[BUG] MKV Advanced Video Signaling Options Have No Effect

[Selur]

My point is, that from what I see Hybrid does the flagging correctly or do you see a mistake in the mkvmerge command line and/or the resulting output?

Looking at https://mkvtoolnix.download/doc/mkvmerge.html:

Matrix:

--color-matrix-coefficients TID:n     

Sets the matrix coefficients of the video used to derive luma and chroma values from red, green and blue color primaries. The parameter n is an integer rangeing from 0 and 10.

Valid values and their meaning are:

0: GBR, 1: BT709, 2: unspecified, 3: reserved, 4: FCC, 5: BT470BG, 6: SMPTE 170M, 7: SMPTE 240M, 8: YCOCG, 9: BT2020 non-constant luminance, 10: BT2020 constant luminance

values.clear();
  values << QString("GBR");
  values << QString("BT709");
  values << QString("Unspecified");
  values << QString("Reserved");
  values << QString("FCC");
  values << QString("BT470BG");
  values << QString("SMPTE 170M");
  values << QString("SMPTE 240M");
  values << QString("YCGCO");
  values << QString("BT2020 Non-constant Luminance");
  values << QString("BT2020 Constant Luminance");
  this->addListField(QString("mkvColorMatrix"), values.at(0), values, false);

(from Hybrid source code)

Transfer:

--color-transfer-characteristics TID:n     

The transfer characteristics of the video.

Valid values and their meaning are:

0: reserved, 1: ITU-R BT.709, 2: unspecified, 3: reserved, 4: gamma 2.2 curve, 5: gamma 2.8 curve, 6: SMPTE 170M, 7: SMPTE 240M, 8: linear, 9: log, 10: log sqrt, 11: IEC 61966-2-4, 12: ITU-R BT.1361 extended color gamut, 13: IEC 61966-2-1, 14: ITU-R BT.2020 10 bit, 15: ITU-R BT.2020 12 bit, 16: SMPTE ST 2084, 17: SMPTE ST 428-1; 18: ARIB STD-B67 (HLG)

values.clear();
  values << QString("Reserved");
  values << QString("ITU-R BT.709");
  values << QString("Unspecified");
  values << QString("Reserved");
  values << QString("Gamma 2.2 curve");
  values << QString("Gamma 2.8 curve");
  values << QString("SMPTE 170M");
  values << QString("SMPTE 240M");
  values << QString("Linear");
  values << QString("Log");
  values << QString("Log Sqrt");
  values << QString("IEC 61966-2-4");
  values << QString("ITU-R BT.1361 Extended Colour Gamut");
  values << QString("IEC 61966-2-1");
  values << QString("ITU-R BT.2020 10 bit");
  values << QString("ITU-R BT.2020 12 bit");
  values << QString("SMPTE ST 2084");
  values << QString("SMPTE ST 428-1");
  values << QString("ARIB STD-B67 (HLG)");
  this->addListField(QString("mkvColorTransferCharacteristics"), values.at(0), values, false);

(from Hybrid source code)
Primaries:

--color-primaries TID:n     

Sets the color primaries of the video.

Valid values and their meaning are:

0: reserved, 1: ITU-R BT.709, 2: unspecified, 3: reserved, 4: ITU-R BT.470M, 5: ITU-R BT.470BG, 6: SMPTE 170M, 7: SMPTE 240M, 8: FILM, 9: ITU-R BT.2020, 10: SMPTE ST 428-1, 22: JEDEC P22 phosphors

values.clear();
  values << QString("Reserved");
  values << QString("ITU-R BT.709");
  values << QString("Unspecified");
  values << QString("Reserved");
  values << QString("ITU-R BT.470M");
  values << QString("ITU-R BT.470BG");
  values << QString("SMPTE 170M");
  values << QString("SMPTE 240M");
  values << QString("FILM");
  values << QString("ITU-R BT.2020");
  values << QString("SMPTE ST 428-1");
  values << QString("JEDEC P22 phosphors");
  this->addListField(QString("mkvColourPrimaries"), values.at(0), values, false);

The flagging seems to match what Hybrid offers.
