Encoder

[T8RIN]

Will the encoder be added?

[umjammer]

currently no.

imo

• java should read every data format
• java should write data using the best (≒ de facto standard) format only

i chose 'avif' as the de facto standard.
so writing 'jpeg-xl' has not been implemented yet.

do u still want this feature?
this is a hobby project, wait patiently for that time.

Is there is java lob which can write avif without cpp ?

[umjammer]

it seems there is no avif in pure java.

i tried to write avif in pure java before,
but i realized libavif is just an integration library for several codec libraries.

that means libavif consists of

• libaom (encoder and decoder)
• dav1d (decoder)
• libgav1 (decoder)
• rav1e (encoder)
• SVT-AV1 (encoder)

and most of those library are written in assembler not even in C!
porting those assemblers into java is beyond my capacity.
so i quit porting libavif into java.

recently macos and windows? supports avif os natively.
it's better to wait until android supports avif natively.

Sounds quite interesting :)

Didn't know that it was written on an assembler, that is mind-blowing for me, because i thought it was C...

jpeg-xl is better than avif???

anyway avif is still de facto standard because my chrome browser doesn't support jpeg-xl yet
