Reported 2023-09-18 00:30:42 PDT
Issue: On IOS 17, Video playback is broken on Safari when a video element is proxied by AudioContext.createMediaElementSource. When video.play() is triggered, the video element is stuck on the first frame, there aren't any errors reported from HTMLVideoElement. Video Playback is fine when Web Audio API is not used. Replication: https://codepen.io/Ethan-Chong-the-solid/pen/mdaBxxP, open the Codepen on an iPhone with IOS 17. Play the video, it will stuck on the first frame without progressing.

Thank you for the report. Could you please clarify whether this is a new problem in iOS 17, or if you haven't tested earlier versions?
