Description chris 2020-07-08 14:57:05 PDT
Fragmented MP4 (fMP4) media segments encrypted with whole-file AES-128 encryption do not play on Safari 13.1 (and iOS 13.5.1). Appears to be a regression as this worked as of June 3rd.

The referenced forum thread contains an example playlist demonstrating the issue.

This should be fixed in iOS 13.6 beta 2

Excellent, thanks -- any estimate on MacOS Safari?
