Error in capture-image for Canon 5D Mark IV

[francophongvu]

I installed libgphoto2 on Pi, connect Canon camera and simply run the example: capture-image.py

I received the error:

WARNING: gphoto2: (gp_port_usb_close [libusb.c:325]) Invalid parameters: 'port && port->pl->dh' is NULL/FALSE.

Install an image viewer known to xdg-open, or remove the line subprocess.call(['xdg-open', target]) from your copy of the example script.

The remaining warning messages are normal and can be ignored.

Thanks for quick reply,

I tried to remove the line subprocess.call(['xdg-open', target]) then it seems no error, but there're no file saved in camera (ran command linegphoto2 --list-files)

There is no file in folder '/'.
There is no file in folder '/store_00010001'. There is no file in folder '/store_00010001/DCIM'. There is no file in folder '/store_00010001/DCIM/100EOS5D'. There is no file in folder '/store_00010001/MISC'.

Sorry, I am new with this library

You camera is set to record to RAM, not to its memory card, which is why the file name is capt0000.jpg. Set the capture target to "memory card" and you should then capture files with names like DSCN1234.JPG.

Hi, just a stupid question: is it possible to set the capture target to "memory card" by python code?

Before I used the command line:

command = ["sudo","gphoto2","--set-config","manualfocusdrive=6","--set-config","capturetarget=1","--capture-image"]
call(command)

[jim-easterbrook]

You could try the set-capture-target.py example.
