@[email protected] they all use MediaSource API. the issue is: - on ios its not supported. so you'll either have to use ManagedMediaSource (non-standard safari-specific api only available on ios 17+) or use hls (natively supported by safari) - it supports a very limited number of codecs and encodings. and i have no control over this, except the ability to re-encode stuff browser-side - i wasn't really able to get it to work with my mp4 chunks
