Setting the service up on a new host took 20 to 30 minutes, spent almost entirely in the Debian ffmpeg dependency chain: several hundred packages of X11 and desktop libraries that dpkg unpacks and configures file by file onto an SD card. That cost is paid again on every fresh machine and turned moving the service into a half-hour commitment rather than a routine step. Prebuilt binaries remove the package manager from the build entirely. A cold build with nothing cached now finishes in about four minutes on Pi hardware, verified end to end including audio transcoding. Pinning the dependency versions is unrelated to build speed. It prevents a rebuild months from now from silently resolving versions other than those the running container was tested with.
