WebRTC-Streamer交叉编译
flyfish 2023-08-28 2023-09-01 2023-09-22 新增 CentOS版本docker下运行 文章目录 WebRTC-Streamer交叉编译零、前言一、提前准备工作1 安装需要的工具2 可选的交叉编译工具3 默认执行python是python34 获取源码5 使用其他版本的方法 二、非交叉编译编译1 在 src目录执行 安装所需的依赖2 执行命令 三、 交叉编译1 独立使用的方法，无需提供给WebRTC-Streamer使用的方法2 提供给WebRTC-Streamer使用的方法 四、开始编译WebRTC-Streamer五、以下是不同版本的编译，可能出现的错误和解决方案问题1缺少rtmp问题 2 链接问题问题3 live555helper问题4 WebRTC和WebRTC-Streamer两者版本，其中之一过旧或者过新问题问题5 未安装工具的错误问题6 编译工具与代码版本问题问题7 使用clang或者gcc不同编译器编译的情况 零、前言WebRTC-Streamer源码 https://github.com/mpromonet/webrtc-streamer官网给的三步是 1安装 Chromium depot tools pushd .. git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git export PATH=$PATH:`realpath depot_tools` popd2 下载 WebRTC mkdir ../webrtc pushd ../webrtc fetch --no-history webrtc popd3 构建 WebRTC Streamer cmake . && make这里实践第三步首先要编译WebRTC，然后再编译WebRTC-Streamer webrtc编译 一、提前准备工作 1 安装需要的工具 sudo apt-get install build-essential pkg-config devhelp glade libglade2-dev sudo apt-get install libgtk-3-dev sudo apt install ninja-build sudo apt install git sudo apt install libcanberra-gtk-module sudo apt install cmake sudo apt install python3-pip pip3 install dataclasses 2 可选的交叉编译工具 https://mirrors.tuna.tsinghua.edu.cn/armbian-releases/_toolchain/ 3 默认执行python是python3 sudo rm /usr/bin/python sudo ln -s /usr/bin/python3 /usr/bin/python python --version 4 获取源码 git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git创建webrtc文件夹 终端命令进入webrtc文件夹后，执行命令 加载路径 export PATH=/path/to/depot_tools:$PATH替换成depot_tools所在路径，这里用的是 export PATH="$PATH:/home/a/source/depot_tools/" fetch --nohooks webrtc gclient sync 5 使用其他版本的方法切换到分支方法 查看有哪些版本 https://webrtc.github.io/webrtc-org/release-notes/
进入 webrtc/src目录，执行命令 git checkout -b m85 branch-heads/4183 gclient sync或者通过git branch -r 查看有哪些分支 二、非交叉编译编译可编译x86_64版本 1 在 src目录执行 安装所需的依赖 ./build/install-build-deps.sh这里实际用的是 ./build/install-build-deps.sh --no-chromeos-fonts #跳过字体的安装 2 执行命令 gn gen out/Default --args='is_debug=false' ninja -C out/Default 三、 交叉编译可编译arm32或者arm64版本 根据自己需要选择 1 独立使用的方法，无需提供给WebRTC-Streamer使用的方法如果是要交叉编译，需要执行 ./build/linux/sysroot_scripts/install-sysroot.py --arch=arm #32位 ./build/linux/sysroot_scripts/install-sysroot.py --arch=arm64 #64位普通的交叉编译 第一步 gn gen out/linux_arm --args='target_os="linux" target_cpu="arm" use_custom_libcxx=false' #32位 gn gen out/linux_arm64 --args='target_os="linux" target_cpu="arm64" use_custom_libcxx=false' #64位第二步 ninja -C out/linux_arm #32位 ninja -C out/linux_arm64 #64位 2 提供给WebRTC-Streamer使用的方法交叉编译命令 还可以是如下命令 假如是arm32下 第一步 gn gen out/Release --args=‘rtc_use_x11=false rtc_use_pipewire=false is_clang=true use_sysroot=false target_cpu=“arm” is_chrome_branded=true is_debug=false use_custom_libcxx=false rtc_include_tests=false rtc_enable_protobuf=false rtc_build_examples=false rtc_build_tools=false treat_warnings_as_errors=false rtc_enable_libevent=false rtc_build_libevent=false use_ozone=true rtc_build_json=true’ 第二步 ninja -C out/Release webrtc rtc_json jsoncpp builtin_video_decoder_factory builtin_video_encoder_factory peerconnection p2p_server_utils task_queue default_task_queue_factory 四、开始编译WebRTC-Streamer以arm32为例 cmake -DCMAKE_SYSTEM_PROCESSOR=armv7l -DCMAKE_SYSTEM_NAME=Linux -DCMAKE_C_COMPILER=/home/a/tool/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-gcc -DCMAKE_CXX_COMPILER=/home/a/tool/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin/arm-linux-gnueabihf-g++ -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY -DCMAKE_FIND_ROOT_PATH_MODE_PACKAGE=ONLY -DWEBRTCOZONE=Yes -DWEBRTCDESKTOPCAPTURE=OFF . 以上编译命令类似 set(CMAKE_SYSTEM_NAME Linux) set(CMAKE_SYSTEM_PROCESSOR arm) set(tools /home/a/tool/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/) set(CMAKE_C_COMPILER ${tools}/bin/arm-linux-gnueabihf-gcc) set(CMAKE_CXX_COMPILER ${tools}/bin/arm-linux-gnueabihf-g++) set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER) set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY) set(CMAKE_FIND_ROOT_PATH_MODE_PACKAGE ONLY)可选的 set(CMAKE_SYSROOT /home/devel/rasp-pi-rootfs) set(CMAKE_STAGING_PREFIX /home/devel/stage)如果不想写这么长的工具路径，可以如下操作 usr/local/下建立一个arm32文件夹，将工具拷贝进去 编辑~/.bashrc加上一句 export PATH=$PATH:/usr/local/arm32/gcc-arm-8.3-2019.03-x86_64-arm-linux-gnueabihf/bin 五、以下是不同版本的编译，可能出现的错误和解决方案 问题1缺少rtmp In file included from /home/a/source/webrtc-streamer/inc/CapturerFactory.h:34, from /home/a/source/webrtc-streamer/src/PeerConnectionManager.cpp:26: /home/a/source/webrtc-streamer/inc/rtmpvideosource.h:32:10: 致命错误： librtmp/rtmp.h：没有那个文件或目录 #include ^~~~~~~~~~~~~~~~ 编译中断。 CMakeFiles/webrt方式1： 下载 http://rtmpdump.mplayerhq.hu/download/ rtmpdump-2.3放置到 librtmp /home/a/source/webrtc-streamer/inc/librtmp然后再解决链接问题 arm-linux-gnueabihf/bin/ld: cannot find -lrtmp arm-linux-gnueabihf/bin/ld: cannot find -lz arm-linux-gnueabihf/bin/ld: cannot find -lgmp方式2 不使用rtmp 更改CMakeList.txt # rtmp ?

LLVM： clang / clang++（https://clang.llvm.org/） GNU： gcc / g++（ https://gcc.gnu.org/） 同样 的编译参数-std=c++17在默认的情况下，是用了不同的标准库 g++ with libstdc++ (by default) clang++ with libc++ (by default)在使用gcc编译的情况下，使用系统级别的函数时ibstdc++会调用glibc，Host上的gcc如果使用的glibc过高，到了Target就运行不起来 CentOS版本docker 运行 sudo yum install -y yum-utils sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo sudo yum install docker-ce docker-ce-cli containerd.io sudo systemctl start docker sudo docker run hello-world sudo docker run -p 8000:8000 -v $PWD/config.json:/app/config.json mpromonet/webrtc-streamer参考 https://webrtc.org.cn/mirror/ https://developer.mozilla.org/en-US/docs/Web/API/WebRTC_API |
