about

nx_jpeg_decode_image_test.nx -- KAT for the top-level image decoder. Minimal 8x8 grayscale: 1 component, 1 MCU, 1 block. Bitstream: DC category 0 + AC EOB = "0 0" packed MSB-first = 0x00. All coefficients zero -> IDCT all zeros -> level shift -> 128. Expected output plane: 8x8 of 128. expect_exit: 0 license_tier: ORIGINAL
