test capture

test if capture perhaps already works:

gphoto2 --trigger-capture works gphoto2 --capture-image-and-download takes a photo but fails to move past that and gphoto2 --capture-preview fails with *** Error (-1: 'Unspecified error') ***.

Let me know if you'd like debug logs, USB traffic captured or any more info.

Thanks!

can you get debug output from the failed capture+download?
and also from the capture preview?

[trevorski]

OK, I've attached the debug output for both failed commands. One thing probably work noting is that the capture preview fails and seems to terminate the PTP session as the camera resumes its untethered state after the command returns.

Thanks a bunch & I'm excited for gphoto2 to support the Q3!

There is some weirdness, that the session is reported already open which led to the error.

0.059354 ptp_usb_getresp [usb.c:516] (0): PTP_OC 0x1015 receiving resp failed: PTP Session Not Open (0x2003)
0.059360 camera_capture_preview library.c:3988: 'ptp_getdevicepropvalue (params, PTP_DPC_SupportedStreams, &propval, PTP_DTC_UINT32)' failed: PTP Sessio
n Not Open (0x2003)

Currently the code does not seem to take the Leica specific paths as it did not know the USB id.

I have now added the USB id to libgphoto2, so one thing you can try is to update libgphoto2 to current GIT master, where I added the USB id?

[trevorski]

OK, I built gphoto2 against libgphoto2 built from master and it still seems to have the same (failing) behavior. Logs attached.

Thanks!

i added another fix, can you pull , rebuild and retest?

[trevorski]

gphoto2 --capture-preview works now! gphoto2 --capture-image-and-download still seems to fail/hang and I've attached the logs. Thanks!

So it waits for the "Capture COmplete" event, which does not arrive.

1. can you try if it works better if you do not use Dual JPG+DNG capture? e.g. single image either JPG or DNG?

2. can you change the line in camlibs/ptp2/library.c:

    {"Leica:Q3",                            0x1a98, 0x2376, PTP_CAP|PTP_CAP_PREVIEW},
   

to
{"Leica:Q3", 0x1a98, 0x2376, PTP_CAP|PTP_CAP_PREVIEW|PTP_NO_CAPTURE_COMPLETE},
and rebuild, this should also fix it.

1. My previous build was lost so I wasn't able to figure this out, but...

2. gphoto2 --capture-image-and-download now works with both dual DNG+JPG capture!

very good! :)
I think we solved the issues :)
