Specify Closed Captions for HLS delivery

After you set up the set-akamai-hls-revision query string, you can enable Closed Captions for your HLS output using the set-cc-attribute query string on per-stream basis. Closed Captions are usually embedded into your video asset.

For details on the supported Closed Captions, refer to Use Closed Captioning.

The following examples show you how to use the set-akamai-hls-revision query string.
