Weird pink stripe to the right side of AVIF generated from PNG #70

Closed pdobrescu closed 1 year ago

hello and thanks for this great converter!

I'm having some weird issues with certain PNG files that get a pink line to the right side, but only on some specific (old) mobiles. I tested on 2 Huawei devices, using Chrome (I don't have the exact version at hand right now) and the images look like this:

The source PNG is this one:

And the resulting AVIF is this one (it looks like I can't upload AVIFs to GH):

Test_AVIF.avif.zip

Do you have any ideas why that pink line shows up? Any help will be much appreciated!

The image you've attached displays fine for me in Firefox, Safari, and Chrome.

This looks like a problem reported previously, about a bug in Microsoft's AVIF decoder in Windows: #60

hello @kornelski and thanks for the quick reply. While I can understand this issue is similar to the one you mentioned, I have encountered it on 2 different Android devices. Is it possible that these older Android phones are using Microsoft's AVIF decoder? On newer Android devices the issue cannot be replicated indeed.

I've made a new release with latest rav1e encoder, which may or may not help.

I still suspect that it's the same bug in the decoders, and possibly Windows and old Android used the same library.
