Hi Martin, Andreas and Bernd,

We at the W3C Web & TV Interest Group are very much enjoying the fine work you published studying HTML5 video. I think this is a great contribution to improving HTML5 as a video platform. HTML5 just went final last week [HTML5] and there is need for both implementation improvement and further extensions.

As Silvia suggests below, there are some additional ways you can directly apply your findings for greatest effect:

1. For the implementation bugs in sections 1 - 3:

A. You could file bugs with each browser to get direct attention. I think the following are good links, but others may have other suggestions:
- https://support.google.com/chrome/answer/95315?hl=en

- https://connect.microsoft.com/IE

- https://www.apple.com/feedback/safari.html

- https://bugzilla.mozilla.org/enter_bug.cgi?format=guided


B. You could also contribute your tests to W3C to become W3C platform tests:
- http://testthewebforward.org


2. For your feature suggestion in section 4:

A. You can contribute feature requests to the W3C bug system: https://www.w3.org/Bugs/Public/enter_bug.cgi

B. You can contribute feature requests to WHATWG bug system: whatwg.org/newbug<http://whatwg.org/newbug>

3. You can also send your whole paper to the HTML WG list: public-html@w3.org<mailto:public-html@w3.org>

You’re also welcome to join the discussion here on the Web & TV IG list. The IG is a specification-writing group and we’ve worked on many media-related specifications that have been adopted into HTML5, DOM and other related specs. Your specific suggestions in section 4 seem more appropriate to submit directly to the HTML WG.

We welcome you to participate in the W3C on these and any future Web issues!

Thanks,
Mark Vickers
Web & TV IG co-chair

BTW: the audio data of a video element can very well be accessed using the web audio api. You might want to do some new experiments with that.

Also, may I suggest sending this assessment to the HTML WG list and/or the WHATWG list such that the implementers will actually see your results? I don't believe they would be subscribed to this mailing list.

Best Regards,
Silvia.

Nice to get an updated state of implementations. I did one 5 years ago in my "definitive guide to html5" book. As I was writing the book and came avoids differences in implementations, I registered bugs on the browsers (at least those that had public bug trackers). Many things improved since. Can I suggest you register bugs on the respective browsers, too? That would really help the community!

Best Regards,
Silvia.

Hello all,

It was good to see so many of you at our TPAC meeting last week.

Here is something I thought should be shared - a technical paper on web
video by three German researchers. It's an independent assessment of
HTML5 video support focussing on event mechanisms and seeking accuracy:

"A Comparative Evaluation of Current HTML5 Web Video Implementations"
http://www.ronpub.com/publications/OJWT-v1i2n01_Hoernig.pdf


It's good to see a peer-reviewed openly-available academic paper on this
subject and I hope there will be more, leading to greater shared knowledge.

With regards,
Daniel Davis
W3C
