Not in this particular scenario, used Chrome specifically to to cast from jellyfin. The option is there but it didn't work. I think it might actually work if I tried a few more times because I noticed it seems temperamental like that, but that's not really any good because I don't want to be asking nicely for casting and maybe getting it if it feels like it. I've also noticed that with jellyfin, if the source media is decent quality to begin with, it casts at much poorer quality than with emby and takes longer to eventually end up screen. Sounds like a transcoding problem but I wish I knew why exactly because the horsepower is there and it's handled with aplomb in emby. It works okay with the android app on the live tv function which is mostly SD anyway but it craps out after about every 10 minutes of watching.
