I would like to display a users most recent video in the sidebar of their profile page. Is this possible? Can I use the gallery shortcode to do this in a text widget? What I want to do is place the video itself in the sidebar not just the video icon, i want it to be able to play in the sidebar.
Yes it can possible but will require some custom code. You can contact us -> https://rtcamp.com/contact/ for any rtMedia related customization work.
