Related to the discussion of size and bitrate of uploaded video discussions on wikivideo-l, I thought it would be nice to share the latest efforts on the TimedMediaHandler extension.
This extension will help make the size and bitrate choices less of an issue, and will just be a matter of uploading the highest quality version you can. The extension auto transcodes to a few different derivative formats.
Its best illustrated by features overview page: ( best viewed with Firefox 4 ) http://prototype.wikimedia.org/timedmedia/Main_Page
This extension standardises a lot of features of the mwEmbed player gadget, like pop-up gallery videos, temporal media fragments, timed text, iframe embed video sharing, html5 standard "video", "source" and "track" page output, etc.
The bottom clip illustrates a key feature of this extension with a real commons "media of the day" clip from a few days back. JJ Harrison uploaded a very nice, very encyclopaedic HD nature clip, but at 1920x1088 and 13mbs it fails to playback almost any time some tires to play it :( With this extension we get the 'right' resolution given the embed size, and have easy access to switch streams as you go into fullscreen if your computer / connection supports it.
There are still a few resource loader integration issues to work out before more widely sharing these efforts, but I thought I would share it on these list to get some early feedback.
I have filed a tracking bug https://bugzilla.wikimedia.org/show_bug.cgi?id=27699 to keep track of its progress toward deployment. If you file related related bugs or feature requests, you can tag them with that tracking bug.
Also got started on a mediawiki.org extension page: http://www.mediawiki.org/wiki/Extension:TimedMediaHandler
