52 * If VA_FEI_FUNCTION_ENC_PAK is set, VA_FEI_FUNCTION_ENC and VA_FEI_FUNCTION_PAK
53 * will be ignored if set also. Combination of VA_FEI_FUNCTION_ENC and VA_FEI_FUNCTION_PAK

55 * If VA_FEI_FUNCTION_PAK is set, two extra input buffers for PAK are needed:
56 * VAEncFEIMVBufferType and VAEncFEIMBCodeBufferType.
57 * VA_FEI_FUNCTION_ENC_PAK is recommended for best performance.
