Improved video support imminent and Wikidata.org live

TimedMediaHandler coming this week

A 2011 video featuring Jimmy Wales. Depending on when you read this, you'll either see the old video player or the new one, instantly recognisable by way of the large play button in the middle of the video.

The TimedMediaHandler extension (TMH), which brings dramatic improvements to MediaWiki's video handling capabilities, will go live to the English Wikipedia this week following a long and turbulent development, WMF Director of Platform Engineering Rob Lanphier announced on Monday (and later clarified).

The extension, which has been under development for the best part of two years, will introduce a new interface with subtitle support and a simple "|start=2.3|end=5" syntax for extracting video segments. Other features listed include "multi-format multi-bitrate transcoding with auto source selection, ... gallery and search pop-up players, viral iframe sharing / embedding, etc." although it is unclear how many of these will be available at launch. Deployments to other wikis and Commons have been pencilled in for the coming fortnight.

Readers with longer memories will note that some of these features have already surfaced in the 2009-released mwEmbed gadget, the development of which preceded work on TimedMediaHandler. The two have in common a number of features, most notably their choice of default interface – "Kaltura" video player, which was developed starting in January 2008 with assistance from the for-profit company of the same name and demoed at Wikimania 2009 (see contemporary Signpost coverage). The development path since mwEmbed has focussed on performance, security and code review concerns. Accompanying work has focussed on serving video more efficiently and it is likely that any TMH deployment will also make the possibility of accepting a larger number of video input formats a more attractive option to Wikimedia decision makers.

The deployment, should it go according to plan, is likely to be warmly welcomed by developers and readers alike. Among more seasoned developers, however, the smiles will surely be borne less from joy and more from relief that a project spanning four-and-a-half years of legal concerns, technical debates over code quality, endless technical delays and an uncertain payment structure has finally come to fruition.

In brief

Signpost poll

Wikivoyage

You can now give your opinion on next week's poll: In my opinion, videos are...?

Not all fixes may have gone live to WMF sites at the time of writing; some may not be scheduled to go live for several weeks.

Wikidata.org goes live: Wikidata.org (interface in English), a new repository designed to host interwiki links, launched this week and will begin accepting links shortly. The site, which is one half of the forthcoming Wikidata trial (the other half being the Wikidata client, which will be deployed to the Hungarian Wikipedia shortly) will also act as a testing area for phase 2 of Wikidata (centralised data storage). The longer term plan is for Wikidata.org to become a "Wikimedia Commons for data" as phases 2 and 3 (dynamic lists) are developed, project managers say.
IE8 users face 18 JavaScript-free hours: Visitors to the English Wikipedia using Microsoft Internet Explorer 8 (IE8) were left without any site or user JavaScript on Friday for approximately 18 hours after a bug was introduced by WMF developers working on editor engagement (bug #41428). Responding, WMF Quality Assurance Lead Chris McMahon described how the issue has "prompted a lot of discussion within WMF and we are changing some priorities and procedures as a result", including introducing more stopgap protection before a full beta cluster-based JavaScript testing suite comes online. IE8 accounts for roughly 13% of web traffic and 8% of current Wikipedia traffic. In related news, other English Wikipedia editors experienced similar problems due to a JavaScript problem in version 5 of the Article Feedback tool.
Windows 8 app released: Early adopters of the newly released Windows 8 operating system will be able to download a Wikipedia app from the Microsoft app store, it was announced this week (Wikimedia blog). The app, which integrates with system search, shares much of its infrastructure with the other WMF developed apps for the Android and iOS platforms but adopts a design style more in-keeping with the Windows 8 GUI. Peak Windows 8 usage is expected to lie in the hundreds of millions of devices, with the operating system being installed not only onto traditional desktop and laptop computers but also a rapidly increasing number of tablets and smartphones. In related news, the WMF also reported strong visitor growth in its Wikipedia Zero project, which aims to make accessing Wikipedia exempt from data charges in developing countries.
Understanding the international design process: In an insightful post on the Wikimedia blog, WMF User Interface/Experience (UI/UX) developers Arun Ganesh and Pau Giner described the way they conducted user testing for the Universal Language Selector (ULS) project, which helps users translate MediaWiki's interface and select their preferred script input method. The inherent need for the project to be tested on editors from languages other than English presented its own challenges, Ganesh and Giner write, describing how (for example) it prompted developers to adopt a digital form of traditional "paper prototype" that could hence be tested on users remotely. Relatedly, i18n specialist Niklas Laxtröm also blogged this week, describing the problem MediaWiki faces trying to properly localise interface messages involving variable numerical elements.
WMF hires: This week saw the announcement that English Wikipedia Bot Approvals Group member Brad Jorsch (User:Anomie) has been hired to work on "the robustness of the beta cluster" and help with code review (wikitech-l mailing list). New staff who have been accidentally omitted from the pages of the Signpost over the past month include Željko Filipin as a QA Engineer, Michelle Grover as a QA contractor for the Mobile Team and Andre Klapper in a bug oversight role similar to that of former bugmeister Mark Hershberger, who left the Foundation in May to pursue other interests. Jorsch has also been granted merge permissions over core, as have two other volunteers, bringing the number of volunteers with merge rights temporarily to eight (seven plus Jorsch).

Fantastic to hear about the video player. Now all we need to do is increase the maximum file size that the servers accept for .ogv files so that we can upload longer and higher quality segments. For your next media player overhaul, may I suggest the horribly dysfunctional player for audio recordings? This is also Sven Manguard 14:43, 31 October 2012 (UTC)[reply]
- I believe TMH also changes the audio player (but don't quote me on that). Bawolff (talk) 19:59, 31 October 2012 (UTC)[reply]
- THM does in fact update the audio player as well. It outputs the <audio /> tag in the html output. The player is then rewritten by the javascript library, and you can even associate text tracks with audio files for timed display of audio text content with wiki links ( if desired ) mdale (talk) 20:26, 31 October 2012 (UTC)[reply]
  - It does! I'm so happy. I wonder why I was seeing the new video player two days before I was seeing the new audio player though. Sven Manguard Wha? 22:05, 4 November 2012 (UTC)[reply]
Any reason you linked to gossamer-threads rather than lists.wikimedia.org? - David Gerard (talk) 14:58, 31 October 2012 (UTC)[reply]
- I've done it that way since I took over writing the Tech Report full time (i.e. for the last two and a half years); I'm pretty sure I inherited it from one of my predecessors. In any case, I read wikitech-l on Gossamer-Threads, so it's more work to track down the pipermail URLs (which we know can change from time to time) than just leave the neatly threaded Gossamer-URLs. - Jarry1250 ^{[Deliberation needed]} 20:14, 31 October 2012 (UTC)[reply]
  - The UI at http://lists.wikimedia.org/pipermail/wikitech-l/ (etc) is awful. The mirror at http://www.gossamer-threads.com/lists/wiki/wikitech/ is far from perfect, but it is much better. Why do so many techies put up with such poor UI for their discussions?! (Similar issues apply to talk pages, where newbies would benefit from simple in-place replies, like those implemented on Reddit.) Are there no better off-the-shelf alternatives for viewing threaded discussions on the web? Ajax ought to make browsing mailing lists much easier. — Richardguk (talk) 21:52, 31 October 2012 (UTC)[reply]
    - For the most part, techies don't. Most technical types subscribe to the mailing list, and read the messages in the email client of their choice. --Carnildo (talk) 22:40, 31 October 2012 (UTC)[reply]
- I'd add that gossamer links are probably more stable than pipermail's, which are sometimes corrupted when the archives are rebuilt. guillom 13:10, 1 November 2012 (UTC)[reply]
Will this support WebM format? Hopefully there will be a blog post or new page detailing the new features in an easy-to-read format (and with pictures!) 155.201.35.58 (talk) 19:03, 31 October 2012 (UTC)[reply]
- The player supports WebM and WebM is enable on test wiki for TMH - but I doubt it. That will probably come later. - Jarry1250 ^{[Deliberationneeded]} 20:14, 31 October 2012 (UTC)[reply]
- WebM support will be added as soon as its enabled on commons, for ease of rollback we are enabling wiki consumers of commons first ( since WebM supports ogg ) but oggHandler does not support WebM mdale (talk) 20:22, 31 October 2012 (UTC)[reply]
"ability to pick where from a video the thumbnail is drawn" - I think ogghandler supported that as well, just nobody used it. Bawolff (talk) 19:57, 31 October 2012 (UTC)[reply]
- So it did (does). You learn something new every day! - Jarry1250 ^{[Deliberation needed]} 20:14, 31 October 2012 (UTC)[reply]
- TMH adds support for setting a start / stop point in the video itself as well as choosing the thumbnail mdale (talk) —Preceding undated comment added 20:23, 31 October 2012 (UTC)[reply]
What happened regarding the dispute to shutdown the Toolserver? I haven't heard anything about it over the last few weeks. --Nathan2055^{talk - contribs} 16:26, 1 November 2012 (UTC)[reply]

well, we reported the procedural state of affairs on october 15 :). the chapter's assembly will vote on the matter on november 24, regards --Jan eissfeldt (talk) 08:57, 3 November 2012 (UTC)[reply]

Does this version support during-playback selectable resolutions (selectable files, really) for low- and high- bandwidth viewing? If not, is this planned? --Lexein (talk) 00:42, 7 November 2012 (UTC)[reply]
