MediaCapabilities Hardware Matrix W3C DecodingInfo API

Direct query of the client's GPU media engine. Verifies whether high-resolution video streams are decoded via dedicated silicon (NVDEC, Intel QuickSync, Apple VideoToolbox) or software fallback.

WebRTC In-Memory Loopback Pipeline IDLE

Instantiates two local RTCPeerConnection endpoints (`pc_sender` ↔ `pc_receiver`), generates a synthetic Canvas video track, exchanges SDP offer/answer with ICE candidates, and measures RTT via getStats().

Ready to initialize

[System] WebRTC loopback module loaded. Ready to probe local SDP negotiation.
