Add video poster in media browser

When you upload images you get to see amazing thumbnails in the browser. This unfortunately isn't the case for videos. Could we somehow have this?

This is what we currently have:

One point worth bearing in mind is that a screenshot of the first frame of a video is usually useless as it's quite often blank. YouTube used to use a frame from the middle of the video (it lets you pick, now, I believe).

When you click on the thumbnail, the details open and you can see what's inside the video, so I don't feel the need for any selection of a 'good' preview image. I'd see it as a good enough enhancement if we just integrate the 'first view' instead the default icon; like in the screenshot attached. Even if it would be black, I can still see the title and if I want to know more, I'd click on it and have a closer look. Just my 2c so far

I like this, but it might be a pretty limited amount of hosts that can support it, so an initial patch, then test + survey would be good.

Imagick (and WP_Image_Editor_Imagick, to a limited extent) supports video formats, but the support varies based on availability and configuration of ffmpeg on the system.

Note that my concern from comment:2 still stands.

I wonder if core's ID3 library supports detecting the thumbnail if one is specified in the video file. Needs testing.
