Re: Error when downloading image directly from memory card

Hi,

It is actually a more interesting problem...

If we switch the camera to application mode, it no longer returns a filesystem.

$ gphoto2 --set-config applicationmode=1 --wait-event=1s -L
Waiting for 1 seconds for events from camera. Press Ctrl-C to abort.           
UNKNOWN PTP StoreRemoved, Param1 00010001
There is no file in folder '/'.
$ 

The storage is "semi visible", e.g. if we access the filehandle from
the "changed" event, it can be accessed.

But as the filesystem does not see the storage in the storageids index, it cannot find the right path.


I need to think a bit on how to handle this... :/


(A workaround would be on receipt of "file changed" to switch off
 application mode, wait for the StoreAdded event, get the file, switch
 on application mode, and go back to polling.)

Ciao, Marcus
