Must be MFX_EXTBUFF_VIDEO_SIGNAL_INFO

 

 

VideoFormat

VideoFullRange

ColourPrimaries

TransferCharacteristics

MatrixCoefficients

ColourDescriptionPresent

These parameters define the video signal information.

For H.264, see Annex E of the ISO*/IEC* 14496-10 specification for the definition of these parameters.

For MPEG-2, see section 6.3.6 of the ITU* H.262 specification for the definition of these parameters. The field VideoFullRange is ignored.

For VC-1, see section 6.1.14.5 of the SMPTE* 421M specification. The fields VideoFormat and VideoFullRange are ignored.

If ColourDescriptionPresent is zero, the color description information (including ColourPrimaries, TransferCharacteristics, and MatrixCoefficients) will/does not present in the bitstream.
