rlottie-python's Issues

Help in building ARM 64-bit architecture (AARCH64) for rlottie.

i got this error when i installed a test apk in my phone, OSError: dlopen failed: "/data/data/org.lottie.lottie/files/app/_python_bundle/site-packages/rlottie_python/librlottie.so" is for EM_X86_64 (62) instead of EM_AARCH64 (183). How can i build a AARCH64 architecture to get this to work, or do you have a librlottie.so file that already has this architecture. I'm trying to build a simple lottie viewer to get this to work in the kivy framework, and it does work in my windows enviroment, but in andriod it doesn't work. Can you point me to right direction how i can accomplish this. anything in the c-language is beyond me. Any help is greatly apprecitated.

Bad GIF quality

Hi, the converted GIF has very strong color banding.

It looks even uglier when it moves.

Performance question/ discussion/ thoughts?

Hi, thank you very much for creating this library. Having something more portable than pyrlottie is awesome, as that's something I was kind of struggling with.

I've noticed that while there's a massive win in terms of cross-platform use, it seems to come at a slight performance cost of about 5%.

Giving myself a refresher on what pyrlottie does versus how I'm using rlottie-python:

I'm using asyncio.create_subprocess_shell with asyncio.Semaphore(multiprocessing.cpu_count()) to call the binaries directly.

With rlottie-python, I'm using concurrent.futures.ProcessPoolExecutor(max_workers=threads) as the executor.

To be honest, I'm not sure if this is a Windows issue. I'm curious if you've noticed any difference in performance between the libraries?

I think if we are in a place where performance is almost equal, then I'd like to start pointing people to this library and offer any dev support, rather than both of us maintaining two libraries that do the same thing.

I realize this is a bit of a brain dump, but I'd be really keen on hearing your thoughts. :)

Thank you

Is the code support to parse assets in json file?

i can get empty png files from my owner data when run rlottie-python/example/example.py

but i got right result in sample.json. The different between them is that i use raster image in assets.

Add wheels for the aarch64 architecture

Would it be possible to provide aarch64 (64-bit ARM) wheels for this project? At least the underlying library, rlottie, claims to support this architecture.

License

Hi, this package looks great. But I saw that it uses the GPL license and I think that will prevent me from being able to use it.

I’m hoping to use it to add support for Lottie files to an MIT-licensed package. I don’t think this is allowed under GPL. We’d have to change our license to GPL which means all our users would have to change their licenses as well.

Any chance you’ve considered a less viral license like LGPL which would require any changes to this library to be open source under LGPL but wouldn’t require users of the library to be GPL? (Or alternatively MIT or Apache-2.0 licenses which are even less restrictive.)
