about

nx_vcodec_realframe_gate.nx -- MEASURES our sovereign video codec on REAL video content, not a synthetic frame. The luma plane of ref_frame0.yuv is a real H.264 I-frame our own decoder (nx_h264_decode_frame) reconstructed 100% bit-exact vs ffmpeg (768x768 YUV420 -> first 589824 bytes = the Y plane). We encode that real frame as a keyframe at three quality points, prove an INDEPENDENT decoder reconstructs bit-exact, and report bytes + ratio + PSNR (centi-dB, via the shared qm_psnr_cdb). This closes RT-003's "synthetic frames" gap with zero third-party code.
