Re-transcoding Videos

In this sample, you will learn how to retranscode multiple videos using the Dynamic Ingest API. To get access tokens and make the API calls, it uses a proxy built by Brightcove Learning services.

Overview

The Dynamic Ingest API call is exactly the same as it would be for ingesting new videos - the only difference is that you do not need to make a prior call to the CMS API to create the video object in the Video Cloud system and get an id for it, and the request body is slightly different. All videos will remain playable with existing renditions until retranscoding is complete.

Getting Credentials

To get a client_id and client_secret, you will need to go to the OAuth UI and register this app:

Managing API Authentication Credentials

These are the permissions you will need:

You can also get your credentials via CURL or Postman - see:

If you are getting credentials directly from the API, these are the permissions you need:

        [
          "video-cloud/video/all",
          "video-cloud/ingest-profiles/profile/read",
          "video-cloud/ingest-profiles/account/read",
          "video-cloud/upload-urls/read"
        ]

Proxy code

In order to build your own version the sample app on this page, you must create and host your own proxy. (The proxies used by Brightcove Learning Services only accept requests from Brightcove domains.) A sample proxy, very similar to the one we use, but without the checks that block requests from non-Brightcove domains, can be found in this GitHub repository. You will also find basic instructions for using it there, and a more elaborate guide to building apps around the proxy in Using the REST APIs.
