Subject: [PATCH] feat: add WHIP-RTSP support for multi-platform streaming

- Introduced WHIP-RTSP as a new source option in Source.js.
- Enhanced Restreamer to handle RTSP relay configuration and address parsing.
- Updated WebRTCRoom to allow selection between direct and RTSP relay modes.
- Implemented WHIPPublications component for managing multiple WHIP destinations.
- Added internal RTSP relay configuration in Settings.js.
- Improved handling of WHEP and WHIP streams, including error logging and state management.

+## Parte 8 — Panel "Publicaciones" (re-streaming a redes sociales)
+
+### 8.1 Concepto general
+
+El usuario transmite **una sola vez desde OBS** hacia el Core (WHIP). El Core re-emite el stream a **todas las plataformas configuradas** en paralelo (YouTube, Twitch, Facebook, TikTok, etc.). Cada destino es un **proceso FFmpeg independiente** que lee del relay RTSP interno.
+
+```
+OBS ──WHIP──► Core RTSP relay :8554
+                      ├──► proceso "YouTube"   → rtmp://a.rtmp.youtube.com/live2/<key>
+                      ├──► proceso "Twitch"    → rtmp://live.twitch.tv/app/<key>
+                      ├──► proceso "Facebook"  → rtmps://live-api-s.facebook.com:443/rtmp/<key>
+                      └──► proceso "TikTok"    → rtmp://...
+```
+
+Cada proceso se crea con `POST /api/v3/process` y puede iniciarse/detenerse individualmente.
+
+---
+
+### 8.2 ⚠️ Limitación crítica de audio — Opus → AAC obligatorio
+
+OBS envía audio **Opus** (48 kHz, estéreo) via WHIP. El protocolo **RTMP/FLV** (que usan YouTube, Twitch, Facebook y TikTok) **no soporta Opus**; solo acepta **AAC** o MP3.
+
+Por lo tanto, en todos los procesos de publicación a redes sociales:
+- **Video**: `-c:v copy` ✅ — H264 pasa sin recodificación
+- **Audio**: `-c:a aac -b:a 128k` ✅ — Opus se transcodifica a AAC en tiempo real
+- **❌ `-c:a copy` está PROHIBIDO** para salidas RTMP — el stream llegaría corrupto o mudo
+
+El FFmpeg interno del Core ejecuta el proceso equivalente a:
+```bash
+ffmpeg -rtsp_transport tcp \
+       -i rtsp://127.0.0.1:8554/live/<stream_key> \
+       -c:v copy \
+       -c:a aac -b:a 128k \
+       -f flv \
+       rtmp://a.rtmp.youtube.com/live2/<youtube_key>

+| `Codec not found: aac` | FFmpeg sin soporte AAC (raro) | Imagen Docker correcta |
+| `Protocol not found: rtmps` | FFmpeg sin TLS | Solo aplica a Facebook/Instagram — usar imagen con OpenSSL |
+| `Invalid data found when processing input` | OBS no está transmitiendo | Arrancar OBS primero, luego iniciar procesos |
+| `Connection reset by peer` | La plataforma cerró el stream (clave duplicada en otra sesión) | Cerrar otras sesiones activas |
+
+---
+
+### 8.10 Prerrequisito: relay RTSP habilitado
+
+El relay RTSP **debe estar activo** para que `{whip-rtsp}` funcione. Verificar antes de mostrar el panel de publicaciones:
+
+```js
+async function checkRTSPRelay() {
+  const { data } = await api.get('/api/v3/config')
+  const rtspAddress = data.config.whip?.rtsp_address ?? ''
+  return rtspAddress !== ''
+}
+```
+
+Si el relay no está configurado, mostrar aviso:
+```
+⚠️ El relay RTSP no está activo.
+Para publicar en múltiples plataformas simultáneamente, activá el relay RTSP:
+Configuración → WHIP Server → Puerto relay RTSP (ej: 8554)
+```
+
+Si `rtsp_address` está vacío el usuario puede usar un proceso con `{whip:name=X}` para publicar a **una sola plataforma** (sin relay RTSP); en ese caso los output options son los mismos.
