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:
"rgb"Matrix coefficients used by sRGB.
"bt709"Matrix coefficients used by BT.709.
"bt470bg"Matrix coefficients used by BT.601 PAL.
"smpte170m"Matrix coefficients used by BT.601 NTSC.
"bt2020-ncl"Matrix coefficients used by BT.2020 NCL.
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);
