XnView Software

This may be an issue with HEIC images taken on iOS 18 but I wouldn't know.

In version v1.7.2 and v1.8.0 of XNView MP, when browsing in Details mode, only Model data from a few files could be read and displayed and the rest are showing empty, even when switching to ExifTool at the bottom left panel, Camera Model name are present for those files.

LibHeif is updated to v1.18.2 and it seems the issue is now fixed but XNView is still using v1.17.6 in version 1.8.0 so that may be the cause, I am not sure. Wait… could this be an issue of ExifTool as well? @_@

Here's an example of the image not displaying camera model name:

yes confirmed. libheif 1.17.6 can't get metadata on this file. I waiting 1.80.0 version on vcpkg

In fact, I tried and compiled libheif v1.18.2 with vcpkg but the performance in XNView MP is the worst even with multithreading feature, I tried both x86 and x64 versions of the compiled DLLs but the performance was just...
Consequently I never waited for a folder of some 3000-ish files to be read and loaded to see if the Model can be properly displayed.

I didn't know what went wrong Or maybe you were using different parameters when compiling.
