The V4L2 code in the ffmpeg plugin uses V4L2_PIX_FMT_BGRA32 which was
only introduced in kernel headers 5.2, in upstream kernel commit
e25ec9141114c7124eeba09385e272dd76fbe617.
Fixes:
/home/thomas/buildroot/buildroot/outputs/qt/build/qt6multimedia-6.8.1/src/plugins/multimedia/ffmpeg/qv4l2camera.cpp:36:43: error: ‘V4L2_PIX_FMT_BGRA
32’ was not declared in this scope; did you mean ‘V4L2_PIX_FMT_BGR32’?

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
