5.16.2.21 #define FE2_VP8_SHARPNESS
Codec parameter for sharpness.
Controls the sharpness of the image in the output. This setting does not impact any other setting and is
largely a matter of personal preference. A low sharpness setting will result in fewer visible artifacts but
may blur the image somewhat; a high sharpness will result in a sharper image but may result in more visible
artifacts.
