[dsausage]

just simply convert any type to AVIF,
tried disable all options and different settings, all failed

win11 up to date,

and ZIP version of XnviewMP

there is save error and sometimes crash when you trying to save large image (~18k) at certain AVIF settings

what are the output dimensions of your images?
same issue if you save image as AVIF from Viewer via File>Save as ?

also show screenshots:
- Batch convert > Actions (if you have any action there)
- Batch convert > Output tab
- format's 'Write settings' (press 'Settings' button in Batch convert > Output tab - Format group)

Thanks for reply!

> what are the output dimensions of your images?
if you asking the original img, it's 1300x1000x24 49.09KB
if you asking the output result, it's none file output.

Having the same issue

I might found the problem is
I have an old-version MP, It has plugins\dav1d.dll
It doesn't exist in 1.11.2
I put it in plugins of 1.11.2 and the batch-convert works again.

FYI

I have an old-version MP, It has plugins\dav1d.dll

you have it in main folder, i've tried on Win11 and no problem

[dsausage]

Thx for the info, it's newer version in main folder
but in my case I must move it to plugin else it won''t work tho.

I can confirm the batch conversion error with the avif file format under Windows 11 (latest updates).
I did a clean install in a fresh directory to check this problem.

XnViewMP can save pictures in avif format with the 'save as' dialog. It works correctly.
But batch conversion does not work. The log file says saving 'test.avif failed'.

The successful solution is to move the dav1d.dll to plugins subfolder to prevent problems.

I also recognized, that there are 2 dll files with the same version and filesize, but different names.

I have a dav1d.dll and libdav1d.dll. Both have version 1.53.
Maybe different librarys need them with different names? E.g. ffmpeg or other libs?

---

Another strange thing is the avif filesize with the batch conversion and save as dialog.
Maybe both use different avif encoders? I get totally different filesizes with 100 kb dfiference.

Thanks to your detailed description I can reproduce the problem.
