This avifDecoderNextImage seems used for AVIF animated image (really rare but supported).

I think this need more information to test and increase performance. May need libavif's upstream help :)

Known issue for animated AVIF. But we have no better way to avoid this.

A possible way is like using the internal API of AOM like https://github.com/SDWebImage/SDWebImageWebPCoder

Which calculate a latest reusable frame index and canvas without re-scan, but it's complicated and I have no free time to complete.

You can have a try by different AVIF codec (for decoding)

From v0.11.0, we support using SDImageCoderAVIFDecodeCodecChoice to chooce codec at runtime. You can install all 4 AVIF decoding codec and compare them one by one
