GstVideo.VideoColorimetry

Fields

Name	Type	Access	Description
matrix	GstVideo.VideoColorMatrix	r/w	the color matrix. Used to convert between Y’PbPr and non-linear RGB (R’G’B’)
primaries	GstVideo.VideoColorPrimaries	r/w	color primaries. used to convert between R’G’B’ and CIE XYZ
range	GstVideo.VideoColorRange	r/w	the color range. This is the valid range for the samples. It is used to convert the samples to Y’PbPr values.
transfer	GstVideo.VideoTransferFunction	r/w	the transfer function. used to convert between R’G’B’ and RGB

Details

class GstVideo.VideoColorimetry

Structure describing the color info.

from_string(color)

Parameters:

color (str) – a colorimetry string

Returns:

True if color points to valid colorimetry info.

Return type:

bool

Parse the colorimetry string and update self with the parsed values.

is_equal(other)

Parameters:

other (GstVideo.VideoColorimetry) – another GstVideo.VideoColorimetry

Returns:

True if self and other are equal.

Return type:

bool

Compare the 2 colorimetry sets for equality

New in version 1.6.

is_equivalent(bitdepth, other, other_bitdepth)

Parameters:

• bitdepth (int) – bitdepth of a format associated with self

• other (GstVideo.VideoColorimetry) – another GstVideo.VideoColorimetry

• other_bitdepth (int) – bitdepth of a format associated with other

Returns:

True if self and other are equivalent.

Return type:

bool

Compare the 2 colorimetry sets for functionally equality

New in version 1.22.

matches(color)

Parameters:

color (str) – a colorimetry string

Returns:

True if color conveys the same colorimetry info as the color information in info.

Return type:

bool

Check if the colorimetry information in info matches that of the string color.

to_string()

Returns:

a string representation of self or None if all the entries of self are unknown values.

Return type:

str or None

Make a string representation of self.
