问题 At first, I'd like to ask that question. I can not load metadata without any other video content. preload = "metadata" is not working. I test on Win Chrome and don't know how it works on Safari/FF/IE/Opera. Thus I can't load six and more video clips fast. Chrome may keep only six opened connections at similar port/protocol/domain. And if I load more than six videos then last videos does not start load while first six videos fully complete loading. Does jsfiddle need? I can create but I think

问题 I have the Divx plugin downloaded (i think) the html files play in all my other browers but chrome. Instead, all that shows up in chrome is a black box with the words Divx in them. Why? Here is my HTML5 code: <div class = "video-js-box"> <video class = "video-js" width = "675" height = "380" controls> <source src = "/videos/videofiles/Reversing_a_Track.mp4" type = 'video/mp4; codecs="avc1.42E01E, mp4a.40.2"';/> <source src = "/videos/videofiles/Reversing_a_Track.ogg" type = 'video/ogg; codecs

问题 EXPLANATION: A customer of mine wants to have a background video running on his responsive website. However he would also like to remove it for tablet/mobile users.
