1.4.0 - Saving AVIF file with YUV 420 setting => saved as YUV444

Merry christmas everyone!

I saved a PNG file to avif format with XnviewMP and could not open it with android phones and tablets.
Today I recognized, that XnviewMP saved the avif file with YUV 444, although I selected the YUV 420 format for saving.

Please check it and fix it. Thank you!

Here you can see the EXIF-Infos from the saved file.

This problem is supposed to be fixed in XnView MP 1.4.1. Please check and confirm the bug fix here.

The switch for YUV 420 color format works perfect.

Now it is possible to view images on Android 12 or newer devices.

There is only a problem with picture sizes with odd length or height, but it is a problem of the avif libraries in android 12 or newer!
XnViewMP does not produce the error. Android 12 can not handle picture sizes with odd height or length.

I hope they fix it in Android OS.
