Module parallel_tile_encoder 

Parallel AV1 tile encoding over raw frame bytes.

This module provides a low-level, frame-buffer-oriented API for splitting a YUV420p luma plane into tile regions and encoding them in parallel using rayon. It is the structural companion to super::parallel_tile_decoder on the encode side.

For a higher-level API that works with crate::frame::VideoFrame objects see super::tile_encoder::ParallelTileEncoder.

Structural implementation note

A full AV1 tile encode requires mode decision, transform coding, quantisation, and entropy coding — all tightly coupled to codec state. This module provides the structural scaffolding: correct tile splitting, parallel dispatch via rayon, and a minimal binary encoding (tile header + QP-XOR pixel data) suitable as a drop-in stand-in for the real pipeline.

Example

use oximedia_codec::av1::{RawTileEncoderConfig, encode_tiles_parallel};

let config = RawTileEncoderConfig {
    tile_cols: 2,
    tile_rows: 2,
    threads: 0,
    base_qp: 32,
};
let frame = vec![128u8; 1920 * 1080]; // synthetic luma
let tiles = encode_tiles_parallel(&frame, 1920, 1080, &config).expect("encode");
assert_eq!(tiles.len(), 4);
