WebM and Vorbis data seems out of date for Safari on iOS/iPadOS

Safari 14.1 (released October 20, 2020) added WebM and VP8/VP9/Vorbis support for macOS (data seems to be correct for this). However, it looks like iPadOS 15 and iOS 15 (released September 20, 2021) have also just gained support (link updated), although the iOS support is restricted to Vorbis audio only.

https://developer.apple.com/documentation/safari-release-notes/safari-15-beta-release-notes#Media doesn't appear to be working anymore, therefore first and last entry from the archive:

Tested using

• https://tests.caniuse.com/webm
• https://tests.caniuse.com/ogg-vorbis

and none of those media files worked for me, neither on iOS nor iPadOS 15 :/

Just tried again using the first iPadOS 16 public beta, same result as above: None of the files in the caniuse tests worked.

I'm afraid this issue can be closed, at least for the time being…

@Schweinepriester looks like it's being rolled out progressively: https://libreddit.kavin.rocks/r/apple/comments/hffam6/looks_like_apple_is_enabling_the_vp9_codec_for/

this issue was addressed by Safari 17.4 764442e ( #6997 (comment)).

There is a 17.4 regression though fixed in upcoming 17.5 affecting playback from audio blob (no matter if vorbis or opus codec in webm container): https://bugs.webkit.org/show_bug.cgi?id=245428 / WebKit/WebKit@a7b863a cc: @jensimmons
