What's new in HLS
summary
Content Steering is now a speced flow (v1.2b1) using an EXT-X-Content-Steering tag that points to a steering server and a pathway ID; the steering manifest returns Version TTL Reload-URI and an ordered Pathway Priority list so clients can switch CDNs on the fly. Renditions gain a pathway parameter (redundant-stream style). Interstitials use EXT-X-DATERANGE with class com.apple.hls.Interstitial and attributes like X-ASSET-URI X-ASSET_LIST X-RESUME_OFFSET X-Playout-Limit and X-Snap. iOS/tvOS 15 ships support (betas require entitlements); HLS.js work is in progress.
