+ /**
+ * \brief VAEntrypointFEI
+ *
+ * The purpose of FEI (Flexible Encoding Infrastructure) is to allow applications to
+ * have more controls and trade off quality for speed with their own IPs.
+ * The application can optionally provide input to ENC for extra encode control
+ * and get the output from ENC. Application can chose to modify the ENC
+ * output/PAK input during encoding, but the performance impact is significant.
+ *
+ * On top of the existing buffers for normal encode, there will be
+ * one extra input buffer (VAEncMiscParameterFEIFrameControl) and
+ * three extra output buffers (VAEncFEIMVBufferType, VAEncFEIMBModeBufferType
+ * and VAEncFEIDistortionBufferType) for VAEntrypointFEI entry function.
+ * If separate PAK is set, two extra input buffers
+ * (VAEncFEIMVBufferType, VAEncFEIMBModeBufferType) are needed for PAK input.
