No grid items found

[lawik]

I've just compiled this and I'm trying the samples found at https://nokiatech.github.io/heif/examples.html and getting only the message "No grid items founds!" on all the ones I've tried. Any clue if I've messed something up?

This is expected behaviour at the moment ;). As we state in the Readme: "Converts HEIF images created on iOS 11 devices", tifig is currently focused exclusively on photos shot with an iPhone 7 or newer devices. Those HEIF images are based on HEVC encoded tiles layed out in a grid. To support the whole HEIF standard, quite some more work would be needed: Support for other encodings (AVC, JPG, TIFF), image collections, time based animations, derived images, media content and you name it.

However, what we will do is improve that error message.

Seems to work on the iOS ones I have, yes. This format seems a bit complex when two different still images are that different.

Good job at any rate, this will help us quite a bit.

Jup, the whole HEIF standard is pretty large and complex ;). However, we might implement single frame HEVC encoded HEIFs at some future point, shouldn't be too complex with what we already have.

The error message has been improved in the meanwhile, so I'm closing this ticket.
