The license in the provided implementation seems to be a custom, non-commercial, non-OSI-approved license [1]. It also includes a patent grant, but excludes codec patents, making it even more useless (Nokia can't license other people's HEVC patents, of course). It's based on the LGPL-licensed libde265 library.

Lol Nokia has Codec patents on HEVC too. So they're granting a license that doesn't include their HEVC patents or anyone elses? Is this the library equivalent of a Honeypot? Maybe they're not getting enough royalties.

License notwithstanding, has anyone tried to create a HEIF file? There are a few samples on this site, but even given the code they've provided on GitHub I can't seem to create a HEIF image from another image format. Their code seems to take an H265 HEVC bytestream as input, which is fine, but I can't find anything that will build an HEVC bytestream for an image rather than a video...

You can easily turn an image into a video, or into HEVC, with ffmpeg.

Haha thanks - I didn't think it supported H265 but it looks like I just have to build it from source (https://trac.ffmpeg.org/wiki/Encode/H.265). Suppose that's still fairly "easily" ;-)

Update: I figured out how to do this and posted my findings here: http://jpgtoheif.com/
