PTP Device Busy after --capture-movie #594

Open linus-tls opened 1 year ago

linus-tls commented 1 year ago

Describe the bug After I run gphoto2 --stdout --capture-movie, Im unable to capture any images.

gphoto2 --capture-image-and-download --filename=outputfile.jpeg --debug --debug-logfile=my-logfile.txt outputs the following error: *** Error *** Canon EOS Full-Press failed (0x2019: PTP Device Busy) ERROR: Could not capture image. ERROR: Could not capture. *** Error (-110: 'I/O in progress') ***

Capturing images works normally before I run --capture-movie.

Name the camera Canon EOS 250D

libgphoto2 and gphoto2 version gphoto2 2.5.27 libgphoto2 2.5.27 libgphoto2_port 0.12.0 Ubuntu 22.04.2 LTS

To Reproduce

  1. gphoto2 --stdout --capture-movie
  2. Exit movie capture
  3. gphoto2 --capture-image-and-download --filename=outputfile.jpeg --debug --debug-logfile=my-logfile.txt

my-logfile.txt

Please make sure you have latest libgphoto2 2.5.30 , it is worth trying to update.

how do you exit movie capture? with ctrl-c ?

linus-tls commented 1 year ago

Will update and test again. Yes, ctrl + c.

So I was having a similar issue that drove me up the wall for a few hours. My code worked for a whole day, then it stopped working all of a sudden, and it started returning this error:

*** Error *** Canon EOS Full-Press failed (0x2019: PTP Device Busy) ERROR: Could not capture image. ERROR: Could not capture. *** Error (-110: 'I/O in progress') ***

But I think what was happening was it was trying to auto-focus with my lens, so I lifted it off the ground where it was probably trying to take a blurry photo. I believe it would send a command to the camera to take a photo, the camera would try to focus, and unable to do it, it would send back an error that it couldn't snap a photo. Try pointing your camera at a big empty room or yourself and see how it goes.?
