Bug fixes

• Fixed incorrect MMR coefficients (#197).
  • Users of the mmr_coef{_int} array are the only ones affected by this bug.
• Fixed error with --drop-hdr10plus for particular edge cases.

Features

• Refactored the RPU mapping structure. The changes also affect the exported serialized JSON.

  • This changes the structure of rpu_data_mapping. The NLQ parameters are also moved into it.

• Extended info --summary output:

  • RPU mastering display: The mastering display recorded in the RPU, from source_{min, max}_pq.
  • RPU content light level (L1): The MaxCLL and MaxFALL values calculated from L1.
  • L6 metadata: The L6 metadata present in the RPU.
  • L2 trims: The target display max brightness for which the RPU has L2 trim controls.

• Changed mode 2 behaviour to automatically enable remove_mapping for profile 7 FEL only.

  • This improves the default behaviour so that the output image is correct on playback.
  • For the old behaviour, mode 5 was added.

• Added plot subcommand, to plot the L1 metadata into a graph. It also shows the same info as info --summary.

• Improved memory usage, performance. RPU operations should be noticeably faster, ~50% speed up.

Notes:

• Linux release built on 893d6835ac109269b086acc254258a8436de67d5.
