C'est l'occasion de passer à un format d'image efficace : #AVIF. LaFibre.info bascule progressivement sur ce format d'images très efficace : https://lafibre.info/evolution/images-avif-sur-lafibre-info/
Since it is kinda new, in comparison, there is room for improvements and better use of hardware accelerating regarding decoding: https://avifstudio.com/blogs/faq/evaluating-avif-decoding-speed/
Still, the smaller size makes download quicker and, of course, free up bandwidth on internet. So is compensating.
However, the encoding speed seems to already be there: https://avifstudio.com/blogs/faq/avif-encoding-speed/
Thanks for making me look up more about #AVIF. It fits very well - as in open - with things I'm working on
@m0xee @mirabilos
My vote would be for #AVIF. It seems to be the best format for low-fidelity, low-file-size, high-compression images for social media.
libaom, the reference AV1 encoder, has a new release: https://aomedia.googlesource.com/aom/+/refs/tags/v3.12.0
I’m super happy to have been featured in the release credits, and even happier that our image quality improvements designed for AVIF have come to libaom from SVT-AV1-PSY. For those looking to deliver the best quality per bit for images on the Web, hopefully the new `--tune iq` will help you out.
Interesting, it looks like #snac2 serves up both format, but #GtS only natively serves up the #WebP, and gives me a link to the #avif.
Let's see what Mastodon does...
Also, corporations offloading bandwidth costs is a valid criticism, but I do want to reduce bandwidth (and storage) costs for my instance owners.
One reason I use a pixelfed instance is so that I do not overwhelm my main instance's storage.
But lately I've taken to just hyper-compressing my images with WebP (and reducing them down to a maximum of 2048 pixels on either axis) instead of posting to PixelFed. ImagePipe is a great FOSS app for automating this.
For the record, I'd much rather use #AVIF over #WebP, but #GoToSocial doesn't support it yet.
“JPEG VS AVIF - The Battle of Compression” by kliksphilip

> In this super thorough study I test one single HD image and come to vast sweeping conclusions about JPEG XL and AVIF. But that's still one image comparison more than most people do! :)
I love the idea of JPEG XL “creating a sandwich of superiority around the middling AVIF”!

@jbowen For online viewing? Absolutely. Send me the smallest identical version of what you’ve got. #JPEGXL and #AVIF are fine, too (and even #HEIC for the Apple crowd; Safari will ask for it if it exists).
For saving, no. Give me a JPEG with all your metadata, at least until desktop OSes start treating these newer formats equally.
Un site web qui a des images en #WebP ou #AVIF et votre vieux logiciel refuse ces nouveaux formats ?
Convertissez les images en un clic en #PNG / #JPEG.
J'ai testé toutes les extensions disponibles pour Firefox / Chrome / Edge: https://lafibre.info/navigateurs/extension-convertir-webp/

GIMP 3.0.0 RC est disponible !
Parmi les améliorations par rapport à GIMP 2.10 : les exports au format #AVIF.
⇒ https://lafibre.info/logiciel/gimp-3-0-0-est-disponible/
Sous-échantillonnage 4:4:4, données Exif et XMP: AVIF devient vraiment utilisable avec #GIMP 3.
The AVIF image format is quite nice.
* comte.png 83KiB → comte.avif 31KiB
* factotum.png 84KiB → factotum.avif 38KiB
* procureur.png 74KiB → procureur.avif 31KiB
A real page like https://mnt.io/series/reactive-programming-in-rust/observability/ decreases from 336KiB to 285KiB (-51KiB).
Not negligible at all.
Thanks @GIMP for native support :-].
Publico otro artículo expandiendo el anterior: «Crear previa o image miniatura de video en Django».
Cuando se sube un vídeo a un servidor, es común que se quiera mostrar una previa. Es útil para enseñar una vistazo rápido del vídeo antes de reproducirlo. En HTML se puede utilizar el atributo poster de la etiqueta video. Por ello en este artículo te voy a enseñar como crearla automáticamente usando #ffmpeg

Publico nuevo artículo: «Crear miniaturas de imágenes en Django».
Si trabajas con #django puedes optimizar automáticamente todas las imágenes subidas. O, en otras palabras, crear una copia de menor tamaño de una imagen añadida a campo de un modelo. Y no solo eso, sino que también puedes convertir la imagen a un formato más moderno, como AVIF, limpiar los las imágenes no usadas, y mucho más.

And here is a good study comparing both lossy and lossless JPEG XL, AVIF, WEBP and JPEG.
Summary: in lossless compression, JPEG XL is much better than the others in all aspects. In lossy compression, AVIF wins in the image size department (not encode speed though) for medium to low quality images. JPEG XL wins in all dimensions in the medium to high quality scenario.
Additionally, nobody beats JPEG XL in terms of decoding speed.
Is it me or #AVIF support in #Firefox 130 on #Debian #Sid is just broken? (black pictures)
Edit: already fixed:
