Bug ID: 524240
Summary: H.264 Video stored in MKV no longer playable after
update
Classification: Applications
Product: Haruna
Version First 1.8.1
Reported In:
Platform: CachyOS
OS: Linux
Status: REPORTED
Severity: critical
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
DESCRIPTION
After updating to the newest version of Haruna, it fails to open and play H.264
MKV files. I am not sure if the issue is limited to just that codec and
container. Double-clicking a file in Dolphin opens a blank Haruna window. Then
trying to open the file from Haruna makes the message stating that the video
track is missing appear. Opening Haruna via terminal yields the following:
unknown() : The graphics api must be set to opengl or mpv won't be able to
render the video.
QQuickWindow::setGraphicsApi(QSGRendererInterface::OpenGL)
The call to the function must happen before constructing the first QQuickWindow
in the application.
WARNING: radv is not a conformant Vulkan implementation, testing use only.
STEPS TO REPRODUCE
1. Open an H.264 MKV file
OBSERVED RESULT
Video track not found when opening via Haruna. Video does not load at all when
opening via Dolphin.
EXPECTED RESULT
Video plays.
