Modern browsers are now natively supporting the embedding of video using
the <video> tag. Unfortunately the original plan to use ogg/theora for
this was dropped, and 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. This can either be flash
video or cortado. Cortado is nice in that it can use the existing ogg
stream to play the video, and is open. Flash is nice in that most browsers
have it (citation needed? What is the uptake of java vs flash?), but would
need a third video stream on the server (and is not open). The fallback
should be relatively easy to implement in the second case by including an
object tag inside the video tag - this will be ignored by browsers
supporting the video tag, but used by browsers not supporting it. Will
need to do some research about cortado/java vs flowplayer/flash, including
bandwidth and CPU issues.
