git clone --recursive https://github.com/awslabs/amazon-kinesis-video-streams-producer-sdk-cpp.git우선 git clone을 통해 git 파일을 받아준다.
git을 받으면 이러한 폴더가 생성된것을 볼 수 있다.
sudo mkdir -p amazon-kinesis-video-streams-producer-sdk-cpp/build
cd amazon-kinesis-video-streams-producer-sdk-cpp/build이전으로 돌아와
해당 명령어를 통해서 build 폴더를 만들고 build 위치로 이동하면 된다.
해당 위치에서
cmake ..해당 명령어를 실행해주면 된다.
성공적으로 설치가 된다. 그뒤에는 라이브러리를 설치해주면 된다. 필요 라이브러리는 다음과 같다.
sudo apt-get install libssl-dev libcurl4-openssl-dev liblog4cplus-dev libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev gstreamer1.0-plugins-base-apps gstreamer1.0-plugins-bad gstreamer1.0-plugins-good gstreamer1.0-plugins-ugly gstreamer1.0-tools라이브러리를 설치가 완료 되었다면
상위 폴더로 올라와서
위와 같이 make 커맨드를 이용해주면 기본적으로 필요한 예제 코드나 빌드 파일들을 설치하게 된다.
예제 실행하기에 앞서서 환경 변수를 설정해준다. 설정하지 않으면 오류가 발생한다.

빌드가 실패했거나 GST_PLUGIN_PATH제대로 설정되지 않은 경우 다음 과 같은 출력이 표시된다.
No such element or plugin 'kvssink'성공적으로 완료가 되었다면
기본적으로 명령어로 실행이 가능하다. aws에서 비디오 스트리밍을 설정을 해두었다면
gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert ! video/x-raw,format=I420,width=640,height=480 ! omxh264enc control-rate=2 target-bitrate=512000 periodicity-idr=45 inline-header=FALSE ! h264parse ! video/x-h264,stream-format=avc,alignment=au,profile=baseline ! kvssink stream-name="스트림 이름" access-key="액세스키" secret-key="시크릿키" aws-region="설정된 지역"
이렇게 명령어를 입력하게 되면
위와 같이 실행 정보가 나오는 화면으로 가득 차게 된다.
아마존 서비스에 들어가게 되면 스트림이 생성되는것을 볼수 있다. 이를 통해서 명령어를 통해서 스트림 내용을 생성하는 것도 가능하다라는 것을 알 수 있다.
이렇게 재생되는 화면이 보인다면 정상적으로 된것이다.
스트림을 웹상에서 볼 수도 있는데 아래 사이트로 들어가서 필요한 부분에만 값을 넣어주면 확인할 수 있다.

하지만 Kinesis video streams 특성상 지연시간 3초에서 5초간이 있어 다른 스트리밍 방법도 찾아봐야 할 거 같다.
