Doesn't work? #1

Hello,

I ran the demo in Chrome Version 96.0.4664.55 and the resulting file does not open on Mac and does not seem to work when opened in Chrome. Has there been a breaking update to Chrome perhaps?

Hi George, thanks for the hint, unfortunately I can confirm that the code is broken in current chrome versions. I don't know yet what's going on, maybe chrome now adds some extra (metadata?) chunk to recorded WebPs that is incombatible with animated WebP? I will investigate... Valentin

ps: I suspect that those ICCP color profile chunks added to every frame could be the culprit..

But in case it helps, my APNG Recorder still works fine in Chrome: https://valentin.dasdeck.com/projects/apng_encoder/demo_cam_recorder.html https://github.com/59de44955ebd/APNG-Encoder

FYI, in the meantime I fixed the problem, see demo at: https://valentin.dasdeck.com/projects/awebp_encoder/demo.html (tested in Chrome 96.0.4664.45 Win-x64)

The incompatibility of the previous code was caused by Chrome now creating "Extended File Format" instead of previous "Simple File Format" WebP images when canvas.toBlob(...) is called.
