float[] getMatrix(long presentationTimeUs,
                  boolean useHdr)
```
    Deprecated.
    
    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 toGlShaderProgram(Context, boolean).
    
    Returns:
    
    The RgbMatrix to apply to the frame.
  - toGlShaderProgram
```
default SingleFrameGlShaderProgram toGlShaderProgram(Context context,
                                                     boolean useHdr)
                                              throws VideoFrameProcessingException
```
    Deprecated.
    
    Description copied from interface: GlEffect
    
    Returns a GlShaderProgram that applies the effect.
    
    Specified by:
    
    toGlShaderProgram in interface GlEffect
    
    Parameters:
    
    context - A Context.
    
    useHdr - Whether input textures come from an HDR source. If true, colors will be in linear RGB BT.2020. If false, colors will be in linear RGB BT.709.
    
    Throws:
    
    VideoFrameProcessingException - If an error occurs while creating the GlShaderProgram.
