Used this with my Roku to stream movies locally, and it worked OK for the most part, but on more than one occasion it had a hard time with larger video files, often causing audio sync issues, weird freezing, or subtitle failures. I tried both the Jellyfin app and the Emby app on Roku with similar results; not sure if it's Jellyfin or the Roku app.
I've since switched back to Plex which streams flawlessly on my local area network.
