Module mediamtx 

Live-view gateway integration: registers a camera’s stream as a MediaMTX path (server-side, credentials never exposed to the browser) and returns HLS / WebRTC / RTSP playback URLs.

Structs

LiveUrls

Functions

ensure_live

Ensure a MediaMTX path exists for this camera and return its playback URLs. request_host is the Host header of the originating request, used to make loopback stream URLs reachable by the client.

set_webrtc_ice_servers

Program MediaMTX’s WebRTC ICE servers (STUN/TURN) so it gathers reachable candidates for remote viewing — needed for symmetric-NAT traversal. ice is a MediaMTX webrtcICEServers2 array ([{"url":..,"username"?:..,"password"?:..}]). Patches the RUNNING MediaMTX over its API (no restart).

transcode_codec_args

FFmpeg encoder args for the live preview transcode, selected by HELDAR_LIVE_TRANSCODE_ENGINE. software uses libx264 (CPU); vaapi offloads to an Intel/AMD render node; nvenc to an NVIDIA GPU. An unknown engine warns and falls back to software so a typo never breaks live preview.
