【网络通信 -- WebRTC】项目实战记录 -- mediasoup android 适配 webrtc m94

【1】下载并配置 depot_tools

下载 depot_tools
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git

编辑 ~/.bashrc 将 depot_tools 添加到路径中
vim ~/.bashrc
export PATH=$PATH:/(path to depot_tools)/depot_tools
source ~/.bashrc

检查 depot_tools 是否安装配置成功
which gn
which gclient

【2】获取 WebRTC 源码

获取 Android WebRTC 代码
fetch --nohooks webrtc_android

若其中发生中断则执行如下命令继续
gclient sync

切换到 m94 分支并同步
cd src
git checkout -b m94 branch-heads/4606
cd ..
gclient sync --nohooks
gclient runhooks

下载安装相关依赖
cd src
./build/install-build-deps.sh
./build/install-build-deps-android.sh

【3】编译 WebRTC

编译 AAR

编译 libwebrtc.a 和 libwebrtc.jar
默认不会编译 webrtc 模块，在 /tools_webrtc/android/build_aar.py 文件中加入 ':webrtc'，如下

TARGETS = [
    ':webrtc',
    'sdk/android:libwebrtc',
    'sdk/android:libjingle_peerconnection_so',
]
--------------------------------------------------

开启 h264
修改 tools_webrtc/libs/generate_licenses.py 如下，添加 LICENSE

'g722': ['modules/third_party/g722/LICENSE'],
'fft4g': ['common_audio/third_party/fft4g/LICENSE'],
'spl_sqrt_floor': ['common_audio/third_party/spl_sqrt_floor/LICENSE'],
+    'openh264':['third_party/openh264/src/LICENSE'],
+    'ffmpeg':['third_party/ffmpeg/LICENSE.md'],
# TODO(bugs.webrtc.org/1110): Remove this hack. This is not a lib.
--------------------------------------------------

执行编译命令
./tools_webrtc/android/build_aar.py --extra-gn-args 'is_debug=false is_component_build=false is_clang=true rtc_include_tests=false rtc_use_h264=true rtc_enable_protobuf=false use_rtti=true use_custom_libcxx=false' --build-dir ./out/release-build/m94/
--------------------------------------------------

编译结果输出路径
out/release-build/m94/armeabi-v7a/obj/libwebrtc.a
out/release-build/m94/armeabi-v7a/lib.java/sdk/android/libwebrtc.jar

【4】保存 Webrtc Android 相关头文件与库

【5】适配 MediaSoup Android Client Lib

下载 mediasoup-client-android
git clone https://github.com/haiyangwu/mediasoup-client-android.git
将编译好的 webrtc m94 android 库的头文件与库文件拷贝到项目对应的 deps/webrtc 目录下

下载 mediasoup-demo-android
git clone https://github.com/haiyangwu/mediasoup-demo-android.git
settings.gradle 中配置 mediasoup-client-android 项目路径
build.gradle(:app) 中引用 mediasoup-client-android
即可编译 mediaoup-android APK
