Unable to load Canon RP #81

Closed sharon92 closed 6 months ago

sharon92 commented 6 months ago

I get the following error for canon EOS Rp connected via OTG:

cppcms::json::bad_cast: invalid type error converting from null to number

Any chance I am doing something wrong?

I am using Android 12 on realme 7 pro.

Looking forward to use the app!

1st of all make sure you set the camera to manual mode "M".

https://github.com/artyom-beilis/OpenLiveStacker/wiki/Open-Live-Stacker-Manual#dslrgphoto2

Once you open camera it should make a single shot to get frame format information.

artyom-beilis commented 6 months ago

If it does not solve do following:

  1. close app, disconnect camera
  2. restart app
  3. check "enable camera debugging"
  4. connect DSLR in M mode
  5. open camera with gphoto and open the camera
  6. select format if appears, press stream

Now get the logs from: Android/media/org.openlivestacker/OpenLiveStacker/debug/

This is the key:

GP2 LOG:gp_port_set_error [gphoto2-port.c:1191]:Could not claim interface 0 (Device or resource busy). Make sure no other program (gvfs-gphoto2-volume-monitor) or kernel module (such as sdc2xx, stv680, spca50x) is using the device and you have read/write access to the device.

Looks like either something else uses the camera can it be auto start by other app?

sharon92 commented 6 months ago

@artyom-beilis there is a pop up message which asks if I should allow the camera to access my storage. I ignored it this time and now it works!

artyom-beilis commented 6 months ago

Excellent. I think I need to add this to wiki!

sharon92 commented 6 months ago

@artyom-beilis thanks I am really excited to test it on the dark sky mountains next week!

artyom-beilis commented 6 months ago

Documentation is updated: https://github.com/artyom-beilis/OpenLiveStacker/wiki/Open-Live-Stacker-Manual#dslrgphoto2

Thanks for detailed report!

I strongly recommend to get used to the app before you get to dark location - so you know how to use it, set controls properly use stacking configuration, histogram, etc.

Every stacking software has its learning curve

sharon92 commented 6 months ago

Yes I have been going through it. Does it require tracking equipment? From the docs it seems so, I was hoping that OLS also aligns the images.

artyom-beilis commented 6 months ago

I was hoping that OLS also aligns the images.

It does. And you don't have to use tracking mount. But of course it limits max exposure time you can use. But more than feasable with short focal lengths or high binning.

sharon92 commented 6 months ago

Cool! I will try 10s exposures over 1 hour with 35mm lens :) Will try testing it tonight in the city lights to get the feel :)
