Support of WebM files

Hello.

When the support of WebM files will be available ? --ComputerHotline (talk) 09:47, 16 May 2012 (UTC)

WebM support, as indicated in COM:WEBM, is tied to the deployment of the mw:TimedMediaHandler extension. You can see the status updates on this page. Jean-Fred (talk) 12:34, 16 May 2012 (UTC)

OpenDocument for wikibooks

I know it has been requested before but not with this particular reason. I need to upload some kind of editable document file for "my" wikibook (In Swedish: http://sv.wikibooks.org/wiki/Matematik_f%C3%B6r_%C3%A5rskurs_7-9/). More specifically ods-files as examles (as it is a math book) and some kind of editable odt document. If a specific file is just to be read or printed then I could just use a normal page or a pdf but if I am to make something that the reader can download and start to edit (such as a work sheets) then those formats wont do and odt would be good. If I also do make some odp files that I would like to share to be used by other teachers then that format might be needed too. I hope someone could help me raise this question or give me some alternate solution. Averater (talk) 12:03, 10 November 2012 (UTC)

Found this: https://bugzilla.wikimedia.org/show_bug.cgi?id=2089 . It seems the same reason has been raised before (since 2005!). But I still need help finding a good solution of how to add these kind of files to my wikibook. Averater (talk) 12:16, 10 November 2012 (UTC)

Maybe you could use http://commonsarchive.org/wiki/Main_Page as an alternative. --McZusatz (talk) 12:25, 10 November 2012 (UTC)

"hard limit of 12.5 megapixels" for PNG and GIF

This was actually raised a few months back (though not for animated GIFs?)... AnonMoos (talk) 07:21, 18 December 2012 (UTC)

Compression

Regarding compression for PDF files: I'm thinking about uploading rather big files of book scans in PDF format, not for viewing but for downloading. It would be ressource saving on both ends to have them compressed (e.g. GZIP-Format). Is this ok & if not, where is the problem? --WolfgangRieger (talk) 16:32, 28 February 2013 (UTC)

Gzip is not allowed because you can basically put everything into it. (Viruses as well) --McZusatz (talk) 18:12, 28 February 2013 (UTC)

Does not compute ... The contents could easily be checked for allowed file types only. BTW, PDFs can also have harmful content. --WolfgangRieger (talk) 19:20, 28 February 2013 (UTC)

Also files should be able to be embedded into articles directly. .gz wont allow thumbnails. --McZusatz (talk) 23:09, 28 February 2013 (UTC)

WolfgangRieger -- since PDF version 1.2, PDF can have internal "Flate" compression, which is the same algorithm as used in gzip. Also, in many cases, the content of HTTP messages delivered across the Internet can be gzipped and gunzipped on the fly... AnonMoos (talk) 02:57, 1 March 2013 (UTC)

Sorry, I was not thinking. The contained image data of the scans is already compressed and there would be no big saving. Silly me. --WolfgangRieger (talk) 09:41, 1 March 2013 (UTC)

Any priority for Google Summer of Code projects?

The Wikimedia Foundation is planning to participate again at Google Summer of Code. There is a discussion about proposing projects to support x3d or KML in Commons. What about having a catch-all entry for unsupported file types in Commons/MediaWiki? We could explicitly point to KML, x3d and link to the full list here. Are there other formats that we should highlight to potential GSOC students? Also if you want to volunteer as mentor that would be great.--Qgil (talk) 14:50, 26 March 2013 (UTC)

See COM:UNSUPPORTED and its companion bug bugzilla:42725 − all formats there have been discussed before (I can try to dig the Village Pump discussions if needed).

I think there is a strong case for Raw image format (DNG) − bugzilla:19153 ; and I suppose Wikisource folks might be super interested in a ePub format − better check with them first if it is still needed.

Jean-Fred (talk) 14:56, 26 March 2013 (UTC)

Ah, I misread your post − I thought you meant a catch all entry here or on bugzilla, not for the GSOC. Sory for the confusion. Jean-Fred (talk) 10:48, 29 March 2013 (UTC)

VP8 now patent encumbered

Press release

Now Google has licensed for MPEG LA patents for their use in VP8 it's no longer free in the sense of being unencumbered by patents. It's still royalty free, though the precise license terms for sublicensees are unavailable: [1]. But that's the same as h.264 which is free for non-commercial use, but not used here because of patents. It may be subject to further licensing requirements, or even be banned, as Nokia are suing HTC over VP8 in Europe:[2][3].

The question is does anything need to be done about this? I would prefer it if the policy were able to support patent encumbered but free formats, especially h.264. But if that's not possible then should the use of VP8 be re-examined? --JohnBlackburne (talk) 20:19, 7 April 2013 (UTC)

It seems that encumbrance hasn't been confirmed yet? Check w:JPEG#Patent_issues. If you have FUD, you can keep the originals and upload also Theora versions.

Free for noncommercial use is not enough.

--AVRS (talk) 09:07, 8 April 2013 (UTC)

At least we should wait until "We anticipate having the terms of our sublicense ready in the next few weeks. When those terms are ready we will blog about them here, so watch this space." [Quote from 1] --McZusatz (talk) 18:22, 8 April 2013 (UTC)

Here's what looks like a draft agreement: [4]. Not sure when it went up as it's undated and I've just noticed it. There's also a FAQ [5]. Quite interesting and unlike typical open source licenses.--JohnBlackburne (talk) 22:40, 2 May 2013 (UTC)
