클립은 Brightcove Social및 기타 도구에서 생성한 다른 비디오의 세그먼트로 만든 비디오입니다. 클립이 Brightcove Social을 통해 공유하기 위해 생성 된 경우 해당 변환을 제거하여 관리되는 저장소를 줄이고 /하거나 비디오 워크 플로에 표시되지 않도록 비활성화 할 수 있습니다.
클립 찾기
계정에서 클립을 찾는CMS API데 도움이 되는 특수 검색어가 있습니다.
q=%2Bis_clip:true- 클립만 반환합니다.q=%2Dis_clip:true-비 클립 만 반환q=%2Bis_clip:false-비 클립 만 반환 (이전 항목과 기능적으로 동일)q=%2Bclip_source_video_id: video_id-지정된 비디오에서 생성 된 클립을 반환합니다.

자산 제거
클립을 소셜 미디어 사이트에 공유하는 것 이외의 다른 목적으로 사용하지 않으려면 클립에서 자산을 제거하여 관리 스토리지를 줄일 수 있습니다. 스토리지 측면에서 렌 디션이 가장 큰 차이를 만들지 만 원하는 경우 포스터와 썸네일도 제거 할 수 있습니다 (일반 용도의 비디오가 아닌 Studio의 클립을 식별하는데도 도움이 됨).
자산을 제거하려면 CMS API의 자산 엔드포인트를 사용합니다 . 논리는 간단합니다. 먼저 자산을 가져 와서 Video Cloud 시스템에서 ID를 검색 한 다음 삭제합니다.
일반적으로 삭제할 포스터와 썸네일은 하나만 있지만 일반적으로 여러 렌 디션이 있으므로 프로그래밍 방식으로이 작업을 수행하려면 GET 렌 디션 요청에 의해 반환 된 객체 배열을 반복하고 삭제해야합니다. 하나씩 변환합니다. 다음은 자산 제거 작업을 수행하기위한 관련 API 엔드 포인트와 일부 샘플 코드 (JavaScript + API 요청을 만들기 위해 PHP로 작성된 프록시)입니다.
자산 끝점
자산을 제거하는 데 필요한 관련 자산 엔드 포인트는 다음과 같습니다. 이러한 모든 엔드 포인트의 기본 URL은 다음과 같습니다.
https://cms.api.brightcove.com/v1/accounts
렌디션
GET 변환
/account_id/videos/video_id/assets/renditions
변환 삭제
/account_id/videos/video_id/assets/renditions/rendition_id
포스터

/account_id/videos/video_id/assets/poster
포스터 삭제
/account_id/videos/video_id/assets/poster/poster_id
썸네일
GET 썸네일
/account_id/videos/video_id/assets/thumbnail
미리보기 이미지 삭제
/account_id/videos/video_id/assets/thumbnail/thumbnail_id
샘플 앱
다음은 계정의 모든 클립을 찾은 다음 모든 변환과 각 클립의 포스터 및 썸네일을 제거하는 앱의 샘플 코드입니다.
