The Media Support library (resipmedia)

resipmedia holds media code shared by recon and its media stacks.

recon requires it, so it is always built along with recon.

Contents

• sdpcontainer::Sdp : A structured model of an SDP session description, with sdpcontainer::SdpMediaLine, sdpcontainer::SdpCodec, sdpcontainer::SdpCandidate and sdpcontainer::SdpCandidatePair. Its media lines cover what recon negotiates beyond plain RTP, such as SRTP crypto attributes, DTLS fingerprints, transport capabilities and ICE candidates. SdpHelper builds an sdpcontainer::Sdp from a resip::SdpContents.
• resip::RTPPortManager : Hands out RTP ports (even numbers, with RTCP on the next port up) from a configured range.
• media/samples : Sample audio (music, and playback and record prompts) as headers of raw 8 kHz, 16-bit samples, which testUA and reConServer load into recon's media cache.

Optional Components

• media/gstreamer (CMake option USE_GSTREAMER) : GStreamer helpers used by recon's GStreamer media stack, in the resipgst namespace.
• media/kurento (CMake option USE_KURENTO) : A client for the Kurento media server's JSON-RPC API over WebSockets, in the kurento namespace, used by recon's Kurento media stack.
