Seekable video support in Plone 5.2?

The video is support in Plone is pretty limited.

I uploaded a MP4 file and the users are unable to skip or seek within the video - so, out-of-the-box a pretty useless functionality


Will help here?

I am also interested in this.

Are there any alternatives. Are there ways to host 'private' videos on vimeo or similar and somehow share theme only to users that has certain rights ?

Any way this could be combined with wildcard media ?
Is a Digital Asset management system an alternative ?

Range-support was added to plone.namedfile in
