Subject: qv4l2: always set m_haveFramebufferSRGB to false Author: Hans Verkuil <hverkuil-ci...@xs4all.nl> Date: Tue Jul 23 15:39:16 2024 +0200 With Qt6 glEnable(GL_FRAMEBUFFER_SRGB) results in dark colors for some reason. It is fine with Qt5. Since qvidcap also ignores this (i.e. it never enables sRGB) I decided to do the same for qv4l2, so just set this to false. At some point qv4l2 should really switch to the qvidcap openGL code since it is getting to be quite a mess.
