Phoronix: Mozilla Firefox Appears Ready To Enable AVIF Image Handling Support By Default

It looks like Mozilla Firefox very soon will be enabling support for AVIF as the image format based on AV1 video coding...

Does imagemagick support avif? I tried converting something to it (Debian testing) but it's changing the file.

[FONT=monospace][COLOR=#000000]convert -verbose test.jpg test.avif [/COLOR]
test.jpg JPEG 374x423 374x423+0+0 8-bit sRGB 67756B 0.010u 0:00.006
test.jpg=>test.avif JPEG 374x423 374x423+0+0 8-bit sRGB 68217B 0.000u 0:00.006[/FONT]

That's weird. They dragged on with WebP support for five years before finally enabling it, now with AV1F they are almost rushing.

The ImageMagick website lists its supported formats, but AVIF is not listed.
The GraphicsMagick (a fork) website lists its supported formats, but doesn't include AVIF either.

And now Google is experimenting with WebP2, a successor to WebP.

A few months ago it didn't work, but now it works for me:

test.jpg JPEG 6000x4000 6000x4000+0+0 8-bit sRGB 5640540B 0.200u 0:00.206
test.jpg=>test.avif JPEG 6000x4000 6000x4000+0+0 8-bit sRGB 1.57753MiB 93.430u 0:28.035
$ exiv2 test.avif
File name : test.avif
File size : 1654164 Bytes
MIME type : video/quicktime
Image size : 0 x 0

It used 28 seconds and 4600 MB RAM on Ryzen 2600.
ImageMagick 7.0.10-52 Q16 x86_64 2020-12-19
aom 2.0.1
libheif 1.10.0
If you cannot update imagemagick, you can use avifenc from 'libavif' (or 'libavif-bin') package.
I didn't found know how to losslessly encode using imagemagick, I only know

avifenc -j 12 -s 0 -l test.png test.avif

(-j is number of threads, -l is lossless, lowest -s = 0 = longest encoding but the best size).
jpg -> webp:

avifenc -j 12 -s 0 --min 0....63 --max 0....63 test.jpg test.avif

(min and max acceptable qualities, less is better).
Also Firefox (latest version=84) still doesn't support both lossless and lossy transparent AVIF (wrong colors): probably bug https://bugzilla.mozilla.org/show_bug.cgi?id=1682677
So there will be nothing better for lossless 8-bit-per-color images than

cwebp -mt -q 100 -m 6 -lossless on test.png test.webp

for a long time (lossy webp even at -q 100 damages red color) . Also lossless webp takes less space (and encoding time and RAM, but no HDR) than lossless avif. The lowest webp size is acheived by having 3 flags "-q 100 -m 6 -lossless on", some people (e.g. https://docs.google.com/spreadsheets...KQM/edit#gid=0 ) compared lossless avif and png not using all of them.

You need compile imagemagic with libheif. Then avif should be supported.

avifs still dont load right (if at all) on the nightly... its usually just the first image in the sequence while chrome had been able to for months now. but thats the usual with mozilla now

[bug77]

It's great we can show the format, but who produces AVIF images right now?

And now Google is experimenting with WebP2, a successor to WebP.

Google doesn't even support WebP across all of their own products yet. You can't import WebP images into Google Slides, for example.
