The Livepeer Studio Transcode API lets you transcode video files that are stored in S3-compatible storage (e.g. Storj, W3S, AWS S3). You specify an input location (bucket/path) and output locations for HLS and/or MP4; Livepeer transcodes and writes the results to your storage.
The Transcode API works with any S3-compatible provider. You need valid S3 credentials (access key, secret key, endpoint, bucket) for both the source and destination.

​
Prerequisites

  • A Livepeer Studio account and API key.
  • Video file already uploaded to your S3-compatible bucket (e.g. via Storj uplink, AWS CLI, or S3 SDK).
  • S3 credentials with read access to the source path and write access to the output path.

​
Basic flow

  1. Get S3 credentials for your provider (e.g. Storj S3 credentials).
  2. Call the Transcode API with:
    • input: type s3, endpoint, credentials, bucket, path to the source video.
    • storage: type s3, endpoint, credentials, bucket (and optional path prefix for outputs).
    • outputs: e.g. hls: { path: "/output/hls" }, mp4: { path: "/output/mp4" }.
  3. Poll the returned task or listen for webhooks until the job completes. Output files appear in your bucket at the given paths.
For exact request shape and response, see the Transcode API reference. Code examples for Node.js and other languages are available in the Livepeer Studio docs.
