other platforms which might work like this? Would anyone be able to help me get MetaVidWiki working on Dreamhost so I can test and figure out if this is the best technology to pursue? Thank you Lionel

Thanks! I was entirely unaware of this project. I'm CC'ing the MetaVid list as there is shared interest in making video annotation quick, easy, and fun.

Dear MetaVidWiki team, my name is Angelo Crovace and i'm working on the project for the University of Bologna (Italy), Department of "Musica e Spettacolo". The project consists of a digitalization of the entire movies archives and the visualization of the contents. We have a problem when we install the extension Metavid and in particularry during installing the template. My configuration system is the following MediaWiki 1.16alpha > PHP 5.2.10-2ubuntu6.1 (apache2handler) > MySQL 5.1.37-1ubuntu5 > and the error message that i received when i run "php maintenance/metavid2mvWiki.php update_templates" was: > Warning: require_once(../../../maintenance/commandLine.inc): failed to open > stream: No such file or directory in > /var/lib/mediawiki/extensions/MetavidWiki/maintenance/metavid2mvWiki.php on > line 17 > > Fatal error: require_once(): Failed opening required > '../../../maintenance/commandLine.inc' > (include_path='.:/usr/share/php:/usr/share/pear') in > /var/lib/mediawiki/extensions/MetavidWiki/maintenance/metavid2mvWiki.php on > line 17 > or if i run "php metavid2mvWiki.php update_templates" was: should run on: update_templatesroot@muzzuntu:/var/lib/mediawiki/extensions/MetavidWiki/maintenance# > > Thank you for your help in advance.

Re: [MetaVid-l] Developers for OpenMeetings.org?
by Michael Dale 25 Aug '09

Thanks for you interest in metavid, I really like what you have done with the openmeetings.org site. I would just mention that you really should use a bit smaller granularity in your transcripts. Big text blocks make it difficult to search the transcripts and quickly jump to what your looking for. comments inline: I have cc'ed the metavid-l list. I will try and post this "roadmap" on the wiki sometime soon cuz I realize I have been so busy programing I have not keep people updated with ~the plan~.

There is a lot of work taking place on metavid pieces like the javascript player and the javascript sequencer. This is not necessarily reflected in the extension code as the javascript components have been moved to the trunk. The idea it to as best as possible make every pieces as reusable in a stand alone context as possible, this means a stand alone sequencer / video editor that exports flat files a stand alone skinnable player that can embed ogg video anywhere with a simple script include, a stand alone firefogg encoder to export videos etc. My next major task is to split the extension up into up into separate "stand alone" extensions "Sequencer", "Timed Text", and "Temporal Media Search". ( Will create a "metavidCore" that will hold the shared functions and then re-factor all the existing metavid code into new cleaner versions as stand alone sub extensions. This way a simple check out of metavidWiki running trunk gives you all that functionality. Other "sub-extensions" will be: OggHanlder (handles user uploaded ogg video uploads) WikiAtHome extension (helps distribute transcode and flattening operations, we also want to integrate a bittrorent client with video tag support) "Semantic Media Wiki" (handles semantic properties on videos explained in more detail below) > > There are several areas where development work would be helpful: > > ==User-selectable mirrors== > I prefer to keep the video streams at reasonably-high quality, using Ogg > Theora.

But its better to handle this at the CDN level ... I think ultimately our thin development effort here would be best spent on integrating a media streaming bitttorent client into firefogg. We could add "read only" bittroent for java cortado users, include http seeding support (which works with byte offsets request so traditional servers can be easy to add to the seeding pool). That way you client always tries to download from the fastest peer be it normal http server near by or someone with a fat pipe in Alaska. > Also, I've noticed a "local seek" feature but haven't had time to look at > it in detail. > This basically does a local seek instead of an oggz_chop server request when the media has been loaded up to that point. > > ==Identi.ca== > A good way to increase project visibility would be to integrate Identi.ca > dents (also CC-BY).

The idea to integrate jabber transcrits was also discussed at one point. Aphid may be able to tell you more about that ;) ... I think what we need is a solid API to enable easily building of those types of tools. Unfortunately I built metavid version 1 a while a go and did not structure it as I would have today. Subsequent versions should make it very easy to add layers of transcript data in simple interfaces. Also things like re-capatchca style transcription & translation are key for quick and easy participation. > ==Geo-searching== > I've started to include GPS coordinates with video uploads, such that > visitors could search for meetings by both location and time. > Search-by-location is not yet implemented. > I believe there is some geo-location property work done in semantic wiki. If we can integrate with that effort that would be ideal.

Help? > if you just label speakers its useful ... You can see how its useful maybe you have some video talking /about John Doe/ and some videos /of John Doe talking/. And you want to avoid categorization verbosity with chance of inconsistency of categorization. Ie one person says "spoken by john doe" another tags it with just "john doe" its hard to know what is what. Other things you could semantically tag are things like geo-location (We already put the temporal tag in the wiki temporal annotation title) Only special properties that have semantic meaning like geo-location are ideal for semantic tagging withing the context of timed media attributes. Everything else should fall a category or "tag" not be a semantic property. The real value is combining semantic properties about speakers and or you your case potential geo-location, so show me meeting where John Doe is in Texas speaking about "Free Speech" (where Free Speech is just a category, and John Doe is in Texas are semantic properties. > > ==OLPC XO== > I'm curious to know if playback works on XOs, and if not what it would > take to make this happen. > probably need to innovate on the interface a little make it work with smaller screen, we already support a hardware accelerated rendering via plugins (something the XO needs as it can't decode Firefox video in software very easily) and would be nice to integrate into other features of the device like accepting uploads captured on the device. hope this was helpfull, keep us updated on your efforts, peace, --michael
