我们今天介绍一下EasyPlayerPro-win版的D3D画面旋转实现方法，可以从 https://github.com/tsingsee/EasyPlayerPro-Win 下载到工程代码。

其中定义的tagEASY_PARAM_ID枚举和EasyPlayerPro_Setparam(Easy_PlayerPro_Handle player, EASY_PARAM_ID param_id, EASY_HANDLE param)函数可以完成很多功能。

枚举类型中 EASY_PARAM_VDEV_D3D_ROTATE 为D3D画面旋转需要用到的类型，在HandleCommand函数中，如下方法实现旋转（每次旋转90度）：

  

   

    

     

    
    

     

      case POP_MENU_STREAM_D3D_ROTATE: 
      //d3d视频旋转
     
    
   

    

     

    
    

     

      	{
     
    
   

    

     

    
    

     
		
      int angle = 
      0;
     
    
   

    

     

    
    

     

      		EasyPlayerPro_Getparam(m_pMainDlg->m_hPlayer, EASY_PARAM_VDEV_D3D_ROTATE, &angle);
     
    
   

    

     

    
    

     

      		angle += 
      90; angle %= 
      360;
     
    
   

    

     

    
    

     

      		EasyPlayerPro_Setparam(m_pMainDlg->m_hPlayer, EASY_PARAM_VDEV_D3D_ROTATE, &angle);
     
    
   

    

     

    
    

     

      	}
     
    
   

    

     

    
    

     
	
      break;
