Safari 5.0.5 won’t play HTML5 video

2012.03.30 | HTML5, Video, Web Development | ,

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).
