[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:

[Wikivideo-l] Most popular videos

So I just recently discovered that WMF is now publishing stats for media files.

So in terms of most popular videos, it seems to be mostly space and
porn. (This list is url of file minus the https://upload.wikimedia.org
part then a comma, then the number of downloads on 2015-07-25)

This comes from the top1000 csv zip files at
http://dumps.wikimedia.org/other/mediacounts/daily/2015/, using the
mediacounts.2015-07-25.v00.sorted_key17.csv file.

Anyways, thought it would be interesting to this list.

[Wikivideo-l] Interesting - Slashdot on H.265

http://yro.slashdot.org/story/15/07/26/0149234/hevc-advance-announces-h265-royalty-rates-raises-some-hackles

Dan Rayburn from Streaming Media advocates that "content owners band together and agree not to license from HEVC Advance" in the hope that "HEVC Advance will fail in the market and be forced to change strategy, or change their terms to be fair and reasonable." John Carmack, Oculus VR CTO, has cited the new patent license as a reason to end his efforts to encode VR video with H.265.

TMH RL changes

I think we all want to ditch TMH sooner than later, but i’ve had this patch to do some cleanup to it for a while now (1,5 year):

Clearly few people are capable of reviewing it to begin with, and worse I think there are plenty of people so scared of this code, that they’d rather keep it like it is, instead of risking to break production...

So should I abandon it ?

[Wikivideo-l] Debut of WEP mini-doc at Wikimania

FYI, thought folks might find this interesting -- there was a debut of a mini-documentary at Wikimania about Tec de Monterrey using Wikipedia in the classroom. It was very well done, and right after the talk, I helped the filmmaker get it from his MOV format onto Wikimedia Commons thanks to the new Schnittserver.


English and Spanish subtitles are available.

[Wikivideo-l] Wikimedia video community editing tools & infrastructure status

There were a fair number of folks interested in video chatting at Wikimania! A few quick updates:

* An experimental 'Schnittserver' ('Clip server') project has been in the works for a while with some funding from ze Germans; currently sitting at http://wikimedia.meltvideo.com/ (uses OAuth, has a temporary SSL cert, UI is very primitive!) It is currently usable already for converting MP4 etc source footage to WebM!

The Schnittserver can also do server-side rendering of projects using the 'melt' format such as those created with Kdenlive and Shotcut -- this allows uploading your original footage (usually in some sort of MP4/H.264 flavor) and sharing the editing project via WebM proxy clips, without generational loss on the final rendering.

Once rendered, your final WebM output can be published up to Commons.

I would love to see some more support for this project, including adding a better web front-end for managing projects/clips and even editing...


* Mozilla has an in-browser media editor thing called Popcorn.js; they're unfortunately reducing investment in the project, but there's some talk amon people working on it and on our end that Wikimedia might be interested in helping adapt it to work with the Schnittserver or some future replacement for it.

Unfortunately I missed the session with the person working on Popcorn.js, will have to catch up later on it!


* I'm very close to what I consider a 1.0 release of ogv.js, my JavaScript shim to play Ogg (and experimentally WebM) video and audio in Safari and MS IE/Edge without plugins.

Recently fixed some major sound sync bugs on slower devices, and am finishing up controls which will be used in the mobile view (when not using the full TimedMediaHandler / MwEmbedPlayer interface which we still have on the desktop).


A slightly older version of ogv.js is also running on https://ogvjs-testing.wmflabs.org/ with integration into TimedMediaHandler; I'll update those patches with my 1.0 release next week or so.


* Infrastructure issues:

I had a talk with Faidon about video requirements on the low-level infrastructure layer; there are some things we need to work on before we really push video:

- seeking/streaming a file with Range subsets causes requests to bypass the Varnish cache layer, potentially causing huge performance problems if there's a usage spike!

- very large files can't be sharded cleanly over multiple servers, which makes for further performance bottlenecks on popular files again

- VERY large files (>4G or so) can't be stored at all; which is a problem for high-quality uploads of things like long Wikimania talks!

For derivative transcodes, we can bypass some of these problems by chunking the output into multiple files of limited length and rigging up 'gapless playback', as can be done for HLS or MPEG-DASH-style live streaming. I'm pretty sure I can work out how to do this in the ogv.js player (for Safari and IE) as well as in the native <video> element playback for Chrome and Firefox via Media Source Extensions. Assuming it works with the standard DASH profile for WebM, this is something we can easily make work on Android as well using Google's ExoPlayer.

DASH playback will also make it easier to use adaptive source switching to handle limited bandwidth or CPU resources.

However we still need to be able to deal with source files which may be potentially quite large...


* List and phab projects!

As a reminder there's a wikivideo-l list: https://lists.wikimedia.org/mailman/listinfo/wikivideo-l

and a Wikimedia-Video project tag in phabricator: https://phabricator.wikimedia.org/tag/wikimedia-video/

Folks who are interested in pushing further work on video, please feel free to join up. There's a lot of potential awesomeness!

Slideshow feature

Hi Multimedia enthusiasts,

Today I added two galleries of my successful FP nominations to my user page. (Can I say again how much I like the gallery feature?) Anyway, on Commons there is this green button in the upper right corner of my user page that starts a slideshow when I click it. The slideshow is like MediaViewer with extra text info about each file, and I like it. A lot. Can we get that little green button to appear on pages on ENWP in addition to Commons? For example, currently the slideshow button is missing from my userpage when I view it on ENWP, and I think having that icon visible on other galleries and articles would be worth trying.

Thanks!

Pine

[Wikivideo-l] Popcorn Maker at Wikimania

Hi all,

If you are at Wikimania, please say hello to Michael Nolan, cc'd. Mike is currently interning at Mozilla and his focus is to help "white-label" Popcorn Maker, our browser-based video editor, so others can deploy it in their web apps. He's also a big free culture and access to knowledge advocate on his campus.

Mike is attending Wikimedia to understand potential use cases and to hopefully build a prototype showing how this could work on Commons.

If this sounds interesting, would encourage you to reach out: mnolan <at> mozilla.com. Mike will be attending the hackathon and most of the video-related conference sessions. Here is the repo where he's currently working: https://github.com/nolski/popcorn-editor

Some background: Popcorn Maker is something we have been working on for a few years at Mozilla. You can try it out here: http://popcorn.webmaker.org. We will be winding down Popcorn Maker as a Mozilla service over the next few months, but naturally as an open source project we are interested in seeing whether parts of Popcorn's source code can help solve problems for others.

Believe it or not, my motivation for helping to build Popcorn Maker stemmed from the 2010 era excitement around collaborative video editing on Wikimedia projects. I think that as far as media sequencing, remix and attribution goes, Popcorn is at least 80% of the way towards awesome and should be part of experiments on Labs & conversations on how the Wikimedia project should approach collaborative media production over the next few years. I wrote more on the opportunity here:


Post-Wikimania, would love to organize a call so we can plan further with interested folks.

Cheers!
Ben
