# .env.example — Runtime config for the studio app
# Author: Dr Hamid MADANI <drmdh@msn.com>
#
# Copy this to .env (loaded by ecosystem.config.cjs and Next.js) :
#   cp .env.example .env
#
# .env is gitignored.
#
# NB: Next.js inlines NEXT_PUBLIC_* vars at BUILD time (legacy fallback).
# The STUDIO_* keys below are read at RUNTIME by the server-component wrapper
# (app/page.tsx) via @mostajs/config — no rebuild required when you edit them,
# just `pm2 restart media-studio` (or relaunch `npm start`).

NODE_ENV=production
PORT=4499

# ── Persistence ────────────────────────────────────────────────────────────
# SQLite database for projects (relative to cwd).
# Set DB_DIALECT=postgres + SGBD_URI to use Postgres instead.
DB_DIALECT=sqlite
SGBD_URI=./data/media-studio.db
DB_SCHEMA_STRATEGY=update

# ── Public URL ─────────────────────────────────────────────────────────────
# Match this to https://${DEPLOY_DOMAIN}/ from .env.deploy.
NEXTAUTH_URL=https://media.example.com

# ── @mostajs/config profile (optional) ────────────────────────────────────
# Active profile : keys prefixed with ${MOSTA_ENV}_ override the plain keys.
# Example : MOSTA_ENV=DEV → DEV_STUDIO_AUDIO_STORAGE wins over STUDIO_AUDIO_STORAGE.
# MOSTA_ENV=PROD

# ── Studio runtime defaults (read by app/page.tsx via @mostajs/config) ────
# Recording mode at first load : 'screen-record' (default) | 'audio-only'
STUDIO_RECORDING_MODE=screen-record

# Output format default : 'mp4' | 'webm' | 'gif'
STUDIO_OUTPUT_FORMAT=mp4

# Section 3 (Audio & video sources) defaults
STUDIO_MIC_ENABLED=true
STUDIO_WEBCAM_ENABLED=true
STUDIO_SYSTEM_AUDIO_ENABLED=true

# Section 4 (Audio separate) defaults
STUDIO_RECORD_AUDIO_SEPARATELY=false

# Storage strategy : memory | indexeddb | filesystem | server
STUDIO_AUDIO_STORAGE=memory

# Endpoint that receives audio chunks when storage=server.
STUDIO_AUDIO_SERVER_URL=/api/record/audio

# ── Section 5 (Video storage — v1.11.9+) ───────────────────────────
# Storage strategy for the main video chunks :
#   indexeddb (default, crash-safe, RAM constante)
#   memory    (legacy <=1.11.8 — RAM linéaire ~60 MB/min en 1080p)
#   filesystem (Chrome/Edge — picker, disque local)
#   server     (POST chunks à STUDIO_VIDEO_SERVER_URL)
STUDIO_VIDEO_STORAGE=indexeddb

# Endpoint that receives video chunks when storage=server.
STUDIO_VIDEO_SERVER_URL=/api/record/video

# v1.11.10 — vraie séparation audio/vidéo
# Si true : le record vidéo n'embed PAS l'audio (track audio retirée).
# L'audio est forcément capturé dans un fichier séparé (force STUDIO_RECORD_AUDIO_SEPARATELY=true côté UI).
# Use case : montage pro / cleanup audio indépendant.
STUDIO_VIDEO_ONLY=false

# ── v1.11.22 — Publish to YouTube (optionnel) ────────────────────
# OAuth2 client ID Google pour upload direct depuis le navigateur.
# Setup :
#   1. https://console.cloud.google.com → nouveau projet
#   2. Activer YouTube Data API v3
#   3. Credentials → OAuth client ID → Web application
#   4. Authorized JavaScript origins : http://localhost:4499 + ton domaine prod
#   5. Coller le client ID ici (NEXT_PUBLIC_ pour exposition browser)
# Si vide, le bouton "Publish to YouTube" sera désactivé avec tooltip.
NEXT_PUBLIC_STUDIO_YOUTUBE_CLIENT_ID=

# ── v1.12.0 — Multi-camera : caméra par défaut (optionnel) ───────
# Le studio détecte toutes les caméras (videoinput) au runtime et propose un
# <select> superposé sur la preview pour switcher live (sans interrompre le
# record). Pour pré-sélectionner une caméra par défaut au lancement :
#
#   STUDIO_CAMERA_DEVICE_ID  = ID stable retourné par enumerateDevices()
#                              Ouvrir DevTools console et taper :
#                              navigator.mediaDevices.enumerateDevices()
#                              puis copier le deviceId voulu.
#                              ATTENTION : peut changer après reset privacy.
#
#   STUDIO_CAMERA_LABEL_HINT = fragment du label, case-insensitive (plus robuste).
#                              Ex : 'Logitech', 'OBS', 'USB'. Le 1er match gagne.
#
# Si les deux sont définis, DEVICE_ID a priorité, LABEL_HINT sert de fallback.
STUDIO_CAMERA_DEVICE_ID=
STUDIO_CAMERA_LABEL_HINT=

# ── v1.11.24 — Logo / Signature watermark (optionnel) ────────────
# Logo appliqué en watermark sur l'export final (overlay ffmpeg).
# Le fichier doit être servi côté Next.js — placer sous public/ puis URL absolue
# ou relative (ex: /logo.png). User peut override dans le sidebar editor.
STUDIO_LOGO_URL=/logo.png
STUDIO_LOGO_POSITION=top-right          # top-right | top-left | bottom-right | bottom-left
STUDIO_LOGO_SIZE_PCT=10                 # 1..50 (% largeur vidéo)
STUDIO_LOGO_OPACITY=0.85                # 0..1
STUDIO_LOGO_MARGIN_PCT=2                # 0..20 (% marge depuis les bords)

# ── Legacy NEXT_PUBLIC_* fallback (build-time, kept for back-compat) ──────
# Used only if the server wrapper isn't in place or the corresponding
# STUDIO_* key above is missing. Inlined into the bundle at `npm run build`.
NEXT_PUBLIC_RECORDING_MODE_DEFAULT=screen-record

# Audio capture toggles (section 3) defaults.
NEXT_PUBLIC_MIC_ENABLED_DEFAULT=true
NEXT_PUBLIC_WEBCAM_ENABLED_DEFAULT=true
NEXT_PUBLIC_SYSTEM_AUDIO_ENABLED_DEFAULT=true

# ── Audio separate recording (section 4) ───────────────────────────────────
# Save the mixed audio as a separate file in addition to the video record.
NEXT_PUBLIC_RECORD_AUDIO_SEPARATELY_DEFAULT=false

# Storage strategy for the separate audio chunks :
#   memory      — RAM, blob at the end (default, simple)
#   indexeddb   — IndexedDB, crash-safe, all browsers
#   filesystem  — File System Access API (Chrome/Edge only)
#   server      — POST chunks to NEXT_PUBLIC_AUDIO_SERVER_URL
NEXT_PUBLIC_AUDIO_STORAGE_DEFAULT=memory

# Endpoint that receives audio chunks when storage=server.
# Provided by examples/studio-app/app/api/record/audio/route.ts.
NEXT_PUBLIC_AUDIO_SERVER_URL=/api/record/audio

# ── Output format default (section 1) ──────────────────────────────────────
# 'mp4' (default) | 'webm' | 'gif'
NEXT_PUBLIC_OUTPUT_FORMAT_DEFAULT=mp4
