Stitching fails after upgrading Theta Z1 Firmware

[theOpheliart]

After upgrading the firmware on my Theta Z1 to the latest version, I no longer get an EXR file. The command line shows the following error:

Bracket 0: Exception - Command '['C://Program Files//Luminance HDR//v.2.6.0//luminance-hdr-cli.exe', '-l', 'C:/Users/User/Pictures/ricoh-tests/raw-test/lzw/Merged/exr/merged_000.exr', '--tmo', 'reinhard05', '-g', '2.2', '-b', '-q', '98', '-o', 'C:/Users/User/Pictures/ricoh-tests/raw-test/lzw/Merged/jpg/merged_000.jpg']' returned non-zero exit status 4294967295.

The log files show the following error:

STDERR:

My proccess is:

1. Batch Convert the DNG files to tiff in Affinity Photo
2. Convert the Dual Fisheye to Equirectangular in the Ricoh Theta Software (leaving this step out does not change anything)
3. Run the Stitcher

The only thing I actually changed from the last time I did this a few days ago was upgrading the firmware of my 360 camera. So I assume something is different about the image files, but I lack the knowledge to determine what exactly.

If you can supply a zip file that contains both new and old firmware versions, I can look into it for you. Keep in mind this is open source software, you are also free to investigate and resolve the issue yourself and then submit a pull-request so that others may also benefit :)

Thanks for the quick response. I wish I could resolve this issue myself, but unfortunately my coding knowledge is to limited. Now from the error that is thrown I assume that Blender has some kind of problem reading the new tiff files and I am not sure what that could be. When I open the blend files your script creates, they are read normally, but just as the error suggests, there is no link created between the image node and the rest of the setup. Interestingly enough stitching works if I create the photos with the old app. So for myself I currently have a workaround, but it would still be cool, if this amazing program could still be made a bit more robust with this.
I've attached a zip for you.

Looking at the error, it seems to be caused inside of blender, while merging the tifs into the exr.

AttributeError: 'NoneType' object has no attribute 'outputs'

this points to an error trying to connect nodes, which most often caused by blenders node python api changing, if i had to guess its caused by using an unsupported blender version.

@theOpheliart what blender version did you use?

I recommend you try the latest version of Merge Master with one of the supported blender versions (either 4.5 or 5.1 LTS)

At the moment i cannot reproduce the issue.
