FFmpeg exposes iOS VideoToolbox and Android MediaCodec so hardware H.264 decoding returns platform-specific frames instead of raw YUV buffers, enabling a zero-copy rendering pipeline into CVPixelBuffer-backed textures. The repo contains a VideoToolbox device context that hands back CVPixelBuffer frames and a MediaCodec path that can attach an Android Surface and produce a media codec pixel format. iOS path is mature and synchronous; Android path is more complex and still evolving but functional for decoding and rendering.
