[libcamera-devel] [RFC 0/4] prototype python bindings

[Tomi Valkeinen]

Hi,

Laurent asked me to send these to get discussions about the challenges
on the list (rather than in private chats...).

This is a prototype, RFC, hack, whatever you want to call it, but it
works for me for the small subset of features used in test.py.

The main patch "libcamera python bindings" has some questions/issues
listed in the description, and I've added comments to the code where I'm
not sure where to go.

There were no submodules in libcamera, so I used the same convention
I've used in kms++: ext/<submodule>. pybind11 could be added as
something that comes from the system (at least Ubuntu 20.04 has it), but
as it's header only, I think having it as a submodule is the easiest and
most manageable way to add it.
