Hello everyone, I'm looking into how to use the camera on the N900 when it is released, I would like to be able to write some code in Python if at all possible, but I guess I can move my app back to C if needs must.
Anyway, the camera will need to be focused, so I have been trawling through the kernel code and gstreamer source to try and work out how to do this, but I thought I may as well just ask as it may save me some time. I see there are ioctls for the ad5820 focus piezo controller which could be used (though I've not looked to see if there's a dev entry for that device yet), and Qole pointed out that the /dev/video0 device reports that it has v4l2 extended controls, including the ability to move the focus (though no mention of autofocus there afaict). I understand I should be able to adjust the focus through a gstreamer element such as camerabin or the photography interfaces, but ideally I'd like to do this from Python. Is v4l2camsrc linked to these btw? The other option (which means I don't have to wrap one of the gstreamer elements for Python) is to use the v4l2 extended control command ioctls directly on the /dev/video0 device. I'm assuming that should be possible anyway, certainly the Python part looks pretty straight forward (see e.g. FMRadio.py). While we're on the subject, I see some header files for what I presume is a Ti binary blob named isp_*.h. isp_af.h contains header information for autofocus functionality afaict. Is this functionality exposed to userspace anywhere? Looking through the package list, I came across a libgdigicam, might this be involved...? Anyway I'm going to keep experimenting with the above, but thought I'd see if anyone else has any bright ideas.
