Question: How does wait-images work?

[LGimmick]

Hi,

I tried to use --wait-images=5.0 for testing, but the application closes after merging the two initial images, regardless if I add images to the folder after a second or not. Do I have to use a specific directory? What am I doing wrong here?

You should give the names of all of the images on the command line, even if the files do not exist yet. The program will then wait for the the files to appear.

Thank you for the response.

You sure about that? 😄
I think I saw a verbose output, that contained the name of my output-image "out.jpg" as "aligned_out.jpg" eventhough all my input-images are bmp and numbered.

There are some internal temporary file names that are not saved unless --save-steps is given.

Hmm ok.
I still don't get it to work.

For testing I set --wait-images=50.0 and add 50 images-paths as files. And start the application after the first image is saved to a file. My expected behavior is, that the application (no matter what "waiting" exactly means) runs more or less 50s, if not all images are going to be created.
But the first two images will always be used for calculation and the application closes.

My thought is:
I created some sort of processing-pipeline for new images, therefore I have to wait a few images to create the mean-time it takes to save new images and set the wait-timer accordingly.

Can you attach a verbose log and the command line used?
For me it seems to work:

Thank you! I found a problem on my side within the pipeline 👍

It runs now, but if not all images are available it exits with "Error exit due to failed steps". Do all images have to be created?
