In Search of: Universal Video Format

Question

I'm playing whack-a-mole trying to make an embedded video file work on all major browsers.

It's just a Quicktime h.264 .mov and .m4v file but if I use it doesn't work in IE, and if I use the Quicktime JS Prototype code it doesn't work in Firefox. Of course .flv won't work with IOS.

Is there a format/method of embedding that works on all major current browsers "out of the box"?

Answer 1

I woud use H.264 codec in MPEG-4 (MP4) container.
