After building you can start baresip like this: ``` $ baresip ``` The config files in $HOME/.baresip are automatically generated the first time you run baresip. ## Documentation The online documentation generated with doxygen is available in the main [website](http://creytiv.com/doxygen/baresip-dox/html/) ### Examples Configuration examples are available from the [examples](https://github.com/baresip/baresip/tree/master/docs/examples) directory. ## License The baresip project is using the 3-clause BSD license. ## Contributing Patches can be sent via Github [Pull-Requests](https://github.com/baresip/baresip/pulls) or to the RE devel [mailing-list](http://lists.creytiv.com/mailman/listinfo/re-devel). ## Design goals: * Minimalistic and modular VoIP client * SIP, SDP, RTP/RTCP, STUN/TURN/ICE * IPv4 and IPv6 support * RFC-compliancy * Robust, fast, low footprint * Portable C89 and C99 source code ## Modular Plugin Architecture: ``` aac Advanced Audio Coding (AAC) audio codec account Account loader alsa ALSA audio driver amr Adaptive Multi-Rate (AMR) audio codec aptx Audio Processing Technology codec (aptX) aubridge Audio bridge module audiounit AudioUnit audio driver for MacOSX/iOS aufile Audio module for using a WAV-file as audio input auloop Audio-loop test module ausine Audio sine wave input module avcapture Video source using iOS AVFoundation video capture avcodec Video codec using FFmpeg/libav libavcodec avformat Video source using FFmpeg/libav libavformat b2bua Back-to-Back User-Agent (B2BUA) module cairo Cairo video source codec2 Codec2 low bit rate speech codec cons UDP/TCP console UI driver contact Contacts module coreaudio Apple macOS Coreaudio driver ctrl_tcp TCP control interface using JSON payload debug_cmd Debug commands directfb DirectFB video display module dshow Windows DirectShow video source dtls_srtp DTLS-SRTP end-to-end encryption ebuacip EBU ACIP (Audio Contribution over IP) Profile echo Echo server module evdev Linux input driver fakevideo Fake video input/output driver g711 G.711 audio codec g722 G.722 audio codec g7221 G.722.1 audio codec g726 G.726 audio codec gsm GSM audio codec gst Gstreamer audio source gst_video Gstreamer video codec gtk GTK+ 2.0 UI gzrtp ZRTP module using GNU ZRTP C++ library httpd HTTP webserver UI-module i2s I2S (Inter-IC Sound) audio driver ice ICE protocol for NAT Traversal ilbc iLBC audio codec isac iSAC audio codec jack JACK Audio Connection Kit audio-driver l16 L16 audio codec menu Interactive menu mpa MPA Speech and Audio Codec mqtt MQTT (Message Queue Telemetry Transport) module mwi Message Waiting Indication natpmp NAT Port Mapping Protocol (NAT-PMP) module omx OpenMAX IL video display module opengl OpenGL video output opensles OpenSLES audio driver opus OPUS Interactive audio codec oss Open Sound System (OSS) audio driver pcp Port Control Protocol (PCP) module plc Packet Loss Concealment (PLC) using spandsp portaudio Portaudio driver pulse Pulseaudio driver presence Presence module qtcapture Apple QTCapture video source driver rtcpsummary RTCP summary module rst Radio streamer using mpg123 sdl Simple DirectMedia Layer 2.0 (SDL) video output driver selfview Video selfview module snapshot Save video-stream as PNG images sndfile Audio dumper using libsndfile sndio Audio driver for OpenBSD speex_pp Audio pre-processor using libspeexdsp srtp Secure RTP encryption (SDES) using libre SRTP-stack stdio Standard input/output UI driver stun Session Traversal Utilities for NAT (STUN) module swscale Video scaling using libswscale syslog Syslog module turn Obtaining Relay Addresses from STUN (TURN) module uuid UUID generator and loader v4l2 Video4Linux2 video source v4l2_codec Video4Linux2 video codec module (H264 hardware encoding) vidbridge Video bridge module vidinfo Video info overlay module vidloop Video-loop test module vp8 VP8 video codec vp9 VP9 video codec vumeter Display audio levels in console webrtc_aec Acoustic Echo Cancellation (AEC) using WebRTC SDK wincons Console input driver for Windows winwave Audio driver for Windows x11 X11 video output driver x11grab X11 grabber video source zrtp ZRTP media encryption module ``` ## IETF RFC/I-Ds: * RFC 2190 RTP Payload Format for H.263 Video Streams (Historic) * RFC 2250 RTP Payload Format for the mpa Speech and Audio Codec * RFC 2429 RTP Payload Format for 1998 ver of ITU-T Rec.

If your code is very large then please split it into smaller PRs. * The code must be tested on your platform. If the code involves SIP signaling or interop, it should also be tested against 3rd party SIP endpoints. * The code must compile with zero warnings * The code must pass "make ccheck" * Doxygen comments is nice to add, but it is not mandatory ## How to add new modules * https://github.com/baresip/baresip/wiki/How-to-add-new-modules baresip-1.0.0/docs/COPYING000066400000000000000000000030031372575704200151300ustar00rootroot00000000000000Copyright (c) 2010 - 2020, Alfred E.

Registration of MIME media type audio/MPA MIME media type name: audio MIME subtype name: MPA (MPEG audio) Required parameters: None Optional parameters: layer: which layer of MPEG audio encoding; permissible values are 1, 2, 3. samplerate: the rate at which audio is sampled. MPEG-1 audio supports sampling rates of 32, 44.1, and 48 kHz; MPEG-2 supports sampling rates of 16, 22.05 and 24 kHz. This parameter is separate from the RTP timestamp clock rate which is always 90000 Hz for MPA. mode: permissible values are "stereo", "joint_stereo", "single_channel", "dual_channel". The "channels" parameter does not apply to MPA. It is undefined to put a number of channels in the SDP rtpmap attribute for MPA. bitrate: the data rate for the audio bit stream. ptime: RECOMMENDED duration of each packet in milliseconds. maxptime: maximum duration of each packet in milliseconds. Parameters which are omitted are left to the encoder to choose based on the session bandwidth, configuration information, or other constraints. The selected layer as well as the sampling rate and mode are indicated in the payload so receivers can process the data without these parameters being specified externally. Encoding considerations: This type is only defined for transfer via RTP [RFC 3550]. Security considerations: See Section 5 of RFC 3555 Interoperability considerations: none Published specification: RFC 3551 Applications which use this media type: Audio and video streaming and conferencing tools. */ static bool mpa_mirror;
