Trying to play HTML5 video in Safari but getting a blank video screen? Possibly with 0:00 second video length?
I posted the solution over on SO but basically this head scratcher can be solved by using a full URL for the <video>’s src attribute. If you don’t, Safari doesn’t even try to fetch the video.
I think this bug is only present in very specific versions of Safari (possibly just 5.0.5).
