I have a HTML5 video tag on my website, every browser is playing it correctly. The problem is when I'm on Opera Mini and when I press play button - video is not starting and I'm getting info: This file can not be downloaded. When I press play second time it's starting correctly.
<video preload="none" id="videoAbout" controls poster="/images/video/video.jpg">
<source src="/video/openform-final.webm" type="video/webm">
<source src="/video/openform-final.ogv" type="video/ogg">
<source src="/video/openform-final.mp4" type="video/mp4">
Video is not supported.
</video>
Opera Mini does not support html5 so your video tag won't work
Which is why it won't support the video tag.
