[Bug 186574] New: Directly download and preview shot

[paracetamolo]

https://bugs.kde.org/show_bug.cgi?id=186574

           Summary: Directly download and preview shot
           Product: digikam
           Version: unspecified
          Platform: unspecified
        OS/Version: unspecified
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
        AssignedTo: [hidden email]
        ReportedBy: [hidden email]


Version:            (using KDE 4.2.1)

It will be extremely useful to connect your camera to digikam, and while taking
pictures to see the image in full screen on your pc.
Usage scenario: I'm taking picture in a studio and I want to instantly see my
shots in full resolution in my pc screen and not in the little camera screen.
Similar feature is in 'digital photo professional' by Canon.

Possible with cameras that support it (currently mostly Nikon and Canon DSLRs).


Call
int
gp_camera_wait_for_event (Camera *camera, int timeout,
                          CameraEventType *eventtype, void **eventdata,
                          GPContext *context)

timeout is in 1/1000s, eventtype GP_EVENT_FILE_ADDED is interesting, in that
case eventdata points to a CameraFilePath* structure,
path->folder and path->name  specify the newly added image, download it as
usual.

CameraEventType etype;
void *data;

if (GP_OK == gp_camera_wait_for_event (camera, 1000, &etype, &data, context)) {
       if (etype == GP_EVENT_FILE_ADDED) {
            CameraFilePath *xpath = data;

            ... download and use xpath->folder, xpath->name

        }


}

Thanks Marcus !

But if i'm not too wrong, i have already implemented this feature one year ago
when i have started to port digiKam to KDE4...

The option is from Camera/Capture menu in camera interface (digiKam 0.10.0
only).

I have tested this with my old Olympus C3000z, now dead (:=))). So i cannot
test anymore.

Marco, can you test with your camera if it work fine for you ?

Thanks in advance

That's great!
Tested on 0.10.0 with a canon EOS 350D. Basically it work but it is buggy.
As long as I press Capture the camera start to shoot in a loop and a menu
appears with help, capture, cancel. When I press capture the camera stops
shooting and the acquisition process start. After a while it shows a icons with
a question mark and if I press on it says failed to retrieve files from camera.
Despite this if I reconnect the camera it shows the picture (only one)
previously taken.
Problems:
-the camera should shoot (one time) only when I press capture in the dialog.
-the acquisition should show the pictures.
-despite having done many shot when I reconnect I have a single picture
I tried with this configuration: empty CF inserted in the camera that was set
to 'pc connection'.
I also tried with the camera set to Print/PTP connection but the capture button
was disabled.
This feature is really great and we are a step away from making it work :P

http://gphoto.org/doc/remote/ has a manual provided list.

the cameras that support capture report this via their CameraAbilities

abilities->operations & GP_OPERATION_CAPTURE_IMAGE to test

Marcus,

There is a way to test capture mode without to use a real camera device, for
example with a test driver from Gphoto2 (emulation) ?

There are three enhancement requests for this in the database:
Bug 186574
Bug 207936
Bug 258227

Should they be marked as duplicates of only one ?

Git commit 589228bc057710cc00f9785e1f31b23d21264c38 by Teemu Rytilahti.
Committed on 22/12/2013 at 18:34.
Pushed by rytilahti into branch 'master'.

Don't spam the camera with preview requests, even if capturing is possible, but
liveview is not. Done by checking the existence of GP_OPERATION_CAPTURE_PREVIEW
flag.
