Hi ! I have continuous problem with Leap 42.3 / Firefox 58 can't play some youtube videos - "Your browser does not currently recognize any of the video formats available". Some effect with both SUSE builds and bins from Mozilla site. This tool https://www.youtube.com/html5 Detects H264 as unsupported format. Googling lead to this link https://support.mozilla.org/en-US/questions/1146825 which suggested this solution. https://forums.gentoo.org/viewtopic-p-7991240.html?sid=38ed7080bf31ac8987958... However, I don't have any third-party packages which install its own copy of libavcodec.so.57 rpm -qf /usr/lib64/libavcodec.so.57 libavcodec57-3.4.2-10.1.x86_64 (from openSUSE:Leap:42.3:Update) Anyone have any idea how to solve this problem? Thanks in advance. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
