I expect gstreamer 1.28.0 to be released next week. It looks like https://github.com/WebKit/WebKit/pull/53872 needs to be fixed.

I'll just remove it for now, since we can check for 1.27.90 now that it is out. 2174720 5 philn 2026-01-24 02:12:39 -0800 Pull request: https://github.com/WebKit/WebKit/pull/57171 2174775 6 jbicha 2026-01-24 13:06:52 -0800 I confirm that pull request fixes my issue. 2174865 7 ews-feeder 2026-01-25 00:55:32 -0800 Committed 306164@main (6ab4390e676d): <https://commits.webkit.org/306164@main> Reviewed commits have been landed.
