Bug ID: 492696
Summary: Screen Grab results in an error message due to missing
x11grab capability of ffmpeg
Classification: Applications
Product: kdenlive
Version: 24.08.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: User Interface
Assignee: j...@kdenlive.org
Reporter: bern...@yahoo.com
Target Milestone: ---
SUMMARY
It is impossible to do a screen recording or screen grab from within Kdenlive
due to ffmpeg not having the --enable-x11grab parameter.
According to an internet search, --enable-x11grab has been deprecated in favor
of --enable-libxcb.
STEPS TO REPRODUCE
1. Perform a Screen Grab
OBSERVED RESULT
Error message:

SOFTWARE/OS VERSIONS
Linux: Pop!_OS 22.04
KDE Frameworks Version: 6.5
Qt Version: 6.7.2
ADDITIONAL INFORMATION
Apparently, Screen Grab calls ffmpeg with x11grab. Can this be changed to
libxcb?
