XnView Software

Thank you first for your hard work and release of version 1.6.0!

1. File menu => save as => avif file format

I opened a png file and saved it to the avif format (different compression settings tested e.g. Quality 80%, Format 420, Speed =5).

Error-Message: An error occurred during saving

In the german translation the program says: 'File could not be renamed'.
The german translation of the same error is different!
Maybe it helps you to faster find the error. Thank you!

hm, I have issues with other formats, but could not reproduce error with AVIF (tried different settings)

If you have installed the setup, please rename libde265.dll into de265.dll

I did a fresh install of the XnviewMP.exe and get the error message.
Now I tried the xnviewmp.zip file and avif file saving works fine!

You are right. It is a problem of the wrong filename of the x265 library.
I renamed it to de265.dll and now it works fine.

Thank you!
