Bug#1062012: libwebkit2gtk-4.1-0: Video playback is buggy, particularly after seeking or resuming

[erusan]

Package: libwebkit2gtk-4.1-0
Version: 2.42.4-1
Severity: normal
X-Debbugs-Cc: erusan at gmail.com

Dear Maintainer,

Video playback is buggy on many (all?) sites, with regular YouTube and Odysee use confirming this issue.

Buggy behavior does not seem repeatable using the flatpak.

Loading a video on either site, then seeking around by holding arrow keys, clicking back and forth, pausing and then resuming, often yields frozen video, or video playing rapidly while audio continues at normal pace, or frozen video while audio plays, or spinner spinning forever with no resolution, or just plain frozen player.

Epiphany reports WebKitGTK 2.42.4 and GStreamer 1.22.8.

Again, this behavior does not seem to occur with the flatpak, but happens regularly (and has for I think a couple of years now) using the Debian repositories.
