From c693cab35cbe260684ee32bccac0911b87377290 Mon Sep 17 00:00:00 2001 From: Talon Date: Tue, 16 Jun 2026 02:12:50 +0200 Subject: [PATCH] fix(M2): wire vc_client's real voice plane through the C ABI, not just raw sockets test_m2_voice passed against raw BSD sockets, but vc_client::stream_start/stop, UDP binding, and capture/recv were still VC_ERR_NOT_IMPLEMENTED stubs -- meaning vccli and any GUI client still couldn't actually talk. Implements the real client-side UDP-binding handshake, media key derivation, capture->encode->seal-> send and recv->open->decode->playback paths, plus server-side StreamInfo broadcast so peers learn about each other's streams via sync_remote_streams(). Adds test_voice_client_abi (two real vc_client instances, not raw sockets) and vccli --voice/--mute/--text flags, manually verified live between two instances.
