http://bugzilla.opensuse.org/show_bug.cgi?id=1199210 Bug ID: 1199210 Summary: Firefox 99 no longer plays video content due to Tumbleweed FFMPEG / openh264 incompatibility Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Tumbleweed Status: NEW Severity: Normal Priority: P5 - None Component: Firefox Assignee: factory-mozilla@lists.opensuse.org Reporter: jphands@gmail.com QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- About 21 days ago, I reported a bug ( https://bugzilla.mozilla.org/show_bug.cgi?id=1764436 ) to the FireFox team, after a Tumbleweed update caused FireFox to stop playing some video content. Other browsers like Brave or Opera worked just fine, leading me to suspect Firefox. I worked with the FF team to run various tests and their eventual resolution is "wontfix" because the problem actually seems to be some packaging issue with FFMPEG and OPeH264...perhaps a version mismatch. One of the FF developers said "To fix the problem, you need to install the exact same version of https://software.opensuse.org/package/libopenh264-6 that was used to build OpenSuse's ffmpeg-5." The mozilla bug link above gives the full story. I have been unable to get Firefox to play video content, no matter what combination of FFMPEG and Openh264 I've tried, but this area isn't my strength. The FF people recommended that I open a bug with Tumbleweed, and perhaps together, the bug can be resolved. I'm available for any testing or experiments...just let me know. ==========================MACHINE INFO========================================== Operating System: openSUSE Tumbleweed 20220503 KDE Plasma Version: 5.24.4 KDE Frameworks Version: 5.93.0 Qt Version: 5.15.2 Kernel Version: 5.17.4-1-default (64-bit) Graphics Platform: X11 Processors: 24 � AMD Ryzen 9 3900X 12-Core Processor Memory: 47.0 GiB of RAM Graphics Processor: AMD DIMGREY_CAVEFISH -- You are receiving this mail because: You are the assignee for the bug.
