Class AvHuffCodec

Namespace

CHDSharp.Encoder

Assembly

CHDSharpLib.dll

MAME A/V Huffman codec ('avhu'), matching chd_avhuff_compressor: each hunk is one raw 'chav' A/V frame (assembled by EncodeLaserDisc(string, string, uint, IReadOnlyList<uint>?, ChdEncodeOptions?, long, long?, CancellationToken)) compressed as delta-RLE Huffman video + per-channel mono FLAC audio via CHDSharp.Encoder.AvHuffEncoder. Multi-frame hunks (hunkBytes > bytesPerFrame) are stored raw, matching MAME's codec-chain behavior where the avhuff compress fails on already-encoded data. Decodable by CHDSharpLib's ChdReaders.AvHuff and chdman.
