lucascs@protonmail.com Lucas C.S. dkaraush/tlottie https://github.com/dkaraush/tlottie/issues tlottie renders Lottie animations -- the JSON vector-animation format Telegram uses for animated stickers and emoji -- and is written in Rust with no runtime dependencies. It dispatches at run time to hand-written SIMD backends: ARM NEON, x86_64 SSE2/AVX2/AVX-512 and WASM. Telegram Desktop replaced its bundled copy of media-libs/rlottie with this library in the 7.2 series and, on Linux, requires it as a system library rather than a bundled one. The package therefore installs only a static archive and the C API header, which is the shape tdesktop's cmake/external/tlottie module looks for.
