请教下rt-media的切换彩色/黑白模式

[cruise33]

通过调用 AWVideoInput_SetIrParam 函数来切换黑白模式是正常的，但是再切回彩色模式，却不起作用，yuv仍然是黑白的，请问是哪里的问题呢？我看demo_video_in.c也是这么用的

	/* 切换 彩色/黑白 模式 */
	static RTIrParam pIrParam = {0};
	if(res.faces->isLive == 0){
		if(pIrParam.grey == 0){
			printf("set IR\n");
			pIrParam.grey = 1;
			pIrParam.ir_on = 1;
			pIrParam.ir_flash_on = 1;
			int ret = AWVideoInput_SetIrParam(config->channelId, &pIrParam);
			if(ret < 0)
				printf("set IR error\n");
		}
	}else{
		if(pIrParam.grey == 1 && frame_cnt == 50){
			printf("set RGB\n");
			pIrParam.grey = 0;
			pIrParam.ir_on = 0;
			pIrParam.ir_flash_on = 0;
			int ret = AWVideoInput_SetIrParam(config->channelId, &pIrParam);
			if(ret < 0)
				printf("set RGB error\n");
		}
	}

这样就可以了

int ISP_RGB_GREY(int chnID, int Grey)
{
	RTIspCtrlAttr isp_ctrl_attr;
	if(Grey == 0){
		isp_ctrl_attr.isp_attr_cfg.cfg_id = RT_ISP_CTRL_IR_STATUS;
		isp_ctrl_attr.isp_attr_cfg.ir_status = 0;
	}
	else{
		isp_ctrl_attr.isp_attr_cfg.cfg_id = RT_ISP_CTRL_IR_STATUS;
		isp_ctrl_attr.isp_attr_cfg.ir_status = 1;
	}
	AWVideoInput_SetIspAttrCfg(chnID, &isp_ctrl_attr);
	usleep(500*1000);
	return 0;
}
