License questions regarding pillow-heif

[joennlae]

First of all, really cool software 💯

While doing a license check, I noticed that the pillow-heif dependency is actually GPLv2 with the binary wheels.

Source: bigcat88/pillow_heif#111

I think we should use pi-heif: https://pypi.org/project/pi-heif/ but IANAL :-)

Just thought it would make sense to communicate that while I stumbled upon it.

@joennlae - Thanks for reporting this! pillow_heif looks like it has a BSD license, which is one of the license we accept for dependencies. The bindings to GPL licensed system dependencies are good to go from our stand point.

For us it looks like the code has a BSD license but the Wheel has a GPLV2. How do you reconsile this?

We came across the same issue and would have to patch unstructured as the binary wheels for pillow-heif is GPLv2 licensed. The author of pillow-heif is releasing pi-heif with the info:

This is a light version of Pillow-Heif with more permissive license for binary wheels. [...] All codebase are the same, refer to pillow-heif docs.

So please reconsider changing the dependency as it should be a drop in replacement and resolve GPL compatibility issues.

Thanks for the clarification. We're working on replacing pillow-heif with pi-heif.

We're now using py-heif. That changed was released in 0.15.8. Thanks all!
