Compare to lottie¶

The lottie (https://pypi.org/project/lottie/) python package is also capable of working with lottie files and telegram animated stickers (tgs). It is also able to support many input/output formats and vector graphics, without any dependency on extenral libraries such as librlottie. However some images it creates is broken (Example1 Example2). It seems librlottie is more stable in terms of rendering frames.

Compare to pyrlottie¶

The pyrlottie (https://pypi.org/project/pyrlottie/) python package is also able to convert lottie and tgs files to webp/gif. However, it works by calling executables gif2webp and lottie2gif with subprocess, and it does not support macOS.
