[Wikivideo-l] Wikiconference USA session submission

FYI, this is the video-related submission for Wikiconference USA, October 9-11, 2015 in Washington DC. We plan on having part of the Sunday unconference day to work on next steps related to possibly working with Mozilla and Internet Archive to further a full editing system.

http://wikiconferenceusa.org/wiki/Submissions:2015/Video_in_Wikimedia:_Today_and_Tomorrow

Hope to see some interested folks from this list there in DC.

-Andrew

Alliance for Open Media: everybody but Apple now working on next-gen open codec

This may be of interest:

http://aomedia.org/press-release/alliance-to-deliver-next-generation-open-media-formats/

Amazon, Cisco, Google, Intel, Microsoft, Mozilla, and Netflix are pooling resources to work on hammering out a standard, royalty-free, next-gen open video codec.

Cisco and Mozilla had already started working together, combining ideas from Cisco's Thor codec and the Mozilla-sponsored Xiph's Daala codec, but getting them together with Google's VPx team is a big happy occasion... getting Intel and Microsoft on board means probably hardware support on x86_64 chips and support in Windows and MS Edge, while Amazon and Netflix pump a lot of video volume out both to browsers and devices, so should help push adoption by ARM SoC makers.

In other words, AWESOME SAUCE!

The only missing major player looks to be Apple... so we'll see if they eventually join on or if they double down on HEVC and we keep having to play JavaScript tricks. :P


I'm subscribing to their mailing list for updates; it may be worth looking into if we can partner in or at least follow along and support stuff on our end.

Paper about DBpedia Commons (RDFization of content metadata)

Hello,

Vaidya et al. have published a paper about the work they did to
extract content metadata from Commons description pages, using
existing and new DBpedia tools. This could be of interest to this list
as it relates to Structured data for Commons.

PDF: http://jens-lehmann.org/files/2015/iswc_dbpedia_commons.pdf

The paper is relatively short and reads easily. I've also written a
review for the Signpost's latest "Recent research" report:

https://en.wikipedia.org/wiki/Wikipedia:Wikipedia_Signpost/2015-08-26/Recent_research#.22DBpedia_Commons:_Structured_Multimedia_Metadata_from_the_Wikimedia_Commons.22

[Wikivideo-l] Prep work for WebM VP9 support

Just a quick note -- there's been some ongoing work in preparation for supporting WebM with the newer VP9 codec:

* fixing up our server configuration with updated ffmpeg & ffmpeg2theora packages
* fixing up the player to support VP9 as well as VP8
* adding support for producing WebM transcodes in VP9 in addition to VP8

Big thanks to a bunch of folks over on the ops side who have been helping with the packaging! We had to backport some packages to get VP9 working, and ffmpeg2theora needed some patches to work correctly in newer versions.


At some point in the coming weeks, the video transcoding servers will be re-imaged with an updated operating system (Ubuntu Trusty plus our custom packages). Once this is complete, uploaded WebM VP9 files should start producing Ogg Theora and WebM VP8 transcodes (currently you can upload them but they fail to work).

With TMH updates going out some time next week, playback of VP9 originals should also start working in Chrome and Firefox.

These updates also improve support of Opus audio files, both standalone in Ogg audio and in WebM videos.


Once we're satisfied everything works, we'll consider enabling production of VP9 transcodes. These will be about the same quality as VP8, but use only half the bandwidth. Later when we figure out how to rig up adaptive streaming, this'll mean bandwidth-constrained clients can bump up one resolution step in VP9 versus VP8...

One big warning -- VP9 encoding is 2-4x slower than VP8 encoding at the same resolution... so we'll have to investigate comparative CPU load and whether 1080p transcodes actually complete reliably before timeouts etc hit. This may be something we have to roll out later after more testing.

But even if it takes us time to get VP9 output working, having VP9 input functional will fix some existing files, make it easier to import from YouTube and other sources that are more aggressively using VP9, and generally makes us more future-proof.

Exif values retrieved incorrectly if they appear before IFD

Could someone clarify in the task what's the way ahead for 
https://phabricator.wikimedia.org/T97253 ?
Do we "just" wait for upstream and do nothing?

Thanks!

[Wikivideo-l] Mike Nolan's Mozilla Popcorn.js talk

Hi all,

This should be interesting to folks -- Popcorn.js, the highest profile open source video editing/assembly project that is web browser-based, was Mike Nolan's summer internship project at Mozilla. His video presentation is below.

Some of you may know he was at Wikimania in Mexico City and talked with a number of us on the status of video in Wikimedia. He gives a shout out to our efforts and the potential for Popcorn being part of the solution at the end of this talk.

Mike and I also recently met with the Internet Archive folks in SF and they're keen to keep working with us, and to look into funding for the three entities -- the Wikimedia movement, Mozilla and Internet Archive. 

-Andrew



Mike Nolan: "Going the Extra 10%: The Next Generation Video Editor on the Web"
Since the dawn of YouTube and smart phones, video content on the web has grown an immense amount. Once, where web pages were simple collections of long form text markup are now rich multi-media applications. The user's ability to store video content on the web has evolved along with many of the web standards today but even now in 2015, users are required to often times purchase expensive and bulky video editing applications with steep learning curves to edit existing content.

This talk goes over Mike Nolan's intern project to modify the Popcorn Maker project into it's own modular javascript library and create a python library for transcoding the Popcorn Maker editor json into a flat ".webm" video file.

Image alignment issues

This is the second article recently in which I've encountered unexpected behavior when trying to align images.

https://en.wikipedia.org/wiki/White-cheeked_starling

Am I missing something, or is there a bug that's resulting in images being misplaced?

Uploading from WikiEditor

Hi! I just posted my gadget from the hackathon on VPT on enwiki [0]. Anyone
should feel free to port the gadget (and its dependencies) to other wikis,
there shouldn't be any necessary code changes, unless you port it to Commons,
in which case you don't need the fancy bending-over-backwards-for-CentralAuth
code.

I won't be maintaining this, it's just a proof of concept for our future work
on proper, extension-y dialogs in editors, but I thought I'd share it with
early adopters.

[0] https://en.wikipedia.org/wiki/Wikipedia:Village_pump_%28technical%29#Upload_file_from_WikiEditor...to_Commons

Cheers all,

Going to land ogv.js into TimedMediaHandler if no one objects

I've done some more fixes to ogv.js to perform *much* smoother on slower machines by running the decoders in Web Worker threads. If there's no objection, I'm going to land ogv.js (and a number of smaller fixes for media playback) into TimedMediaHandler later today.

ogv.js is a JavaScript compatibility shim for Ogg and WebM video in Safari and IE/Edge which don't support free codecs natively. (IE/Edge on desktop can use native WebM components if you install them manually but still lack Ogg audio support.) This replaces the old Cortado Java applet that no longer works on most current computers.

Please feel free to help review and test! Live demo site https://ogvjs-testing.wmflabs.org/


MwEmbedSupport:
https://gerrit.wikimedia.org/r/#/c/227074 - fix fullscreen video in IE

TimedMediaHandler:
* https://gerrit.wikimedia.org/r/#/c/219398 - TMH transcode list ordering fix
https://gerrit.wikimedia.org/r/#/c/226999 - fix double-playback in IE/Edge with native webm installed
https://gerrit.wikimedia.org/r/#/c/227066 - fix the popup player on first open
https://gerrit.wikimedia.org/r/#/c/227155 - increase quality of Ogg Theora transcodes, add 240p with the old bandwidth of 360p

There's also my basic mobile integration, which requires some more work to support suitable controls:

[Wikivideo-l] Some Wikimania 2015 Videos available

I just posted this to the Wikimania list, but wanted to let video folks know as well:


Hi all, there are some Wikimania 2015 videos available now, guerrilla style:

As you may know, there was no central video recording of Wikimania sessions this year. But with my own camcorder and an iPhone 5, I was able to record 26 sessions at Wikimania of varying quality. You can visit them on this page. Any assistance to help annotate or expand on the chart is appreciated.


Also, for a glimpse of how arduous the video process can be, see:
