Comment (by Mingye Wang):

 About
 [https://github.com/search?q=repo%3AFFmpeg%2FFFmpeg+luminance&type=code
 other occurrences of "luminance"]:

 * JPEG is wrong, but it's grandfathered. Same for VBN.
 * The HDR stuff (`luminance_max` and `_min`) get it right, because a
 physical quantity is really involved.
 * postprocess `minLumQuality` doc should be changed.
 * VFs `histeq`, `bbox`, `lut`, `waveform`, `pp`, doc needs to be changed.
