HTML5 <video> with the OGG Theora codec
Flash
Something else (discussed below)
I agree with cician idea.
Or Phoronix could simply put both videos. The people that don't have flash player won't see that version, and the people's browsers that doesn't support the html 5 <video> tag, they won't see it.
Or simple put the video with html 5 <video> and a link to youtube or dailymotion (which supports both) for the flash video.
I vote Flash. Because it just works.
This is a no-brainer, honestly.Code:<video src="whatever"><object data="old crappy flash video"></video>
Who gives a shit about IE? This is a Linux forum.
