VideoColorSpace.matrix

The matrix read-only property of the VideoColorSpace interface returns the matrix coefficient of the video. Matrix coefficients describe the relationship between sample component values and color coordinates.

A string containing one of the following values:

"rbg"

Matrix coefficients used by sRBG.

"bt709"

Matrix coefficients used by BT.709.

"bt470bg"

Matrix coefficients used by BT.601 PAL.

"smpte170m"

Matrix coefficients used by BT.601 NTSC.

In the following example, colorSpace is a VideoColorSpace object returned from VideoFrame. The value of matrix is printed to the console.

let colorSpace = VideoFrame.colorSpace
console.log(colorSpace.matrix);
