V4L2_CTRL_TYPE_U32 is a control compound type. /* Compound types are >= 0x0100 */ V4L2_CTRL_COMPOUND_TYPES = 0x0100, V4L2_CTRL_TYPE_U8 = 0x0100, V4L2_CTRL_TYPE_U16 = 0x0101, V4L2_CTRL_TYPE_U32 = 0x0102, V4L2_CTRL_TYPE_AREA = 0x0106, This means it carries a payload and needs to be handled like V4L2_CTRL_TYPE_U8 is, specifcially when it comes to parsing it from the V4L2 interface into a libcamera control. I'm surprised you don't hit this in V4L2Device::getControls() if (info.flags & V4L2_CTRL_FLAG_HAS_PAYLOAD) { ControlType type; switch (info.type) { case V4L2_CTRL_TYPE_U8: type = ControlTypeByte; break;
