about

nx_vp8probe.nx -- DIAGNOSTIC bring-up harness for the C3 VP8 keyframe decoder. Decodes one lossy WebP file and prints machine-readable evidence: dimensions, global Y/U/V means, and an 8x8 grid of Y tile means that an INDEPENDENT oracle (libwebp via PIL, laptop-side) can be compared against number-by-number. Also embeds the prob-128 bool-decoder property check (prob-128 decode IS the raw bitstream) so a desync shows up here first. usage: nx_vp8probe <file.webp> license_tier: ORIGINAL
