I am a developer working on a site that makes heavy use of video. The site navigation and video playback controls run together, so it's important for me to be able to have full control over the videos, however, the videos must be hosted on Vimeo. The information on Firefox support for H.264 is all over the map, though at this point, I am just assuming, for the sake of practicality, that Firefox doesn't support H.264 playback at all. If I can't find a good solution, we are simply going to draw the line at Firefox and not support the browser at all for this site. It would be nice for the site to work on Firefox, but we estimate that less than 6% of our viewers will be using the browser, so it won't be hard to just redirect them to a different browser. Is there any hack, any workaround, anything at all, that I can do to play H.264 video using just the good old standard <video> tag?
