Get pre-signed URL

Use this API to generate a short-lived pre-signed URL for a recording asset.

By default, the generated URL has an expiry of 3 days for AWS S3 and GCS buckets and 9 hours for Alibaba OSS storage. You can pass a ?presign_duration=number query param to control the validity of the URL.

curl --location --request GET '<asset_id>/presigned-url' \ --header 'Authorization: Bearer <management_token>'
Status: 200 OK
{ "id": "<asset-id>", "path": "<path-of-asset>", "url": "<presigned-url>", "expiry": 3600 // in seconds }

Note on url in the API response

In the case of room-vod asset type, the url can contain 3 things depending on the configured storage and VOD upload format. It will contain:

  • Pre-signed URL to let you download the zipped VOD file if the VOD upload format is 'zipped', irrespective of the configured storage.
  • CDN URL which can be put in any HLS compatible player to play the VOD file if the configured storage is 100ms' and the VOD upload format in 'Unzipped'.
  • Pre-signed URL to the M3U8 file which is not playable if the configured recording storage is the user's cloud bucket and the VOD upload format is 'Unzipped'.
