Media Protocol
Media protocols include SIP, RTSP, and RTMP streaming, plus WebRTC PeerConnection and application-level orchestration. The protocol stack is ESP Media Protocols. Applications use these protocols through esp_sip_service, esp_rtsp_service, and esp_rtmp_service: they link capture and playback and do not forward frames. Media service examples are sip_cli, rtsp_cli, rtsp_push, and rtmp_cli in Multimedia Examples. Examples that call the protocol stack directly are rtsp_demo / rtmp_demo in ESP-WebRTC Real-Time Communication Solution.
