Sorry, that was the wrong commit SHA (I looked in the wrong tree). I now have a fix for Qt6 pushed (even though it is not perfect). So please port the following three commits to the 1.28 branch: f09b2c091d90 ("qvidcap: fix core dump") e268a7229866 ("qv4l2: fix crash when disabling openGL") 69b3a7618cb5 ("qv4l2: always set m_haveFramebufferSRGB to false") With those committed you can make a new release that should work with Qt6. Apologies for not noticing before that Qt6 qv4l2 support was broken.
