In Emby, I was able to use offline trailers by having a file named Trailer.mkv in the Specials directory. However this doesn’t work in Jellyfin. I also tried ‘%movie name% - trailer.mkv’ but that doesn’t work either. Is there a way to do offline trailers in Jellyfin or is this not a feature that is implemented?
First - Thank you for doing this test. It kept slipping my radar to try it.
Second - I think then that this is part of the Cinema Mode plug-in, which unfortunately we don’t have code for. Something would have to be started from scratch.
