[BHM-Bob]

Describe the bug

To Reproduce

Expected behavior
正常解码

Screenshots
None

Additional context
Apple和Xiaomi似乎将一个图片以512x512大小分块储存在heif中，但我需要直接解码一个更大尺寸的heif，这是依赖包的问题还是这个软件的问题呢？

On my device decoding large HEIF works fine, so maybe there's something special with your images or device.

Could you please provide some samples of HEIF and AVIF that fail for you?

There are several possible issues with this particular AVIF sample:

1. related to size: in Aves large images are tiled to prevent using all the memory. That is, only regions of the images are decoded, instead of the whole picture. But decoding regions is not supported by all decoders. It depends on whatever is shipped with the devices. On my device (and maybe yours too), decoding regions of AVIF is unsupported. I need to find a way to gracefully detect and disable tiling on devices with decoders that don't support it.

2. unrelated to size: even when I disable tiling, my device fails to decode your sample, even though it can decode other AVIF. Maybe it uses some advance features that are not supported by the codec bundled with Android.

Could you please provide a sample HEIF too?

By the way, some special HDR HEIF created by some Sony cameras fail to load on Android. Maybe that's your case?

The AVIF you provided can't be decoded with Google Photos or Samsung Gallery either, so I suppose it's just a codec limitation.

I'll take a look at your HEIF samples if you have some.

same content but in heif. I actually generate these two image from a jpeg using a python package. and it is ok to decode on windows if install HEVC coder.

I see. Then it's just these images that are incompatible with the standard Android codecs. Nothing i can do here.

Okay, thank you for your reply and your works.
