Option to set effort when converting to avif #11

Closed rohitghali closed 1 year ago

rohitghali commented 1 year ago

How do I set effort when converting files to avif?

gen2brain commented 1 year ago

You can't, you can only set quality effort and lossless options, as per libheif docs https://pkg.go.dev/github.com/strukturag/libheif@v1.14.0/go/heif#EncodeFromImage. You can see some comparisons with JPEG quality here https://www.industrialempathy.com/posts/avif-webp-quality-settings/.

image Like in the image above. What's the effort option there?

gen2brain commented 1 year ago

There is no option. Libheif doesn't expose that option, everything is done with quality.

ok.
