It's recommended to use a static macOS build of FFmpeg, such as [Zeranoe's Builds](https://ffmpeg.zeranoe.com/builds/macos64/static/). There is a build phase script that will download this for you.
At the time of writing, please use [ffmpeg-4.2.1-macos64-static.zip](https://ffmpeg.zeranoe.com/builds/macos64/static/ffmpeg-4.2.1-macos64-static.zip).
Does the console inside Xcode show `Error Domain=NSPOSIXErrorDomain Code=13 "Permission denied"`? If so, Jellyfin may not have copied out correctly. Please let me know.
Does the console show a `Failed to bind to address` or `database locked` message? You may already have a copy of Jellyfin running on your computer. This can happen if you did not shutdown a separate Jellyfin install, or if you clicked on "Stop" inside Xcode. Use Activity Monitor to find and quit any open Jellyfin process.
This wrapper lets Jellyfin launch the Web UI automatically. If you want to change this, click the icon in the Menu Bar, and choose preferences. You can always use the menu icon to launch the Web UI.
