北向应用使用webrtc二进制文件

简介

北向应用集成webrtc的方法除了通过源码方式集成，也可以直接集成已交叉编译好的二进制文件。本文主要介绍如何将二进制文件集成到应用中。

注意：集成到北向应用的二进制文件必须是通过OpenHarmony的SDK交叉编译生成的，不能是通过rom方式编译生成的。

集成方法

交叉编译webrtc

交叉编译的方法可以参照文档webrtc_adapter_ohos.md

获取webrtc头文件

进入webrtc目录，执行下面shell脚本

#!/bin/bash

mkdir include

src=`find ./ -name "*.h*"`
for obj in $src
do
	echo "$src"
	cp --parents $obj ./include
done

include目录即是webrtc所需头文件

应用中调用webrtc

  1. 将webrtc生成的二进制文件拷贝到应用工程目录

    为了更好的管理应用集成的ohos_webrtc，在应用工程的cpp目录新建一个thirdparty目录，将生成的二进制文件以及头文件拷贝到该目录下，如下图所示,ohos_webrtc代表的是三方库名称，ohos_webrtc文件夹下包含了arm架构以后aarch64架构2种方式生成的二进制文件，每种架构目录下包含了该库的头文件(include)以及二进制文件(lib)：

  2. 配置相关参数

    配置相关参数只需要在cpp目录的CMakeLists.txt文件中添加

    set(CMAKE_CXX_STANDARD 17)
set(WEBRTC_PATH ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/ohos_webrtc/${OHOS_ARCH}/include)

  3. 配置对应链接

    配置链接只需要在cpp目录的CMakeLists.txt文件中添加对应target_link_libraries即可：

    • 配置静态库链接
    target_link_libraries(entry PUBLIC ${CMAKE_CURRENT_SOURCE_DIR}/thirdparty/ohos_webrtc/${OHOS_ARCH}/lib/libwebrtc.a)

  4. 配置头文件路径

    配置链接只需要在cpp目录的CMakeLists.txt文件中添加对应target_include_directories

    target_compile_definitions(entry PUBLIC -DWEBRTC_POSIX)
target_include_directories(entry PUBLIC ${WEBRTC_PATH})
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/abseil-cpp)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/boringssl)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/catapult)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/crc32c)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/dav1d)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/ffmpeg)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/fontconfig)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/fuzztest)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/google_benchmark)

target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/catapult)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/libc++)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/libc++abi)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/libevent)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/libjpeg_turbo)
target_include_directories(entry PUBLIC ${WEBRTC_PATH}/third_party/libpng)
