![]() ![]() If you got the HEIC container/file correct, I don't see why macOS 10.14 wouldn't support 3rd party dynamic wallpapers. I'm guessing this XMP will be helpful to anyone trying to reverse engineer the format, so that people can make their own dynamic wallpapers. heic file actually contained 977 different parts: 16 images, each made up of 60 individual tiles and 1 grid reference, plus one XMP metadata file. Running this command: mp4box -info mojave_dynamic.heic revealed the. ![]() I then found MP4box (part of GPAC) which I also couldn't get to export the images-but it provided loads of helpful information. Next I checked out MagickStudio which has HEIF support, but proved to be a dead end when trying to work with multi-image HEIFs. While I could get it to display the first image stored in the file, getting it to display any of the other images proved unfruitful. I was having trouble compiling their tools, but I noticed they also provided a Javascript version of their HEIF reader (used on the example page to load the images.) I took that (actually just took the whole example page) and reverse engineered it to display the mojave_dynamic.heic file. However, the HEIF file spec allows for multiple images to be stored in one file (as is the case with this dynamic wallpaper) but is widely unsupported. So the HEIF image format is fairly well supported, especially on Mac with Quick Look, Preview, Photoshop all being able to open HEIF files. ![]()
