http://bugzilla.opensuse.org/show_bug.cgi?id=1140434 Bug ID: 1140434 Summary: Reduced video quality in vlc/kaffeine since 5.1.10 Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: x86-64 OS: openSUSE Factory Status: NEW Severity: Normal Priority: P5 - None Component: KDE Applications Assignee: opensuse-kde-bugs@opensuse.org Reporter: Michael.Zapf@mizapf.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- After the upgrade to 5.1.10, the video quality in VLC and kaffeine (using the vlclib) has significantly degraded. It seems as if the vertical resolution has been reduced to 50%, then stretched to fill the frame. vlc was not updated (3.0.7.1 "Vetinari"), so I suspect that the different behavior comes from the kernel update. Here are links that show screenshots I created on the openSUSE KDE Plasma desktop. In both cases, the same program was being shown; I reverted to the previous kernel in the meantime using "start with read-only snapshot". Have a closer look at the TV station logo in the upper left corner to spot the difference most easily. With kernel 5.1.7: http://www.mizapf.eu/files/vlc_5.1.7.png With kernel 5.1.10: http://www.mizapf.eu/files/vlc_5.1.10.png Here is one final screenshot that shows another point of different behavior. When vlc is started, the video output is only half-height for about 1 second or slightly less. Then, the video is stretched to the window height. I created this snapshot by launching VLC and then quickly creating a screenshot. http://www.mizapf.eu/files/vlc_5.1.10_sec1.png I just updated to the newest release 5.1.15, but the reduced quality is still there. -- You are receiving this mail because: You are on the CC list for the bug.
