i have been working with Marcus Meissner to include Panasonic Lumix cameras in libgphoto2 over wifi/http. (github.com/gphoto/libgphoto2/tree/lumix) this is starting to work well form gphoto2 CLI however the --auto-detect option is not yet avail since libgphoto does need the IP address of the camera to connect to it. so at the moment the CLI options for gphoto2 are:
gphoto2 --port ip:192.168.1.14 --camera "Panasonic LumixGSeries"

Is there a way to configure the indi gphoto driver to include these options at startup instead of relying on the --auto-detect?

Thanks

Thank you for your work! Please check out gphoto_open function and see how we can use libgphoto2 to communicate over IP instead of USB. Maybe we can reuse the
shutter_release_port
? That is, we detect if the value in there is an IP address (either ipv4 or ipv6) and then make the appropriate call for libgphoto2.

Hi Jaseem,

it has been a while since i looked at the code. work got in the way...
Anyway i did install the dev stack of indi and 3rdparty drivers in order to see what can be done with the gphoto_open as you suggested. however I am not sure how much of the args are passed and i cannot make much sense of some of what is happening...

for instance:
1)
gphoto2 --list-ports
returns
Devices found: 4
Path                             Description
--------------------------------------------------------------
ptpip:                           PTP/IP Connection               
ip:                              IP Connection                   
serial:/dev/ttyS0                Serial Port 0                   
serial:                          Serial Port Device

this would lead me to believe that a port "ip:192.168.1.12" in the config panel should be passed on correctly to the driver but i cannot get it to pass .

2) i cannot see how
--camera "Panasonic LumixGseries"
can be passed as an arg to the driver.
3) also i do not get how gphoto_ccd and gphoto_driver are connected.
4) i tried to create lumix entry in the indi_gphoto_xml.cmake which does appear correctly on the ksars camera menu but fails at launch.
5) it seems that none of the attempts i made in modding the gphoto_open led to any consideration in the execution almost as if the original driver was called but i did change the target from /usr/local to /usr/ ...

anyway long one to ask for you to look at this probably simple feat for you but quite complex for me. I would be quite keen to go back and forth with you if you cannot test the actual driver against the lumix cameras...

Thanks in advance

Robert

Hello Robert,

The process is more involved than that. Edit line 1579 in gphoto_driver.cpp and change it to something like this:
index = gp_port_info_list_lookup_path(portinfolist, "ip:192.168.1.12");

or make that "ptpip:192.168.1.12" .. then compile and install. Then run the indi_gphoto_ccd driver and put a break point at that link (#1579) and press Connect in the driver. It should take you there. See if the rest of the code works fine or if returns any error.

If it is indeed as simple as this, then we can add an IP address property to the driver and if non-empty then we use it there.

Hello fellow community :)

I know this is an old thread, but I just landed here searching for my problem.

If anyone is having problems taking images with a Nikon Z-series, and restarting everything does not help, there is a nice little detail about the mirrorless Nikons. When you unplug the power while the camera is on, the camera closes the mechanical front curtain (I have an external power-supply instead of the battery). The front curtain stays closed after the next power-on until you manually press the release button on the camera. While the mechanical shutter is closed the camera will not take any pictures or open the front curtain from software commands. You only recognize this in EKOS from capture errors and permanent retries.

A nice side effect is, that you protect your sensor from dust when you unplug the power after an imaging session :)

I control my DSLR D7000 with my Macbook
My macbook is at home
My telescope outside.
I use a Belkin Home Base F5L049ea to connect SUB over IP my devices (DSLR + Mount)
I telescope is a Celestron C8 AS-GT.
I tried to used Ekos to capture :
- it works when DSLR is directly connected on USB of my Mac.
But it doesn’t work when I used my BELKIN USB over IP.
I tried with Smart Shooter 4 (in Trial). It works well.
By the way, Ekos works fine to control my Celestron C8 AS-GT mount.

I don’t know why it is not working on Ekos.
Do you use USB over IP with DSLR ? do you have to choose a special configuration for DSLR when using a device USB over IP between computer and DSLR ?

<strong>Hi Robert, Jasem

I pulled the code for the libgphoto2 (lumix) library and indi gphoto driver a few months ago, and after some learning (!) and a few modifications to both, I now have ekos/indi working with my Lumix GF7.
I'm running indi on a raspberry pi 4, and I can stream the live view, capture images in both raw and jpeg with my camera connected to my wifi lan.

Thanks for a great effort in pulling all this together!

I still have a couple of bugs to iron out before I commit the code, but I thought I would let you know in case someone else is working on this too.

The changes will need to be in both libgphoto2 and indi gphoto driver for this to work, and this is the first time I've committed anything to either of these projects so please let me know if there's anything I should be aware of.

Thanks
Mike</strong>

Chiming in to attempt to learn/understand a bit better. I'm both a Nikon full frame and Panasonic owner. I have both a GH4 and GH5s. I've been experimenting with the GH4 directly attached to to a Pi running ekos using gphoto. Much of this works on the GH4 but all that functions on the GH5s is firing the shutter which I assume is a fairly generic bit of functionality. I see there has been some development work on getting the Panasonic cameras functioning over wifi which is where I'm a bit confused. Why wifi? Isn't it much more straightforward to connect the cameras via USB as apparently. Is there something specific about the functionality of the GH5s that prevents it being supported via USB in gphoto? Could someone possibly clear up my confusion here and set me straight? I'd really like to use my M4/3 cameras to get a little extra focal length on my widefield scopes. The Nikon full frames are great but I'd just like the extra flexibility of using both.

The Lumix GF series cameras don't support USB tethering, as far as I know. Later models have WiFI for use with a smartphone App and cloud services.
Sorry I can't help with your GH5s question.
