I have a full width background video with autoplay and loop propreties and works really good on desktop but in mobile video dont show and dont start... just show a black screen
I need to fix this for mobile, if that's not possible to put video working on mobile I can put a background image on mobile
<video autoplay loop muted autobuffer preload="auto" poster="poster.png" class="background-video">
<source src="video.webm" type='video/webm; codecs="vp8.0, vorbis"'>
<source src="video.ogv" type='video/ogg; codecs="theora, vorbis"'>
<source src="video.mp4" type='video/mp4; codecs="avc1.4D401E, mp4a.40.2"'>
</video>
The Autoplay tag on mobile is generally not supported - this is to avoid users incurring data transfer costs as video files are large and can eat into data limits.
The poster tag should work fine, however, as I think you noted in your last comment.
