vipsthumbnail not working for heic, how to debug?

[fuji246]

I've compiled libvips for arm64, and having problem using vipsthumbnail generating thumbnail for heic file, it should compiled with heif support, but not sure why it doesn't recognize heic file.

pi@raspberrypi:~/Downloads/libvips $ /usr/local/bin/vipsthumbnail /media/lomorage/bob/Photos/master/2018/03/30/20180330_4.heic
/usr/local/bin/vipsthumbnail: unable to thumbnail /media/lomorage/bob/Photos/master/2018/03/30/20180330_4.heic
VipsForeignLoad: "/media/lomorage/bob/Photos/master/2018/03/30/20180330_4.heic" is not a known file format

Hello @fuji246,

It's a two-step process: libheif needs to be compiled for HEIC support (it can also support AVIF), then libvips needs to be compiled for libheif support.

It looks like you have libvips built with libheif, so I'd guess your libheif is missing HEIC. I see:

$ pkg-config libheif --print-variables
builtin_avif_decoder
builtin_avif_encoder
builtin_h265_decoder
builtin_h265_encoder
exec_prefix
includedir
libdir
pcfiledir
prefix

[jcupitt]

I added a note about this to the README.

[fuji246]

Thank you for your quick response.

I've checked my build, seems it's the same with the output above

pi@raspberrypi:~/Downloads $ pkg-config libheif --print-variables
builtin_avif_decoder
builtin_avif_encoder
builtin_h265_decoder
builtin_h265_encoder
exec_prefix
includedir
libdir
pcfiledir
prefix

Huh curious. Could you share the file that's failing to load?

This one works for me:

I actually tried the same file on mac and it works.

I tried to gdb and set breakpoints below, but I'm not familiar those gobjects, not sure where is the code that dynamic build the map to load the heic class.

Breakpoint 4, vips_thumbnail_file_get_info (thumbnail=0x5555641ff0) at thumbnail.c:1023
