It is severe issue that affects wide range of IOS devices 1830101 8 youennf 2022-01-12 05:53:07 -0800 Just had a quick look, and the issue is probably related to fallback decoder being using VTB instead of Libvpx as it should. The temp workaround would be to not rely on kSVC downstream. 1830102 9 448938 youennf 2022-01-12 06:02:07 -0800 Created attachment 448938 Patch 1830185 10 ews-feeder 2022-01-12 09:58:37 -0800 Committed r287928 (245961@main): <https://commits.webkit.org/245961@main> All reviewed patches have been landed.
