about

nx_video_codec_v1_adapter.nx -- wraps NishiVideo v1 behind nx_codec. NishiVideo v1's native API: i64 pixel arrays + explicit (width_blocks, height_blocks) + writes total length to out-param. nx_codec's vtable: *u8 byte buffers + returns bytes-written, no dimension args. The adapter bridges by: - Storing width/height in adapter state (fixed at construction) - Treating *u8 src as packed luma bytes (1 byte/pixel, 0..255) - Unpacking to i64 for the codec - Repacking decoded i64 pixels back to *u8 luma on decode Per [[feedback-bits-up-exceed-never-match]]: zero new codec logic. All 11 WIN axes (per codec_grade_card.nx) belong to nx_video_codec.
