I need to see a thumbnail of my video on mobile. So far everything I found didn't work. This is the code i have now:
<video class="some_class" controls>
<source src="some/url/path.mp4" alt="some alt text" >
</video>
The things I tried is to add the preload="metadata"
and my frame to my video source #t=0.5
but those things didn't work.
It is not possible to use poster because I can't know witch picture the customer wants to use on a specific video.
The problem is very mobile specific due to the fact that the thumbnails works on all the other browsers, except the mobile ones.
