TI中文支持网对于DM8168 dvrrdk3.0的显示问题有几个疑问：
1、rdk中的display id代表的具体物理端口。VDIS_DEV_HDMI、VDIS_DEV_HDCOMP、VDIS_DEV_DVO2、VDIS_DEV_SD、VDIS_SYSFS_HDMI、VDIS_SYSFS_DVO2、VDIS_SYSFS_SD、VDIS_SYSFS_HDCOMP。
2、官方evm板的9022口输出，是否支持rgb或者yuv444输出？ 直接用dvrrdk3.0 demo中的Vdec_Vdis这个demo跑的，图像偏绿，在Vdis_params_init函数中修改语句为pContext->deviceParams[VDIS_DEV_HDCOMP].outputInfo.dataFormat = SYSTEM_DF_RGB24_888;， 显示还是不正确，请问下是什么方面的原因？

Note that the maximum supported line width is 1920 pixels. Furthermore, width and height values must always be an even number.• Support Simultaneous HD and SD output.• 2 video clocks to support two independent HD displays, the clock of third HD display will be tied to oneof the other two.
