I now this question is subjective. Hope it won't get closed because frankly, I cannot find any other source for this informations (including video.js docs). So I try...
I want to use video.js, I need a simple background video. I know there are simple css ways for this, but I also need to ensure the better playback possible, and I was wondering: does video.js help on this? Does it ensures some kind of optimised playback, don't know, by checking initial buffering or the like?
And if yes, does it have any problem with css ways of getting it fullscreen?
