[EOS 1000D] Preview does not work in auto mode (PTP Operation Not Supported (0x2005)) #283

Closed larsf96 closed 4 years ago

larsf96 commented 4 years ago

Describe the bug I've tried to capture a preview image with --capture-preview on my EOS1000D. For some reasons, this does not work when the camera is in automatic mode. When switching the camera to Tv, Av or P modus, i can get preview images without any problem. When I then switch back to the automatic mode, the first caputure of --capture-preview works as excpected, but the second try fails. I've attached some log files. The following errors are always showing up for these attempts:

  1. PTP Operation Not Supported (0x2005) 2.PTP Device Busy (0x2019)

Is the preview supposed to work in automatic mode? notworking.txt working_first_automatic_mode.txt working_manual_mode.txt

Name the camera Canon EOS 1000D

Any ideas if this can be fixed somehow?

msmeissn commented 4 years ago

The PTP Operation Not Supported (0x2005) related to "AfCancel" ... there was a check missing, which is fixed in libgphoto2 2.5.24 now.

For the other its not so clear. need to rty with my EOS 1000D

I tried with my EOS 1000D with more current libgphoto2 -> no problems to get liveview in either mode.

Please update to 2.5.24. ;)

larsf96 commented 4 years ago

I've upgraded libgphoto to 2.5.24. The PTP Operation Not Supported (0x2005) error seems to be fixed, but now I get a "Unidentifiable Error". I've attached the logs debug.txt

I tried back and forth now with my EOS 1000D, but no luck.

Also the camera itself does not go into liveview mode when I press the "Set" button in the automatic modes.

I now looked at the manual of the EOS1000D

https://www.canon-europe.com/support/consumer_products/products/cameras/digital_slr/eos_1000d.html?type=manuals&language=en

In section 5 "Live View" it indicates this is only possible in the P-TV-AV-M-Adep modes.

So this is a camera limitation, and we cannot do much about that.
