Failed to convert to avif format

[phars]

As a Linux Mint user, I downloaded the latest version of XnConvert. I converted a PNG image to AVIF and received an error message saying "Not an image." However, it worked with any format other than AVIF.
Even when I converted from XnView, it didn't work. It just created a white file with a size of zero bits.
I tried the same thing with a different program, and it worked.
I hope for a quick response.]

only libheif/libheif-dev is needed. which libheif.so do you have?

only libheif/libheif-dev is needed. which libheif.so do you have?

libheif.so.1 (libc6,x86-64) => /lib/x86_64-linux-gnu/libheif.so.1
libheif.so (libc6,x86-64) => /lib/x86_64-linux-gnu/libheif.so

Is there something missing?

I am using the latest version of Linux Mint and yet I still encounter the problem. The strange thing is that I did not encounter this problem in Windows.
In Linux, when I convert an image to this avif format, it gives me an error message but creates images with a size of 0 bytes.

What should I do now? ;-;

i've installed latest Mint, and right you need to install libheif-plugin*

Excellent and what is the best way to install and ensure its operation?

I have converted the image to heic format manually using this command

Code: Select all

heif-enc input.jpg -o output.heic

It worked and the same thing happened with avif
But it did not work with the program
