Conversion from YUV444 to RGB888

Answer 1

Well i got the Solution for this

//------------------------------------------------------------------------------
//
// Function: PP_CSC_YUV444_RGB888Test
//
// This function tests the Post-processor
// 
// 
//
// Parameters:
//      uiMsg
//           [in] Ignored.
//
//      tpParam
//           [in] Ignored.
//
//      lpFTE
//           [in] Ignored.
//
// Returns:
//      Specifies if the test passed (TPR_PASS), failed (TPR_FAIL), or was
//      skipped (TPR_SKIP).
//
