A lot of errors with a Canon 350D #1

Closed kasperkamperman closed 9 years ago

kasperkamperman commented 9 years ago

I can't get the image qualities. I can take a picture (camera clicks and stores indeed a picture on the memorycard). However I can't see the picture.

My code (slightly modified basic example to debug more): https://gist.github.com/kasperkamperman/c616cf0ce61338e9ca10

Printed in the console when starting:

No library found for edsdk.utils.CanonConstants
Java Architecture: x86 - Using EDSDK DLL: EDSDK/Dll/EDSDK.dll
edsdk-processing 1.0.3 by Hansi Raber http://asdfg.me
Running on Java 1.7.0_40/Oracle Corporation (32bit)
print cam: edsdk.processing.ProcessingCanonCamera@46b78d
print Array image qualities: 
An error occurred while getting detailed kEdsPropID_ImageQuality data (error 96: EDS_ERR_INVALID_PARAMETER - Invalid Function Parameter)
null

What is remarkable is that the camera is found. But that the array with image qualities returns null.

When I press the spacebar to take a picture:

Could not check live view status: An error occurred while getting kEdsPropID_Evf_Mode data (error 7: EDS_ERR_NOT_SUPPORTED - Not Supported)

I hope you have any ideas. Are there some version conflicts, is my camera too old? I know the 350D doesn't have live preview. But that is not necessary to store an image isn't it?

Any help is appreciated.

I've tested with a Canon 600D and with that camera it seems to work fine (although live view is really slow).

yea, you get only roughly 6-8 frames/second. that's expected :)
