S5PV210 WINCE HDMI全屏显示的问题

2013-03-21

通过SMDK210自带的DOC《SMDKV210_WinCE60_TVOUT_UserManual.pdf》了解到

其HDMI驱动通过应用程序DeviceIoControl调用
操作顺序是：
1.打开TV
2.打开图像层（GRP层）
3.打开视频层（Video层）

以下这张图很好的说明了层的关系

给了我很大启示，网上很多人是在研究直接把fb放到GRP层，可是这样不能全屏的问题
发现Video层可以轻易解决大小的问题，但是现在卡在Video层需要YUV格式
而fb读出来的是RGB格式

DOC中
// because video processor supports only YUV420 NV12 type, need 2 values about address 
unsigned int uiTopYAddress;  // Y data start address of source image 
unsigned int uiTopCAddress;  // C data start address of source image 

所以，我在研究怎么解决这个格式转换问题，有大神说用VP——VIDEO PROCESSOR
不知道是什么东西，估计只能明天再话精力了解了。

今天code出来的：

我勒个去，被某大神坑了...看手册明白VP和MIXER的作用了...

原来安卓那边他们是，先用屏幕录像机，把RGB转成YUV再通过VP调整大小放到Video层，搞什么...为什么一开始不说清楚呢？！走弯路浪费公司人力资源而已嘛...
