MediaConvert KotlinSDK용 사용 예제
다음 코드 예제에서는 와 함께 for Kotlin을 AWS SDK 사용하여 작업을 수행하고 일반적인 시나리오를 구현하는 방법을 보여줍니다 MediaConvert.
작업은 대규모 프로그램에서 발췌한 코드이며 컨텍스트에 맞춰 실행해야 합니다. 작업은 개별 서비스 함수를 직접적으로 호출하는 방법을 보여주며 관련 시나리오의 컨텍스트에 맞는 작업을 볼 수 있습니다.
각 예제에는 컨텍스트에서 코드를 설정하고 실행하는 방법에 대한 지침을 찾을 수 있는 전체 소스 코드에 대한 링크가 포함되어 있습니다.
