이 페이지에서는 Live Stream API의 개요를 제공합니다. Live Stream API는 여러 기기 플랫폼용으로 메자닌 실시간 신호를 HTTP 동적 적응형 스트리밍(DASH/MPEG-DASH), HTTP 실시간 스트리밍(HLS)을 비롯한 소비자 직접 스트리밍 형식으로 트랜스코딩합니다.
먼저 입력 엔드포인트를 만든 후 실시간 SRT 또는 RTMP 입력 신호를 HLS 또는 DASH 출력 스트림으로 트랜스코딩하는 채널 리소스를 만듭니다.
Live Stream API로 생성된 출력 스트림은 Cloud Storage 버킷에 저장됩니다. 그런 다음 Cloud Storage 버킷을 Media CDN의 백엔드로 구성할 수 있습니다.

The Live Stream API\ntranscodes mezzanine live signals into direct-to-consumer streaming formats,\nincluding Dynamic Adaptive Streaming over HTTP (DASH/MPEG-DASH), and HTTP Live\nStreaming (HLS), for multiple device platforms.\n\nYou first create an input endpoint, then create a channel resource that\ntranscodes the live SRT or RTMP input signal into an HLS or DASH output stream.\nOutput streams created by the Live Stream API are saved to Cloud Storage\nbuckets. You can then configure a Cloud Storage bucket as a backend for\nMedia CDN.\n\nFeatures\n--------\n\nThe Live Stream API includes support for the following features:\n\n- Automatic infrastructure provisioning\n\n- Integration with Cloud Storage, Cloud Audit Logs, and Google Cloud\n infrastructure\n\n- Configuration of a backup input stream for redundancy\n\n- Live to video on demand (VOD)\n\n- Content encryption\n\n- Slates (image and video)\n\n### Supported inputs and outputs\n\nThe following tables show the supported input and output formats for the\nLive Stream API.\n\nSee the\n[supported configurations for content encryption](/livestream/docs/how-to/encrypt-content#supported-configurations).\n\nAccess control\n--------------\n\nThe Live Stream API access control model is based on\n[Identity and Access Management (IAM)](/iam/docs). IAM's fine-grained\npermissions give you control over what can be done with media data, and by whom.\n\nConcepts and terminology\n------------------------\n\nThis section provides a glossary of useful terms for working with the\nLive Stream API.\n\n### Channels\n\nA channel is a resource that ingests the input stream through an input endpoint,\ntranscodes the input stream into multiple renditions, and publishes output live\nstreams in certain formats in the specified location. You can include a primary\nand backup input stream in the same channel.\n\n### Channel events\n\nA channel event is a sub-resource of a channel that executes operations on a\nchannel resource without needing to stop the channel. The following channel\nevents are supported:\n\n- Create ad break markers\n- Mute/unmute the live stream\n- Insert a slate into the live stream\n- Return to program (live stream)\n- Switch the channel input\n\n### Encoder\n\nAn encoder is a program used to send input streams, such as `ffmpeg`.\n\n### Input endpoints\n\nAn input endpoint is an endpoint to which your encoder sends your input stream.\nYou can use the input endpoint to specify configurations for your stream, such\nas input resolution, input type, and video cropping.\n\nAn input endpoint consists of either an RTMP or SRT URI that looks like the\nfollowing: \n\n```\nrtmp://192.0.2.1/live/STREAM_ID\n``` \n\n```\nsrt://192.0.2.1:4201?streamid=STREAM_ID\n```\n\nwhere \u003cvar translate=\"no\"\u003e\u003ccode translate=\"no\" dir=\"ltr\"\u003eSTREAM_ID\u003c/code\u003e\u003c/var\u003e is a string such as\n`b8ebdd94-c8d9-4d88-a16e-b963c43a953b`."]]
