I am developing and webpage, where subpages are downloaded with pjax and dynamicly inserted into document. In few pages i have
<video> tag as below:
<video poster="img/slide_1.jpg" autoplay muted loop>
<source src="video/slide_1.mp4" type="video/mp4">
<source src="video/slide_1.webm" type="video/webm">
In Chrome and FF everything seems to work well. In IE (checked on v11) i get a box with dimensions of video but all filled with black.
I have tried turning off caching by adding query string parameter
?t= with some random value, but got no effect. Thought resposne HTTP codes are relevant, but no matter if i got 200, 206, or 304, browser behavior was totally random.
When I hit the URL in the browser (normal GET request) i found no errors.
Does anybody have a clue, how to cope with that?
