initialization interfaces has been changed for threads count.
if you want to set concrete threads count by system, please specify thread count with it.
std threads:
tvg::Initializer::init(tvg::CanvasEngine::Sw, std:🧵:hardware_concurrency());
if your system provides designed threads info, you can use it.
efl:
tvg_engine_init(TVG_ENGINE_SW, eina_cpu_count());
I recommend to avoid max threads usage for better performance.
