这是一个由 声网Agora WebRTC团队提供的 WebRTC 镜像源，你可以使用此版本代替 Google 官方版本，此镜像保持与Chrome正式版同步，目前为M84。

如遇到问题，请在此地址发帖：https://rtcdeveloper.com/t/topic/14914

官方英文文档，请见：https://www.w3.org/TR/webrtc/

中文文档开源版本，请见：https://github.com/RTC-Developer/WebRTC-Documentation-in-Chinese

1. 环境配置

指定同步目录

export WORKSPACE=`pwd`

安装depot_tools

cd $WORKSPACE
rm -rf depot_tools && git clone https://webrtc.bj2.agoralab.co/webrtc-mirror/depot_tools.git
chmod +x $WORKSPACE/depot_tools/cipd
export PATH=$PATH:$WORKSPACE/depot_tools

同步WebRTC

mkdir -p $WORKSPACE/webrtc && cd $WORKSPACE/webrtc
vi .gclient
//添加以下内容
solutions = [
  { "name"        : "src",
    "url"         : "https://webrtc.bj2.agoralab.co/webrtc-mirror/src.git@65e8d9facab05de13634d777702b2c93288f8849",
    "deps_file"   : "DEPS",
    "managed"     : False,
    "safesync_url": "",
    "custom_deps": {
    },
  },
]
target_os = ["linux"]  /*根据需要Android, ios*/
//开始同步，时间较久
date; gclient sync; date
//出现提示是否使用谷歌的depot_tools，推荐“n”，或者等1分钟提示框超时。
//因为gclient sync获取源码之后，会向谷歌获取其它数据，如果因此报错，不想看到这个错误的话，可以设置代理之后再次sync
export http_proxy=x.x.x.x:port
export https_proxy=x.x.x.x:port
date; gclient sync; date

2. 编译

Linux

apt-get update
apt-get install -y g++
export PATH=$PATH:$WORKSPACE/depot_tools
cd $WORKSPACE/webrtc/src
./build/install-build-deps.sh
gn gen out/Release "--args=is_debug=false"
ninja -C out/Release

Android

# 安装依赖
apt-get install -y software-properties-common
add-apt-repository -y ppa:openjdk-r/ppa
./build/install-build-deps-android.sh
# 添加安卓平台
cd $WORKSPACE/webrtc
#echo "target_os = [ 'android' ]" >>.gclient
# 同步
export PATH=$PATH:$WORKSPACE/depot_tools
cd $WORKSPACE/webrtc && gclient sync --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab
# 编译
cd $WORKSPACE/webrtc/src
gn gen android/Release "--args=is_debug=false target_os="android" target_cpu="arm64""
ninja -C android/Release

iOS/macOS

export PATH=$PATH:$WORKSPACE/depot_tools
export CDS_CLANG_BUCKET_OVERRIDE=https://chromiumsrc.gitlab.io/commondatastorage/chromium-browser-clang
git.sh
# 安装depot_tools
cd $WORKSPACE
rm -rf depot_tools && git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git depot_tools
cd $WORKSPACE/depot_tools && git checkout gitlab
chmod +x $WORKSPACE/depot_tools/cipd
cd $WORKSPACE
rm -rf $WORKSPACE/webrtc && mkdir $WORKSPACE/webrtc
cd $WORKSPACE/webrtc && 
gclient config --name src https://chromium.googlesource.com/external/webrtc.git@gitlab
cd $WORKSPACE/webrtc && 
gclient sync
 --patch-ref=https://chromium.googlesource.com/chromium/src/build.git@gitlab
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
cd $WORKSPACE/webrtc/src && 
gn gen out/Release "--args=is_debug=false"
cd $WORKSPACE/webrtc/src && 
ninja -C out/Release
