The first pipeline uses `nvh265dec` for NVIDIA hardware decoding. The second uses `avdec_h265` for software decoding and works on any system (AMD, Intel, or no dedicated GPU). Software decoding uses more CPU but requires no specific graphics card.

- **Quad stream**: one player cam per IP (4 IPs total, one webcam each).
- **Main stream**: two player cams per IP (2 IPs total, two webcams each, ports `5001` and `5002`).
