New description:
Modern browsers are now natively supporting the embedding of video using
the <video> tag. A number of formats are now acceptable, depending on the
browser and OS. E.g. Firefox 3.5 only supports ogg, Safari 4 supports
h.264 (possibly others?), Chrome supports everything (ships with ffmpeg).
IE8 doesn't support the video tag at all, future IEs are probably unlikely
to. Which leaves a slightly messy situation, with two approaches:
1) In javascript, determine the browser's video and codec capabilities,
and write HTML pointing to the appropriate source (ogv, mp4, or fallback
to flv)
2) Use the html5 'source' attribute to specify multiple possibilities, and
let the browser decide which one it can use.
In both cases, at least two video formats will be needed on the server:
ogv and (probably) mpeg4. Transcoding will need to handle make both of
these.
Also in both cases, a fallback will be required - the easiest for users is
the previous default standard for web video - Flash (which we already
support with Flowplayer).
