            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-null at kde.org
          Reporter: kle at bluewin.ch
                CC: kfm-devel at 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.
