👁️ S2-Vision-Projection: Secure Vision Cast#

Welcome to the S2 Vision Projection. Operating as a smart switchboard, this tool first acts as a Protocol Sniffer (协议嗅探器) to discover existing mainstream wireless projection capabilities (Apple AirPlay, Google Cast, Miracast). If none are preferred or found, it falls back to the reliable S2 Native Secure Push.

🧬 Core Modes / 核心模式#

1. Environment Sniffer (全频段嗅探): Scans a target IP (or subnet) for open casting ports (e.g., 7000 for AirPlay, 8009 for Cast). / 扫描目标设备支持的主流无线投屏协议。
2. UPnP/DLNA Cast: Native DLNA routing for Smart TVs. / 针对传统智能电视的 DLNA 调度。
3. Secure Snapshot Push (S2 兜底): Encrypted, ephemeral frame push to S2 display nodes. / 绝对可靠的 S2 加密快照阅后即焚推送。

🤖 Instructions for AI Agents (CRITICAL)#

Prerequisite: export S2_PRIVACY_CONSENT=1 and S2_VISION_TOKEN

Step 1: Sniff the Target Display / 步骤 1：嗅探目标显示器 ALWAYS run this first to respect user's existing hardware ecosystem. / 永远优先运行此步骤以尊重用户现有的硬件生态。

bash

python3 vision_cast.py --mode sniff --target-ip 192.168.1.55

Step 2: Act on Sniff Results / 步骤 2：根据嗅探结果决策
Ask the user if they want to use the detected native protocol (e.g., AirPlay). If they agree, or if none are found, use Step 3.

Step 3: Execute Projection / 步骤 3：执行投屏
Bash

# S2 Fallback Push
python3 vision_cast.py --mode snapshot_push --target-ip 192.168.1.55 --payload "/tmp/s2_alert.jpg"
