Installing metavid extensionon Mediawiki 1.19.3
by Stéphane Couture 13 Mar '13

13 Mar '13

Hello, I tried to install Metavid on MediaWiki 1.19.3 (LTS). Unfortunately, it doesn't work. From what I saw in the archive of this mailing list, and in other forums, it seems that the MetaVid Extension is not maintained anymore. Can someone confirm me that it is the case ? Do you think it is possible to install MetaVid anyway on MediaWiki 1.19.3, without too much work ? . Thank you in advance for your responses. Stéphane

My metavid installation status > as of 18/1/2013

After a couple of months of trial and error and with the kind help of the metavid / mediawiki community, I have successfuly reached a properly working installation comprising of: Installed software Product Version MediaWiki 1.16alpha (r52874) PHP 5.3.2-1ubuntu4.18 (apache2handler) MySQL 5.1.66-0ubuntu0.10.04.3 Installed extensionsSpecial pages Semantic Forms (Version 2.2.1)Forms for adding and editing semantic data ..., Stephan Gambke and Yaron Koren Parser hooks Cite (Version 2008-01-31)Adds <ref[ name=id]> and <references/> tags, for citations Ævar Arnfjörð Bjarmason External Data (Version 0.6.1)Allows for retrieving data in CSV, JSON and XML formats from both external URLs and local wiki pages Michael Dale and Yaron Koren ParserFunctions Enhance parser with logical functions Tim Starling RSS Reader (Version 0.2.3)adds an rss tag Artem Kaznatcheev Semantic MediaWiki (Version 1.4.2)Making your wiki more accessible – for machines and humans.

Only the Form creation had this issue, Templates, properties and categories were properly created by the same special page. I believe that the way I fixed it was adding to LocalSettings.php the following variables: //set up namespace $smwgNamespaceIndex=100; //set metavid namespace to smw namespace + 10 Initially it was +6 $mvNamespaceIndex=$smwgNamespaceIndex + 10; //add the new custom namespace index for Form and Form_talk define("NS_FORM", 500); define("NS_FORM_TALK", 501); $wgExtraNamespaces[NS_FORM] = "Form"; $wgExtraNamespaces[NS_FORM_TALK] = "Form_talk"; Unfortunately, I'm not fully sure that the above changes/additions actually fixed the Form creation problem since I got impatient and performed a couple of changes at once. I will test to see which change actually fixed the issue. The current open issue I'm working on is with the thumbnail creation of videos using ffmpeg. In George's patches 'thumbnailer' is used and I can't find this s/w so I will need to substitute it with ffmpeg thumbnailer . Regards Ioannis

Congratulations on getting this all up and running.

Updated: My metavid installation status > as of 7-12-2012

Hi, after examining the functionality of my installation, I believe that I am missing some templates in order to have the full functionality. For example, I have created a person template with the assistance of George, which shows the person's photo. However, its clear that there should be other variables in this template, which I can not find. Any ideas as to the required templates and their structure? Regards Ioannis

Updated: Solved: My metavid installation status as of 7-12-2012

Dear friends, with your help, I am at a very good point with my installation. Almost all tagging/transcribing functionality works. I do have one more question at this time: When I create a new tag or annotation or transcript, the end time shown in the edit box is always 0:00:30 and not the actual end time (or duration) of the video, and I have to update it by typing in the end time and then adjust with the slider. How can I fix this to show the video's end time by default?

My metavid installation status as of 7-12-2012
by ioannis ioannis 09 Dec '12

09 Dec '12

Dear friends, following the much appreciated support from Michael and George, I finally managed to install and configure a working platform consisting of the following elements: Mediawiki 1.16a r52874 PHP 5.3.2-1ubuntu4.18 (apache2handler) MySQL 5.1.41-3ubuntu2.10 Cite (Version 2008-01-31) ParserFunctions RSS Reader (Version 0.2.3) Semantic MediaWiki (Version 1.3) OggHandler (r42524) MetaVidWiki (Version 1.0r47961) Essentially, the platform is the same as the one on metavid.org site. I am now able to add new streams and tag / transcribe them. My question though has to do with uploading new video content to the site. I have setup all the relevant variables for allowed extensions, file size uploads,etc. If I upload any type of allowed content (i.e. mp4 video, word document, jpeg image) the upload is completed and the new content is available. However, if I try to upload an ogg or ogv file, either directly or by transcoding it by fireogg plugin, the upload does not complete. No errors are produced in the web server or other system logs. Any suggestions on what to look for in order to resolve this ? My current way of uploading content is to copy the file to a folder on the web server and then use the add stream to create a stream and reference to the video file. Also, is there any batch upload / import method available? Regards Ioannis

Hi, Following George's comments, I have worked a bit during the weekend on my installation. With the following configuration in apache2.conf I avoided using the relevant rewrite rules in .htaccess and all seems to work fine <IfModule mod_actions.c> ScriptAlias /oggz-chop /usr/bin/oggz-chop.cgi Action application/ogg /oggz-chop.cgi Action video/ogg /oggz-chop.cgi Action audio/ogg /oggz-chop.cgi Action application/ogv /oggz-chop.cgi Action video/ogv /oggz-chop.cgi Action audio/ogv /oggz-chop.cgi </IfModule> I also created two new pages in mediawiki to cater for the relevant input fields when tagging/annotating a video. Property:Bill & Property:Speech By With the above modifications, I can add new videos and then edit them by adding tags/annotations and transcripts. A few more questions : A) I add a new video from special pages -> metavid add stream I edit the stream and add the video file, also typing in its length, i.e. 0:10:00 However the video (and all videos imported) show a time length of 0:20:00. Any suggestions on how to make the video pages show the actual video length? B) It seems that I am not able to create a Sequence. From the demo video of metavid, It seems that by using a Sequence:ABCD you can create a sequence where videos can be edited in the timeline. How can I enable this? C) In the new transcript part of editing, there seems to be an image of the person making the speech. In my case its always the missing person.jpg. How can I add my custom picture? I do have more questions, but I thinks the above are quite enough for now :) Best Regards Ioannis

Dear friends, after following George's guidelines, I managed to solve most of my installation's problems. I had to make changes in the .htaccess files in the wiki directory and the apache2.conf file to allow CGI operation and excecution. By looking at the apache error log, I also found quite some references to deprecated functions "split" which I changed to "explode" to avoid errors. I also found an error which prevented adding a new tag or transcript and isntead of showing the relevant "forms" when clicked, it showed an endless "loading ..." text. The error is: [Sun Dec 02 09:15:53 2012] [error] [client 127.0.0.1] PHP Fatal error: Call to undefined method MV_EditPageAjax::extractMetaDataFromArticle() in /var/www/mediawiki-1.16.0/extensions/MetavidWiki/includes/MV_MetavidInterface/MV_EditPageAjax.php on line 182, referer: http://localhost/wiki/index.php/Stream:Last-test I tested by commenting out line 182 in MV_EditPageAjax.php and now the new tag an new transcript links work, however I would like to ask for your help on this issue since obviously my solution is not the proper one. With your help, I am progressing really well, since I need to fully understand metavid's functionality in order to contribute to it's update.

Updated: Requst for info about metavid installation‏

Dear friends, please let me update you on my project's status so far after the information and files you provided. I installed mediawiki 1.16, semantic mediawiki 1.3 and metavid1.0r47961 (thanks to Michael for the zipped files) successfully on ubuntu 10.04lts. The older version of ubuntu was used so as to have the correct versions of mysql, php, etc. Now in my wiki's Special:Version page the s/w listed is exactly the same as the one shown in metavid.org site, therefore I consider the two setups to be identical. I successfully managed to add a new stream (test_stream) from a local file (.ogv) on my "server" from Special:MV_Add_Stream The stream can be seen in my "server's" Special:MV_List_Streams. So far so good, but after this step there are some issues for which I again ask for your kind assistance. When I attempt to edit the stream (Stream:Test_stream), I get a page which shows the video embedded as expected and I can play the video as well. However the following links are not operational: Edit Time - upper right corner above the video windowDownload Options - lower left corner under the video windowEmbed Video - lower left corner under the video windowNew tag or Annotation - lower right corner of wiki creenNew transcript - lower right corner of wiki screen Therefore, I am unable to edit or tag the video in the timeline, as shown in the example video in youtube where Michael presents metavid's features. Your help in assisting me on how to resolve these issues would be of great value at this point. Kind regards Ioannis
