Example/Usage

const api = videoIndexer({
  accountId: 'the-account-id',
  location: 'the-location',
  subscriptionKey: 'the-subscription-key',
})

// to get the cached token
const accessToken = await api.getToken()

// to index a video
const videoURL = 'https://url-to-a-downloadable-cloud-resource'
const uuid = 'id-recognising-the-video-on-your-platform'

await api.indexVideo(videoURL, {
  name: 'Into the Spiderverse',

})

API

getToken(forceFetch?)

Returns a promise to a cached access token. This functions ensures you don't always have to poll the access token

it's fetched once and cached using simple cache for t < 60sec before it's refreshed.
token is always valid within a 1hr expiry period.

forceFetch Type: undefined|boolean

Set to true to fetch a new token

indexVideo(videoURL, options)

Used to ingest a video to be analyzed.

videoURL Type: string

Video file url to analyze. The URL must point to a media file (HTML pages are not supported). Please read more here. Be aware of cases where the video file is protected by an access token and note that those must be encoded properly. See this Stack Overflow question
