How leftcontroller0518/botamochi works

Botamochi is a C# video rendering and hardware-encoding engine. The principal workflow parses render options, generates animated frames, converts or packs them as NV12, streams them through a bounded encoder queue, and exports a video through FFmpeg. Documented GPU rendering/compute, SIMD conversion, direct multi-session NVENC, and hardware-encoder selection are also represented. Edges follow the sampled entry point and caller excerpts or README statements; unsampled feature internals are shown without inferred call chains.

Main entry points: Program.cs Render entry point · DirectRender.cs Direct render coordinator · FfmpegProcessBridge.cs FFmpeg bridge · ColorBarsNv12Renderer.cs Color bars renderer
