//! # vacc-vaapi-encode
//!
//! VAAPI H.264 encode implementation using cros-libva.
//! Implements `vacc_core::Encoder` for `VideoCodec::EncodeH264`.
//!
//! Uses the driver's internal motion estimation (no per-macroblock buffer):
//! the app supplies packed SPS/PPS/slice headers, picture and slice
//! parameters, and NV12 input surfaces.
