cuframes-rtsp-source — standalone bridge между RTSP/file и cuframes IPC. Декодирует на CUDA (nvdec), копирует D2D в pre-allocated pool (EXTERNAL ownership), публикует через cuframes. --realtime для pacing файлового ввода, --loop для зацикливания. Альтернатива FFmpeg-фильтра до v0.2 (filter требует patch FFmpeg, конфликтует с Frigate's bundled build). examples/sub_count — reference subscriber на raw C API: counts frames, trackit gaps, выходит clean при disconnect/timeout/SIGINT. test_stress (4 subscribers × 2000 frames @ 120fps) — PASS на RTX 5090. 0 torn frames у всех consumers (включая 2 slow с 5ms sleep). Smoke-проверено: testsrc 25fps → cuframes-rtsp-source → cuframes IPC → sub_count (отдельный процесс) → 200/200 frames, 0 gaps, avg_fps=25.2.
