EC2安装WebRTC sdk-c环境、构建、编译

1、登录新的ec2实例，证书可以跟之前的实例用一个：

ssh -v -i ~/Documents/cert/qa.pem [e-mail]

2、按照sdk-c demo中readme的描述开始安装环境：

https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c

2-1、 安装git：

sudo dnf install git -y
git --version

2-2、clone sdk-c项目：

git clone https://github.com/awslabs/amazon-kinesis-video-streams-webrtc-sdk-c.git --single-branch -b main kvs-webrtc-sdk

2-3、下载并安装 OpenSSL 1.1.1t版本（这里说明一下，通过构建sdk-c项目时自动下载OpenSSL我这边每次都timeout；包管理器dnf 默认只安装 仓库中当前可用的版本，不支持直接通过 dnf install openssl-devel-1.1.1t 来安装旧版本）：

# 安装依赖
sudo dnf groupinstall "Development Tools" -y
sudo dnf install perl-core zlib-devel -y# 下载源码（1.1.1t）
wget https://www.openssl.org/source/openssl-1.1.1t.tar.gz
tar -xf openssl-1.1.1t.tar.gz
cd openssl-1.1.1t# 指定安装路径（例如 /usr/local/openssl-1.1.1t）
./config --prefix=/usr/local/openssl-1.1.1t --openssldir=/usr/local/openssl-1.1.1t
make -j$(nproc)
sudo make install

2-4、OpenSSL 1.1.1t设置环境变量：

Amazon Linux 的默认 shell 启动文件是 ~/.bash_profile，

nano ~/.bash_profile

# >>> OpenSSL 1.1.1t config >>>
export PATH=/usr/local/openssl-1.1.1t/bin:$PATH
export LD_LIBRARY_PATH=/usr/local/openssl-1.1.1t/lib:$LD_LIBRARY_PATH
export PKG_CONFIG_PATH=/usr/local/openssl-1.1.1t/lib/pkgconfig
# <<< OpenSSL 1.1.1t config <<<

保存并退出编辑器，Ctrl + X -> Y -> 回车，

让改动立即生效：

source ~/.bash_profile

验证是否生效：

[ec2-user@ip-xx-10-0-xxx ~]$ openssl version
OpenSSL 1.1.1t  7 Feb 2023

2-5、修改CMakeList.txt

cd kvs-webrtc-sdk/
nano CMakeList.txt

Ctrl+w，搜索关键词：build_dependency，将：

    build_dependency(openssl ${BUILD_ARGS})set(OPENSSL_ROOT_DIR ${OPEN_SRC_INSTALL_PREFIX})

修改为：

    # build_dependency(openssl ${BUILD_ARGS})set(OPENSSL_ROOT_DIR "/usr/local/openssl-1.1.1t")

保存退出。

2-6、安装基础依赖：

sudo dnf install -y cmake m4 pkgconf-pkg-config openssl-devel libcurl-devel

2-7、安装 GStreamer 及其相关开发包：

sudo dnf install -y \gstreamer1-devel \gstreamer1-plugins-base-devel \gstreamer1-plugins-bad-free-devel

这块儿要说一下，gstreamer1有的插件在Amazon Linux 2023 的默认仓库中可能没有提供，或者它们已经被拆分、重命名或移除。所以在安装过程中会报错，例如：

Error: Unable to find a match: gstreamer1-plugins-good-devel gstreamer1-libav-devel

所以先search一下，看支持哪些插件：

[ec2-user@ip-xx-10-0-xxx ~]$ dnf search gstreamer1 | grep devel
Last metadata expiration check: 1:56:26 ago on Mon Jun  9 09:41:13 2025.
gstreamer1-devel.x86_64 : Libraries/include files for GStreamer streaming media framework
gstreamer1-plugins-bad-free-devel.x86_64 : Development files for the GStreamer media framework "bad" plug-ins
gstreamer1-plugins-base-devel.x86_64 : GStreamer Base Plugins Development files

确认一下gstreamer版本：

[ec2-user@ip-10-10-0-103 ~]$ pkg-config --modversion gstreamer-1.0
1.24.10

3、构建

3-1、先创建build目录：

mkdir -p kvs-webrtc-sdk/build
cd kvs-webrtc-sdk/build/

3-2、构建：

cmake .. \-DBUILD_OPENSSL=OFF \-DOPENSSL_ROOT_DIR=/usr/local/openssl-1.1.1t \-DOPENSSL_INCLUDE_DIR=/usr/local/openssl-1.1.1t/include \-DOPENSSL_USE_STATIC_LIBS=FALSE \-DUSE_OPENSSL_SYSTEM=ON \-DUSE_OPENSSL_FROM_SOURCE=OFF

4、编译

make -j$(nproc)

[ec2-user@ip-xx-10-0-xxx build]$ make -j$(nproc)
