ScreenStream

Secure one‑tap screen & audio share via WebRTC/MJPEG/RTSP to browsers/players.

• RTSP - Server or client mode with H.265/H.264/AV1 video + OPUS/AAC/G.711 audio.

Global (WebRTC)
• End-to-end encrypted, password-protected peer-to-peer stream
• Shares screen, microphone, and device audio
• Viewers join with Stream ID + password in any WebRTC-enabled browser
• Requires Internet; signaling handled by public open source server
• Audio/video flows directly between devices - Bandwidth grows per viewer
