Some Months ago, i discover the function of Plex Pre-Roll, which is only for movies.
I was wondering if it was posible to use the Plex Pre-Roll in Yatse? Like… when you play or cast a movie to a TV, Kodi, celphone, etc…
P.S.
When i use the app Plex in a TV or in a browser it shows the Pre-roll like a diferent video. After the Pre-Roll ends it start charging the buffer of the movie.
No idea what it is 
Do you have any direct link for doc about it?
Here is the oficial info of Plex Pre-Roll (Plex has Marked this with the name “Extra”)

And Here is a little video of the pre-roll recorded from the Plex Web App

Ok so that’s not that easy as currently local player is external to Yatse and most don’t support playlists to send both the media and pre roll before.
