[libcamera-devel,v3,00/30] More misc Python patches

16071 mbox series

Hi,

This series just seems to grow...

Main changes to v2:
- Fixed, I hope, all the comments from Laurent
- --mode option for gen-py-controls.py
- Fixed the missing call to init_py_properties_generated()
- Added a bunch of new patches

I've moved the examples on top of all the other patches. I added
simple-cam.py, which is a copy of the .cpp version.

I still like the simple-capture.py and simple-continuous-capture.py,
though.

simple-capture.py is very simple, but it does all the work in a
single main function, and should be a good way to get familiar with the
concepts even if it's perhaps not useful in the real life.

simple-continuous-capture.py takes it further and makes it more
realistic, but also more complex as it adds a few functions, also
handles keyboard input, adds a class to store the context, etc.

simple-continuous-capture.py and simple-cam.py are somewhat different,
as the simple-cam.py follows the .cpp version as strictly as it can,
whereas in simple-continuous-capture.py we use the nice extra stuff from
Python.

I didn't really touch itest.py much. We can leave that out for the time
being, although I find myself using it often.
