Ohne -re liest ffmpeg den PCM-Stream von librespot so schnell wie möglich. librespot meldet die Position dann zu schnell an Spotify, was dazu führt dass Tracks im Sekundentakt wechseln und Stop/Skip vom Handy nicht funktionieren. Mit -re wird der Input auf native Framerate gedrosselt (44100 Hz S16LE Stereo → ~176 kB/s), sodass Position korrekt gemeldet wird. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
