@reserved: padding field. Should be zeroed by applications. @order_hints: specifies the expected output order hint for each reference frame. This field corresponds to the OrderHints variable from the specification (section 5.9.2 "Uncompressed header syntax"). As such, this is only used for non-intra frames and ignored…

\brief Update the information for all device controls The V4L2Device class caches information about all controls supported by the device and exposes it through the controls() and controlInfo() functions. Control information may change at runtime, for instance when formats on a subdev are modified. When this occurs, th…

libcamera: base: regex: Fix preprocessor check clang has no `maybe-uninitialized` warning, therefore the suppression will generate a compiler error. This was probably hidden by the fact that `__SANITIZE_*__` macros have only been added to clang since llvm 22. Link: https://github.com/llvm/llvm-project/commit/568c23bbd…
