Hi Dustin,

The Service Worker approach is definitely working for us in production on iOS 15 and iPad OS 15. It's the only way we've found to avoid the massive delay (10s or more) in playback starting (accompanied by very high CPU and memory usage).

Is your non-worker Blob solution not suffering those effects? We're using it for more "normal" resolution files - 10MBish, 720p or so - direct blob or data uri approaches were fine in iOS 14 but unusable in iOS 15, the Service Worker approach did get those videos to work OK for us. I imagine there's still some extra overhead from having JS involved in the network request path though.
