What configuration are you using? What is the output of player.getNonDefaultConfiguration()?

{}

What did you do?

• Go to https://shaka-player-demo.appspot.com/demo/#audiolang=en-US;textlang=en-US;uilang=en-US;panel=CUSTOM%20CONTENT;build=uncompiled
• Use the above manifest URIs
• Find the video loading forever (no network calls seem to made to AMS)

What did you expect to happen?
The player should play the whole video

What actually happened?

Following the issue: 7483, the AMS manifests are working now on Windows & Edge browsers. However, we are still unable to play the videos on iOS & Mac Safari browsers.

There is no detailed error message getting logged from shaka on demo-app and we do not see any outgoing Fragment API requests to AMS.

Note that AMS manifest(s) works on Safari devices on dash.js - MSS but not on shaka player.

No
