This section explains how to build the project using CentOS 64 but could be easily adapted for any Linux, Windows or OS X.
sudo yum update
sudo yum install make libtool autoconf subversion git wget libogg-devel gcc gcc-c++ pkgconfig nasm
The first step is to checkout Doubango 2.0 source code:
git clone https://github.com/DoubangoTelecom/doubango.git
libsrtp is optional.
git clone https://github.com/cisco/libsrtp/
cd libsrtp
git checkout v1.5.0
CFLAGS="-fPIC" ./configure --enable-pic && make && make install
OpenSSL is required if you want to use the RTCWeb Breaker module or Secure WebSocket transport (WSS). OpenSSL version 1.0.1 is required if you want support for DTLS-SRTP.
This section is only required if you don’t have OpenSSL installed on your system or using version prior to 1.0.1 and want to enable DTLS-SRTP.
A quick way to have OpenSSL may be installing openssl-devel package but this version will most likely be outdated (prior to 1.0.1). Anyway, you can check the version like this:
openssl version
To build OpenSSL:
wget http://www.openssl.org/source/openssl-1.0.1c.tar.gz
tar -xvzf openssl-1.0.1c.tar.gz
cd openssl-1.0.1c
./config shared --prefix=/usr/local --openssldir=/usr/local/openssl && make && make install
libspeex (audio codec) an libspeexdsp (audio processing and jitter buffer) are optional. It’s highly recommended to enable libspeexdsp.
You can install the devel packages:
sudo yum install speex-devel
Or build the source by yourself:
wget http://downloads.xiph.org/releases/speex/speex-1.2beta3.tar.gz
tar -xvzf speex-1.2beta3.tar.gz
cd speex-1.2beta3
./configure --disable-oggtest --without-libogg && make && make install
YASM is only required if you want to enable VPX (VP8 video codec) or x264 (H.264 codec).
wget http://www.tortall.net/projects/yasm/releases/yasm-1.2.0.tar.gz
tar -xvzf yasm-1.2.0.tar.gz
cd yasm-1.2.0
./configure && make && make install
Date: December 1, 2012
libvpx adds support for VP8 and is optional but highly recommended if you want support for video when using Google Chrome or Mozilla Firefox.
You can install the devel packages:
sudo yum install libvpx-devel
Or build the source by yourself:
git clone http://git.chromium.org/webm/libvpx.git
cd libvpx
./configure --enable-realtime-only --enable-error-concealment --disable-examples --enable-vp8 --enable-pic --enable-shared --as=yasm
make && make install
libyuv is optional. Adds support for video scaling and chroma conversion.
mkdir libyuv && cd libyuv
svn co http://src.chromium.org/svn/trunk/tools/depot_tools .
./gclient config http://libyuv.googlecode.com/svn/trunk
./gclient sync && cd trunk
make -j6 V=1 -r libyuv BUILDTYPE=Release
#cp out/Release/obj.target/libyuv.a /usr/local/lib
#mkdir /usr/local/include/libyuv && cp -r include/* /usr/local/include/libyuv
libopus is optional but highly recommended as it’s an MTI codec for WebRTC. Adds support for Opus audio codec.
wget http://downloads.xiph.org/releases/opus/opus-1.0.2.tar.gz
tar -xvzf opus-1.0.2.tar.gz
cd opus-1.0.2
./configure --with-pic --enable-float-approx && make && make install
opencore-amr is optional. Adds support for AMR audio codec.
git clone git://opencore-amr.git.sourceforge.net/gitroot/opencore-amr/opencore-amr
cd opencore-amr && autoreconf --install && ./configure && make && make install
libgsm is optional. Adds support for GSM audio codec.
You can install the devel packages (recommended):
sudo yum install gsm-devel
Or build the source by yourself:
wget http://www.quut.com/gsm/gsm-1.0.13.tar.gz
tar -xvzf gsm-1.0.13.tar.gz
cd gsm-1.0-pl13 && make && make install
#cp -rf ./inc/* /usr/local/include
#cp -rf ./lib/* /usr/local/lib
G729 is optional. Adds support for G.729 audio codec.
svn co http://g729.googlecode.com/svn/trunk/ g729b
cd g729b
./autogen.sh && ./configure --enable-static --disable-shared && make && make install
iLBC is optional. Adds support for iLBC audio codec.
svn co http://doubango.googlecode.com/svn/branches/2.0/doubango/thirdparties/scripts/ilbc
cd ilbc
wget http://www.ietf.org/rfc/rfc3951.txt
awk -f extract.awk rfc3951.txt
./autogen.sh && ./configure
make && make install
Date: December 2, 2012
x264 is optional and adds support for H.264 video codec (requires FFmpeg).
wget ftp://ftp.videolan.org/pub/x264/snapshots/last_x264.tar.bz2
tar -xvjf last_x264.tar.bz2
# the output directory may be difference depending on the version and date
cd x264-snapshot-20121201-2245
./configure --enable-shared --enable-pic && make && make install
Date: December 2, 2012
FFmpeg is optional and adds support for H.263, H.264 (requires x264) and MP4V-ES video codecs.
git clone git://source.ffmpeg.org/ffmpeg.git ffmpeg
cd ffmpeg
# grap a release branch
