Multimedia/Media Viewer/it

Questo è il project hub per Media Viewer, un nuovo strumento in corso di sviluppo da parte del nuovo gruppo multimediale della Wikimedia Foundation. Per una veloce panoramica su questo progetto visita 'A proposito di Media Viewer'.

Questo nuovo browser multimediale mostra le immagini in un formato più grande sui siti Wikipedia e Wikimedia, dove sta gradualmente diventando il sistema di visualizzazione predefinito, come descritto in questo piano di rilascio.

Media Viewer è stato testato estensivamente su molte grandi wiki nel mondo ed i riscontri raccolti da migliaia di utenti suggeriscono che questo strumento è generalmente utile, come evidenziato dai risultati di questa indagine.

Invitiamo anche te a sperimentare Media Viewer: per saperne di più visita questa pagina di aiuto. Dopo aver provato questo strumento ti invitiamo a farci sapere che cosa ne pensi e a unirti a questa discussione. Per partecipare a future discussioni e tenerti aggiornato sul nostro lavoro, sottoscrivi la nostra mailing list multimediale.

Obiettivi






Proposito
Il proposito di questo strumento è quello di:
 * Fornire un'esperienza multimediale più ricca, per venire incontro alle attese dell'utente
 * Mostrare le immagini in un formato più grande, nella stessa pagina in cui si trova la miniatura su cui hai cliccato
 * Ridurre la confusione che si genera quando gli utenti cliccano sulle miniature (saltare la doppia pagina di informazioni sul file sulle Wikipedie)

It aims to serve all users of Wikipedia, Commons and other MediaWiki sites. Note that this media viewer now only supports still images, but we plan to support other file formats such as video, audio and slides in the next version.

Users
Our primary users for Media Viewer are:
 * readers
 * casual editors

Other users include:
 * experienced editors
 * contributors

We aim to support all these user groups, with an initial focus on readers in our first release. See user stories below for each user group.

As a reader, I want to:
 * Reader stories
 * view larger images
 * find basic information
 * browse related images
 * share a link to this file
 * use a simple, uncluttered interface
 * view images on the same page (not another site)
 * get back to the article easily

See thumbnails to the right for current and proposed reader experience. See also our vision for this tool.

As a casual editor, I want to:
 * Casual editor stories
 * find more information
 * see original images

Minimum Viable Product
Features for the minimum viable product include:
 * Show images in larger, media viewer panel when you click on them
 * Modal panel opens up as overlay (on same page where you clicked)
 * Large image appears without clutter, for a more immersive experience
 * Information about the image can be accessed easily
 * Images can be shown in full-screen mode
 * Images in a collection can be browsed easily

Workflow
The thumbnails to the right show the reader workflow we are looking to support:
 * Overview of reader workflows (shown above for reference)
 * Proposed workflow for viewing images with Media Viewer

Lightbox View




Media Viewer provides two different views of an image when you click on its thumbnail on an article page: Lightbox and Full-screen View. The 'Lightbox view' for this tool is described below.

Image
The image is shown in large size against a black background, as an overlay that fills up the entire browser page where you clicked on the thumbnail. This makes the image stand out more and removes some of the visual clutter typically found on a text-heavy page.

In the image view, the browser window will be obscured to hide its contents, but not the entire screen (unlike the Full-screen view where the entire screen will be darkened).

Tools
In this v0.2 release, these tools are provided:
 * Close button (goes back to article view)
 * Full screen button (expands into full-screen view)
 * Next and Previous arrows (to browse through related images)

Primary Info
Here are the most important information fields that will be shown prominently near the image, as shown in the first version of this tool (see mockup):
 * File name (Zonotrichia atricapilla)
 * Author (e.g. Alejandro Erickson)
 * Source (e.g. Bird Institute)
 * License Info (e.g. CC-BY-SA-2.0) (or link to license info)
 * Chevron icon for opening the metadata panel to reveal more info (see below)

The first mockup to the right shows how this information would be presented to the user, to minimize clutter near the image, but still keep important metadata as prominent as possible. Please click on the specific features above to see the latest mockups and specifications.

Secondary Info
Here is the information that is shown below the fold, once you open the metadata panel (by clicking on the chevron or scrolling):
 * Description
 * Site name and link (e.g. 'Learn more on Wikimedia Commons')
 * Uploader name (e.g. Smallbones)
 * Creation Date (e.g. 12 April, 2012)
 * Location (e.g. place name and/or geotag coordinates, if any)
 * Categories (e.g. Birds of British Columbia, Zonotrichia atricapilla … more> )
 * File usage (e.g. 'This file is being used by 5 other pages. ')
 * Permissions (e.g. special credits or restrictions)
 * Assessment credit (e.g. '')
 * More meta-data may be added to this panel over time, as proposed below
 * File format / size (e.g. JPEG, 4928 x 3264 px (more), 3.8 Mb)
 * Tool used for upload (e.g. 'Via Flickr')

The second mockup to the right shows how this information would be presented to the user, to minimize clutter near the image, but still keep important metadata as prominent as possible. Please click on the specific features above to see the latest mockups and specifications.

Full-screen View


The 'full-screen view' for this tool will show a large image across the entire screen, with minimal information and buttons available on hover. This is the view that lets you focus exclusively on the image, with no other distractions.

Full image
When you click on the full screen icon, you see the largest version of the image that fits within the user's entire screen (not just the browser window).

Information
In this mode, you only see the controls, the file name and the author/source/license if you hover over the image.

If desired by users, it may be possible to include more information below the image, available by scrolling down.

New Tools




We are now working on these new tools and features for version v0.2:
 * Use/share this file (screenshot)
 * Embed this file (screenshot)
 * Download this file (screenshot)
 * Access Media Viewer on Commons

We're also working on a range of other features such as faster image load and better user interface. We invite you to test and discuss features in development, so we can improve them based on your feedback. Please join this discussion about Media Viewer, where new features are regularly listed. We would love it if you could try the ones labeled ‘ready for testing’. You can also review our specifications for features that are ‘coming soon’ — and hope you can help test them as well later this month (we release new code every Thursday).

Current Release
Media Viewer 0.2 is being gradually released worldwide. This deployment started with limited tests on a few pilot sites in April 2014, then wider releases in May 2014. Media Viewer is now scheduled to be released on all wikis by mid-June, as described in this release plan.

To prepare for this release, we invite you to test the latest version on this demo page on MediaWiki.org or on your home wiki. If your site has not yet enabled Media Viewer by default, you can enable it as a Beta feature in your preferences), as outlined in the next section. Learn more in this help page.

How can I help?


Can you help test Media Viewer in coming days? You can try the latest version on this demo page on MediaWiki.org, or test earlier versions on your home wiki.

If Media Viewer has not yet been enabled by default on your wiki, you can test it as a Beta Feature: click on the small 'Beta' link next to 'Preferences' in your personal menu. Then check the box next to 'Media Viewer' in the Beta Features section of your user preferences — and click 'Save' (see screenshot). You can turn off any this option anytime, by reversing these steps. Learn more in this help page.

After you've tried Media Viewer, please let us know what you think on this discussion page. If you find any technical bugs, please [//bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions&component=MultimediaViewer report them here on Bugzilla].

Try out Media Viewer and let us know what you think on this discussion page. If you find any technical bugs, please [//bugzilla.wikimedia.org/enter_bug.cgi?product=MediaWiki%20extensions&component=MultimediaViewer report them here on Bugzilla].

Tens of thousands of beta testers have now tried Media Viewer around the world. Here is an overview of the feedback they have kindly given us to help improve this tool. Many of their suggestions have been implemented (or are about to), as part of our current release plan.

Note: in this current release, the Media Viewer will only support the most widely used image file formats (e.g.: JPEG, GIF, PNG, TIFF, SVG). In future releases, we plan to add support for more file formats, such as PDF, audio and video files. See the next section.

Next Versions


The next version 0.3 of Media Viewer will focus on zooming on large images and adding more features requested by our community. And version 0.4 will support more file formats (e.g. slides, video, audio). For an overview of what we're considering for these future versions, check our 2016 multimedia vision, as well as our annual plan for multimedia in 2014-15.

Here are some features we are considering for future versions:
 * Zoom on this file
 * Show file collection panel
 * View files in slideshow mode
 * Show PDF slides
 * Play Video files
 * Play Audio files
 * Support Developer Plugins
 * Mobile Version of Media Viewer

A consistent user interface will be provided for time-based and audio-video playback tools above (play/pause, rewind, volume, timeline). In future versions, we plan to provide more feedback tools below the image (e.g. thank, flag), as suggested by best practices from other media sites. We will also start working on mobile versions of the Media Viewer, in collaboration with the mobile team.

Desktop Mockups
Here are some preliminary mockups of designs we're exploring for desktop computers.

These mockups will be adjusted based on community feedback.

Future releases
For future releases beyond this fiscal year, we are considering these features:
 * Watchlist (add this file to your watchlist)
 * Thanks (send notification to uploader to show appreciation, through notifications)
 * Flag (reports this file as inappropriate on Commons)
 * Tag (tag this file with a new category, geolocation or intersecting tags)
 * Related files button (show thumbnails of files in same gallery/category)
 * Add Category button (for categorizing files in Media Viewer)
 * Discussion button? (goes to Commons talk page)
 * Edit button? (goes to Commons edit page)

These tools would help users take action on the media they are viewing. For example, a user might want to add a file to their watchlist, or thank the person who uploaded the file, flag a file as inappropriate, tag it with a new category, etc. These tools could be offered in a toolbar below the image, or further down in the metadata panel.

Feedback
Here is some of the feedback we have received about Media Viewer since its deployment in early November. We have already implemented or are working on many of these recommendations (see Tasks below) and will update this section again based on feedback received after the global deployment of Media Viewer 2.0.

Favorable Responses

 * Very clean and useful! (Kelvinsong)


 * [Glad you're working on] a better media viewer. (Amada44)


 * I is nice I can enlarge thumbnails wihtout having to go to another page. (Arcane21, Cornel24)


 * I like that I can see all the most relevant information about the image in 1 page only and the graphic display. (Daniele Pugliesi)

Recommendations for improvement

 * Performance
 * Really slow -- slower than loading the file page. (Mono, Arcane21, Ragesoss, Another Believer, Daniele Pugliesi, Cornel24, Holger1959)


 * Style and layout
 * The transparent background against the file information is distracting. I would prefer that the text have an opaque background -- preferably darker. (Ragesoss, Another Believer, equazcion, Daniele Pugliesi, Cornel24, Kelvinsong, Daniele Pugliesi)
 * 'Use This File' popup could be prettier. (Kelvinsong)
 * Smiley face in front of 'Uploaded by' is confusing, should use an arrow instead (Ainali, Daniele Pugliesi)
 * I expected the closing X on the top right position, not left (Barcex, Raymond, Gryllida)
 * Image size
 * Zooming would be useful. There is no obvious interface for getting to a larger version or the original media file. (FocalPoint, Daniele Pugliesi, Michael Z.)
 * Quicklinks to other image sizes are a must. (MarkJurgens, Daniele Pugliesi, Elitre)
 * I'd make the initial view/popup show a larger image size. (MarkJurgens, Daniele Pugliesi, Frank Schulenburg)
 * The file information should be balanced centrally with the image, instead of jutting to the left. (Ragesoss)
 * Add more clearly visible link to file info. (Gryllida)


 * Text, interface, content
 * Integrate 'Use this File' link -- to attribute files correctly, with a quick summary of author, source and license. (Amada44, Elitre, Church of emacs, Rsocol)
 * "Use this file" menu should have the option to "copy to clipboard" to be used together with the VisualEditor. (Micru)
 * Add left and right arrows to navigate to other media in the article. (Micru, Daniele Pugliesi)
 * It could be nice to see a slideshow of the images in the same Commons category or in the same Wikipedia page. (Daniele Pugliesi)
 * 'Created by' date above the uploader name is confusing for old images (Ainali)


 * Bugs
 * Each field has its own issues mostly due large variety of Commons:Infoboxes and how they are used. Here are detailed recommendations for each (Jarekt, Elitre)
 * Support for multiple page documents (Djvu, PDF, PPT, etc). (Micru, Gryllida)


 * Simply adjust the settings in preferences (appearance / file) for quick viewing … for a result better and faster than what is proposed by this beta. (Archaeodontosaurus)

Based on this feedback, development tasks for Media Viewer are regularly added to the Multimedia team's Mingle project management site.

Other Feedback
Two RfCs (in English Wikipedia and Wikimedia) were initiated, the response of which overwhelmingly indicated that contributors, both regular and occasional, believe that the "Media Viewer" should be disabled by default for all users, logged-in or not, and either left as an opt-in feature or scrapped altogether.

Aside from any technical shortcomings, discontent was also shown with the manner in which the project was conducted and the lack of transparency shown by the team responsible.

Code
Our work in progress can be viewed on this beta site, where new features are rolled out all the time (you'll need to create a test account to log-in and use the Beta Features preference, as described in the 'How can I help' section above.)

The code for Media Viewer is made possible by two separate extensions:
 * Multimedia Viewer Extension - the front-end extension that displays media files and information
 * Commons Meta Data - the back-end API that serves information to the Media Viewer
