我們今天介紹一下EasyPlayerPro-win版的D3D畫面旋轉實現方法，可以從 https://github.com/tsingsee/EasyPlayerPro-Win 下載到工程代碼。

其中定義的tagEASY_PARAM_ID枚舉和EasyPlayerPro_Setparam(Easy_PlayerPro_Handle player, EASY_PARAM_ID param_id, EASY_HANDLE param)函數可以完成很多功能。

typedef enum tagEASY_PARAM_ID
{
	//++ public
	// duration & position
	EASY_PARAM_MEDIA_DURATION = 0x1000,
	EASY_PARAM_MEDIA_POSITION,

	// media detail info
	EASY_PARAM_MEDIA_INFO,
	EASY_PARAM_VIDEO_WIDTH,
	EASY_PARAM_VIDEO_HEIGHT,

	// video display mode
	EASY_PARAM_VIDEO_MODE,

	// audio volume control
	EASY_PARAM_AUDIO_VOLUME,

	// playback speed control
	EASY_PARAM_PLAY_SPEED,
	EASY_PARAM_PLAY_SPEED_TYPE,

	// video decode thread count
	EASY_PARAM_DECODE_THREAD_COUNT,

	// visual effect mode
	EASY_PARAM_VISUAL_EFFECT,

	// audio/video sync diff
	EASY_PARAM_AVSYNC_TIME_DIFF,

	// player event/audio/video callback
	EASY_PARAM_PLAYER_CALLBACK,
	// player event/audio/video callback userdata
	EASY_PARAM_PLAYER_USERDATA,

	// audio/video stream
	EASY_PARAM_AUDIO_STREAM_TOTAL,
	EASY_PARAM_VIDEO_STREAM_TOTAL,
	EASY_PARAM_SUBTITLE_STREAM_TOTAL,
	EASY_PARAM_AUDIO_STREAM_CUR,
	EASY_PARAM_VIDEO_STREAM_CUR,
	EASY_PARAM_SUBTITLE_STREAM_CUR,

	//++ for media record 
	EASY_PARAM_RECORD_TIME,
	EASY_PARAM_RECORD_PIECE_ID,
	//-- for media record
	//-- public

	//++ for audio render type
	EASY_PARAM_ADEV_RENDER_TYPE = 0x2000,
	EASY_PARAM_ADEV_GET_CONTEXT,
	EASY_PARAM_ADEV_MUTE,
	//-- for audio render type

	//++ for vdev
	EASY_PARAM_VDEV_RENDER_TYPE = 0x3000,
	EASY_PARAM_VDEV_FRAME_RATE,
	EASY_PARAM_VDEV_GET_CONTEXT,
	EASY_PARAM_VDEV_POST_SURFACE,
	EASY_PARAM_VDEV_GET_D3DDEV,
	EASY_PARAM_VDEV_D3D_ROTATE,
	EASY_PARAM_VDEV_RENDER_SHOW,
	//-- for vdev

	//++ for render
	EASY_PARAM_RENDER_UPDATE = 0x4000,
	EASY_PARAM_RENDER_START_PTS,
	//-- for render

}EASY_PARAM_ID;

枚舉類型中 EASY_PARAM_VDEV_D3D_ROTATE 為D3D畫面旋轉需要用到的類型，在HandleCommand函數中，如下方法實現旋轉（每次旋轉90度）：

case POP_MENU_STREAM_D3D_ROTATE: //d3d視頻旋轉
	{
		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;
