Closed mikeev261 closed 1 year ago

mikeev261 commented 1 year ago

Describe the bug I have a Sony A7iii with Firmware 4.01 (latest version as of today). Not sure if the firmware is related. I'm getting the "Sorry, your camera does not support generic capture" error.

Name the camera USB PTP Class Camera usb:001,012

libgphoto2 and gphoto2 version gphoto2 2.5.20

This version of gphoto2 is using the following software versions and options: gphoto2 2.5.20 gcc, popt(m), exif, cdk, aa, jpeg, readline libgphoto2 2.5.22 all camlibs, gcc, ltdl, EXIF libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb1 usbdiskdirect usbscsi, gcc, ltdl, USB, serial without locking

To Reproduce

  1. Set Sony A7iii USB to MTP mode
  2. Connect to OctoPi via USB
  3. My command and output: 
    
gphoto2 --wait-event=3s --capture-image-and-download --debug --debug-logfile=debug.log
Waiting for 3 seconds for events from camera. Press Ctrl-C to abort.

Error Sorry, your camera does not support generic capture ERROR: Could not capture image. ERROR: Could not capture. Error (-6: 'Unsupported operation') 


4. [debug.log](https://github.com/gphoto/libgphoto2/files/11779518/debug.log)

Also: The "PC Remote" option in the camera menu doesn't work... just endlessly says "Connecting..." on the camera screen once I plug in the USB.

This is a very old version. (4+ years old)

You need to upgrade to a recent version, and you need to set the camera in PC Control mode.

Thanks, I did the following:

Updated to libgphoto to 2.5.27 and gphoto2 to 2.5.27. I tried downloading and compiling the 2.5.30 and 2.5.28 packages, respectively. libgphoto compiled, and gphoto2 failed with this same error: https://github.com/gphoto/gphoto2/issues/479. So I decided to stick with 2.5.27/2.5.27, as that's the latest managed version pair that I can find via apt-get.

And now I'm seeing: 

gphoto2 --auto-detect
Model                          Port
----------------------------------------------------------
Sony Alpha-A7 III (PC Control) usb:001,00

However, the PC control mode still shows "Connecting...", and when I try --capture-image the console sits for ~10 seconds, and eventually says: 

ERROR: Could not capture image.
ERROR: Could not capture.

If I do --capture-image a SECOND time, it then works (and it clears the "Connecting..." screen on the camera).

Newer sony cameras need a bit of waiting in front, so I added this in code now. This would avoid the wait-event. it is in current GIT.
