Bug ID: 203465
Summary: [GStreamer] Crash playing reddit video
Product: WebKit
Version: WebKit Nightly Build
Hardware: PC
OS: Linux
Status: NEW
Severity: Normal
Priority: P2
Component: Media
Assignee: webkit-unassigned at lists.webkit.org
Reporter: mcatanzaro at gnome.org
Visit https://www.reddit.com/r/StLouis/comments/dmznic/alderwoman_tell_st_louisans_they_better_pay_in/ in Tech Preview (with 2.26.1) and play the video. It always crashes at 19s. Looks like something going wrong inside GstOpenh264Dec, but I'll leave it to multimedia folks to forward upstream if required....
