DM368 OSDWIN0的尺寸与实际的不一样，要怎样调整呢？

各位大神：

我在用DM368的VPBE调试一款屏的显示。我用的屏幕是240*320的竖屏。，然后窗口的分辨率设置成960*320时刚好占满整个屏幕。

然后VENC_DCLKCTL = 0x0003;   VENC_DCLKPTN0 = 0x0003; 这两句的设定貌似改变了VPBE取数据的方式，然后从系统导入一张RGB888的图片显示时，数据怎么排列都有问题，以下是我的寄存器设定，哪位大神帮忙看一下哪里出了问题。

VPSS_CLKCTL = 0x00000018; // Enable DAC and VENC clock, both at 27 MHz

你好，

请问你使用的RGB888在内存里面是如下格式么？下面的信息可以在DM36x VPBE guide里面找到。
