Lib[rem5|camera] to use everywhere

Hardware Librem 5

@galilley

Could we have a more developed tutorial ? I tried to use it on mobian and I couldnt reproduce your demos on mobian ?

I would like to understand what you have done properly

Is it possible ?

Thanks in advance for your answer and maybe your explanations

Sorry for the delay…

First of all, you could check is the DMABUF option enabled in the kernel:

$ zcat /proc/config.gz | grep DMABUF_HEAPS
CONFIG_DMABUF_HEAPS=y
CONFIG_DMABUF_HEAPS_CMA=y

If not, you need rebuild your kernel and next - patch and rebuild libcamera (you need to learn how to rebuild deb packages in chroot).
