HTML5 Video

Browser support is very varied, Firefox only supports Ogg video (plus WebM in Firefox 4), Opera supports WebM and Ogg video but purports to play H.264 video if the user has the codec installed, Internet Explorer has only H.264 support built in, but Microsoft reversed a previous decision to exclude WebM (choosing to play WebM only if the user has installed the codec themselves) and Safari will play anything QuickTime can play, but on iOS this is no more than MPEG4 and H.264.
