Hi, Now libheif use libde265 as heic decoder, but i want to use android's libhevc as heic decoder in libheif Is there any advise?

You can write a decoder plugin that uses libhevc. You can start from a copy of heif_decoder_libde265.cc. It should not be very difficult.

If you have something working, please contribute the code back to libheif as a merge request.

Hi, Have you completed this part of the work? I'm doing the same thing now, but the fetched hevc data passed to libhevc fails to decode.

And I write the hevc data which libheif extracted from .heic file to local file. Both libde265 and libhevc can't decode it. Using nokia/heif extract hevc data from .heic can be decoded success. The difference between nokia/heif's hevc data and libheif's hevc data just have 16 bytes differ.
