Poor compression from jpeg to avif via code about govips HOT 5 CLOSED

Hey @dAvagimyan, can you check what AVIF library your libvips build is built against, and check the latest libvips documentation for the parameters you can give? Sometimes we have stale parameters as libvips and/or the avif library libvips uses are updated and the govips API is out of date.

from govips.

vips version:
vips-8.15.1

 heif-enc --list-encoders
HEIC encoders:
AVIF encoders:
- aom = AOMedia Project AV1 Encoder 3.8.2-377-g04d6253 [default]
- svt = SVT-AV1 encoder v1.8.0
JPEG encoders:
- jpeg = libjpeg-turbo 1.2.90 (libjpeg 6.2) [default]
JPEG 2000 encoders:
Uncompressed encoders:
- uncompressed = uncompressed [default]

Yes, could you look at libvips documentation for the parameters you can give? Sometimes the libvips backend has changed or the parameters and govips needs to be updated. Libvips has an impressive speed of development and backend libraries differ even between environments, it's very challenging to maintain govips APIs

Thanks, I'll take a look. But I tried got it behavior in differents os. (centos 7, ubuntu, also macos)

Everything is ok! Thanks a lot. Avif conversion in console using quality 50%.
