Today, Wikimedia and Mozilla announced a grant provided by the Mozilla Corporation towards maturing the support of Ogg in the Firefox Web browser. I’m happy to have helped in making the proposal become concrete and now we have the following three Xiph developers working on it:
- Viktor Gal – the maintainer of liboggplay
- Conrad Parker – the key developer of multiple Ogg support libraries, in particular liboggz
- Tim Terriberry – the key developer of Ogg Theora
Viktor will work towards stabilising the current Ogg Theora support in Firefox, Conrad will work towards Ogg network seeking, language selection and improved library support, and Tim will include the new Thusnelda Theora encoder improvements into Theora mainstream.
Looking forward to awesome Firefox video technology!
UPDATE – Other posts on this topic:
During the LCA 2009 Multimedia Miniconf, I gave a talk on video accessibility. Videos have been recorded, but haven’t been published yet. But here are the talk slides:
I basically gave a very brief summary of my analysis of the state of video accessibility online and what should be done. More information can be found on the Mozilla wiki.
The recommendation is to support the most basic and possibly the most widely online used of all subtitle/captioning formats first: srt. This will help us explore how to relate to out-of-band subtitles for a HTML5 video tag – a proposal of which has been made to the WHATWG and is presented in the slides. It will also help us create Ogg files with embedded subtitles – a means of encapsulation has been proposed in the Xiph wiki.
Once we have experience with these, we should move to a richer format that will also allow the creation of other time-aligned text formats, such as ticker text, annotations, karaoke, or lyrics.
Further, there is non-text accessibility data for videos, e.g. sign language recordings or audio annotations. These can also be multiplexed into Ogg through creating secondary video and audio tracks.
Overall, we aim to handle all such accessibility data in a standard way in the Web browser to achieve a uniform experience with text for video and a uniform approach to automating the handling of text for video. The aim is:
- to have a default styling of time-aligned text categories,
- to allow styling override of time-aligned through CSS,
- to allow the author of a Web page with video to serve a multitude of time-aligned text categories and turn on ones of his/her choice,
- to automatically use the default language and accessibility settings of a Web browser to request appropriate time-aligned text tracks,
- to allow the consumer of a Web page with video to manually select time-aligned text tracks of his/her choice, and
- to do all of this in the same way for out-of-band and in-line time-aligned text.
At the moment, none of this is properly implemented. But we are working on a liboggtext library and are furher discussing how to include out-of-band text with the video in the Webpage – e.g. should it go into the Webpage DOM or in a separate browsing context.

I spent the last few days doing some nice research for Vquence, where I was able to watch lots of videos on YouTube. Fun job this is! The full article is on the Vquence metrics blog.

Enjoy! And let me know in the comments if you know of any other video ad released in 2008 in the same ballpark number of views that is an actual tv-style commercial.
NOTE: I just had to change the list, because the SoBe Lifewater Super Bowl ad of 2008 actually came out ahead. It’s difficult to discover an ad that has neither ad nor commercial in its annotations!
