      • getMatrix

        float[] getMatrix​(long presentationTimeUs,
                          boolean useHdr)
        Returns the 4x4 RGB transformation matrix to apply to the color values of each pixel in the frame with the given timestamp.
        Parameters:
        presentationTimeUs - The timestamp of the frame to apply the matrix on.
        useHdr - If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709. Must be consistent with useHdr in toGlTextureProcessor(Context, boolean).
        Returns:
        The RgbMatrix to apply to the frame.
