Survive CDN failures with Redundant Streams

The text discusses the challenges of maintaining consistent video streaming quality due to potential internet-wide service outages. It explains how Mux Video, a platform that already uses multiple CDNs for content delivery, is working on improving its resilience to such issues by implementing mid-stream CDN switching. This involves using HLS Redundant Streams, which allows the player to treat multiple HLS renditions with identical characteristics as redundant sets for failover purposes. The text also provides a compatibility grid of popular video players and instructions on how to enable redundant streams in Mux Video.
