# Emby

Media server for movies, TV, and music.

- Web UI: http://localhost:8096  (HTTPS on 8920)
- Media folder: \`$MEDIA_PATH\` → mounted at /media
- App data: \`config/\` in this folder
- Edit the media path in \`.env\` (\`MEDIA_PATH=\`), then \`docker compose up -d\`.

## Manage
\`\`\`bash
cd $EMBY_DIR
docker compose up -d      # start
docker compose down       # stop
docker compose logs -f    # logs
docker compose pull && docker compose up -d   # update
\`\`\`

## Hardware transcoding
Uncomment the \`devices: [/dev/dri:/dev/dri]\` block in \`docker-compose.yml\`
once you've confirmed your Intel/AMD GPU exposes a render node, then restart.
