 #### Default - Development Jellyfin Server

Each time you create a new container you have to run though the whole setup again. There is also no ffmpeg, webclient or media preloaded. Use the `.NET Launch (nowebclient)` lunch config to start the server.

-> Keep in mind that as this has no web client you have to connect to it via an extenal client. This can be just another codespace container running the WebUI. vuejs does not work from the getgo as it does not support the setup steps.

 If you want to install a specific ffmpeg version, follow the comments embedded in the `.devcontainer/Dev - Server Ffmpeg/install.ffmpeg.sh` file.
 
 Use the `ghcs .NET Launch (nowebclient, ffmpeg)` launch config to run with the jellyfin-ffmpeg enabled.
