Bug 492696

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

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?
