Bug ID: 416828
Summary: dolphin is removed when VDPAU is uninstalled
Product: dolphin
Version: 17.12.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: dolphin-bugs-n...@kde.org
Reporter: k...@bluewin.ch
CC: kfm-de...@kde.org
Target Milestone: ---
SUMMARY
Well, this may be not directly a bug. But when the VDPAU (video decoding
acceleration API) is uninstalled with "sudo apt-get remove mesa-vdpau-drivers
libvdpau1 vdpauinfo" also the dolphin file manager is removed from the system.
This is a somewhat strange behavior, - for a file manager.
STEPS TO REPRODUCE
1. Execute the command "sudo apt-get remove mesa-vdpau-drivers libvdpau1
vdpauinfo" in the terminal
OBSERVED RESULT
The dolphin file manager is removed along the VDPAU packages.
EXPECTED RESULT
When VDPAU is uninstalled, dolphin should not be removed. And if dolphin needs
any form of "video acceleration" (?), it should use the VA-API instead of
VDPAU.
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Kubuntu 18.04
(available in About System)
KDE Plasma Version: 5.12.9
KDE Frameworks Version: 5.44.0
Qt Version: 5.9.5
ADDITIONAL INFORMATION
The effective reason to remove VDPAU is because it is broken for some hardware.
As of January 2020 this is true for most newer Radeon (r600) MESA driver
releases. In most cases, with some rare exceptions, the VA-API is working
stable. So a switch to that video decoding acceleration API would be a good
workaround.
