Made this single container to build and deploy jellyfin to Samsung TVs.

Credits go to the following:

• https://github.com/jellyfin/jellyfin-tizen
• https://www.reddit.com/r/jellyfin/comments/s0438d/build_and_deploy_jellyfin_app_to_samsung_tizen/

• Docker
• Internet connection for the Docker containers

1. Enable developer mode on the TV (adapted from official tizen guide):
   • Turn on the TV
   • Go to the apps page
   • Press 12345 on the remote
   • Enable Developer mode in the dialog that pops up, and write the IP of the host running docker
   • Shut down and restart the TV as instructed by the information screen, re-enter the apps page
   • There should be (or could be, depending on the model) a big red text in the top bar saying Developer mode
   • Keep the TV on
2. Build the application

   docker build -t jellyfin .
   

   If it fails to execute expect.sh in the last step, you might need to download it again from here and overwrite the one in the directory from which you're building.
3. Deploy the application to the TV:
   • Run the container with the attached terminal

     docker run -it --rm jellyfin
     

   • Connect to TV with Device Manager from Tizen Studio. Or with sdb.

     sdb connect YOUR_TV_IP

   • Find your device ID using:

     sdb devices
     

     The device ID will be the last column, something like UE65NU7400.
   • Install package

     tizen install -n Jellyfin.wgt -t DEVICE_ID
