A maximize button in the video controls that maximize the browser and zoom in on the video would automatically work with dom/js generated subtitles and other overlays. And require no standard updates.

I think some kind of miximize button is needed – users expects it and manually zooming and scrolling is a pain.

Hi! Turns out that a lot of that overhead comes from Mozilla’s drawing, not from the codec directly. And we continue to make improvements there in each release.

Man, that is cool!

I’m wondering if there is a way to use that to offer several different videos/clips in the same player instead of loading 5 (or more) different pages to view each video that may be offered?

Or perhaps the individual videos could be merged into one but divided into chapters with each stopping after they play out?

Of course it would probably be wise to keep the length of the videos somewhat short.
I like using autobuffer, but it seems to put a serious drag on my whole system.
My new trick is to add diversionary text while the video loads. :)

I’d appreciate any feedback on how to accomplish what I mentioned above since I’m not a developer by nature.
I just play one on TV.

I’m a huge fan of open standard and I really think the video tag is great in theory but the current Firefox implementation is extremely CPU hungry. It uses 35% of the CPU in not looking at zoomed video and 65% of the CPU if I zoomed in the video to fill my screen (Core 2 Duo 1.86Ghz).

I do hope that GPU acceleration of the Theora codec will be supported soon as the video tag is currently no better than Flash in performance terms.

With Ubiquity and a little patience, you can have machine translation of subtitles.

I’m not sure why running the whole page through Google Translate doesn’t work, or using Ubiquity’s edit and save commands on the subtitles. Any ideas on how to make that work?

Awesome BBC demo!

The subtitles trick opens for user generated translations of on-line videos. The same trick can be used for hot links in videos, both fore navigation in video and to related websites / videos – very useful!

But it make me wonder hove to make it work with maximizing of videos. The standard forbid script controlled maximization so the browser must ‘magicaly’ know what to maximize with the video.

One possibility is to add a style on divs telling the browser they are maximizable so if some element inside them is maximized the div with all it’s contents should be maximized instead – with all magical scaling it takes. But thats right now a standards question rather then a browser issue :-(

BTW. The ubuntu ‘standard’ build of firefox 3.5 for ubuntu 9.04 do not support maximization of videos yet – that make the free formats less useful (in an important sens) then the formats that use the old plug-in. But I guess it’s work in progress.

Sadly, their new HTML5 video controller’s volume slider no longer goes to 11. I hope they fix that before release.
