Gphoto2 hangs on call to capture image with Sony A6000 #109

Hi,

Thank you for the incredible work on such a great library!

I've noticed a random hang issue with my Sony A6000 whenever I attempt to capture a series of photos in a row. After a random duration of time during which I call the camera to take pictures and download them to my computer, the following piece of code hangs:

gphoto2 --capture-image-and-download --filename image-number.jpg

It appears to occur randomly, and if I stop taking pictures and run gphoto2 --reset, the issue disappears (temporarily).

Is there any simple fix for this issue?

I was having exactly this same problem with a Sony A5100 (a very similar camera) and a Raspberry Pi. gphoto2 works fine with a Nikon and the Pi, and the Sony works fine with their own software under MS Windows.

After two frustrating weeks bug hunting I think I have stumbled on a solution. I had originally installed gphoto2 using gonzalo's script gphoto2-updater.sh on GitHub. Running gphoto2 -- version gave:

libgphoto2_port 0.12.0 iolibs: disk ptpip serial usb usbdiskdirect usbscsi, gcc, ltdl, USB, serial without locking

I then reinstalled libgphoto2_port using the Pi's Add / Remove software utility. gphoto2 --version now reports:

libgphoto2_port 0.12.0 gcc, ltdl, USB, serial without locking

Now everything appears to be working as it should. I need to test further, but I have run the camera for 12 hours, taking one exposure every minute, without mishap: something which I could never achieve before.

I don't have an explanation, and I would like to know if it works for you too.

I spoke too soon! Although the method detailed in my earlier post has significantly improved the mean-time-between-failure, it has not eliminated failures altogether.

BTW I think Issue 111 and Issue 80 are also referring to this same problem.

Hi, I have similar problem. My Sony a6000 has latest firmware 3.21. with gphoto2 --capture-image --interval 3 command it works great, but only for first 15 shots. At 16-th image it freezes. If i press the button on camera manually it takes several extra images but with big latency(much more then 3 seconds). Camera is in "remote PC" mode. Any ideas?
