BT878开发包

one BT878 capture 4 inputs
max. 4 BT878 capture 16 inputs in one system.
(if you have 4 BT878 in one card, make sure there is NO any external mux. if there is external mux pls provide the external mux/switch structure and we can implement it.)

as a simple demo, RGB555 is used in demo project for StretchDIBits;
it is better to use YUV422 format if you are a professional developer.
if you use memcpy you should know very well your display buffer and video renderer.

use DirectX is a better way.

1. Set BT878 sdk to output yuv422 data;
2. create surface with this format:
DDPIXELFORMAT ddpfBackSurfaceFormat = {
sizeof(DDPIXELFORMAT), DDPF_FOURCC,MAKEFOURCC('Y','U','Y','2'),0,0,0,0,0};
3. copy the yuv422 data on this surface;
4. Blt to screen surface.

用Blt方式可以实现放大缩小

one thing to note:
if(mysd.dwWidth*nBytePerPixel == (DWORD)mysd.lPitch)
{
// you can do block copy or just pass this surface buffer into BT878 SDK to get YUV422 data
}
else
{
// you have to copy line by line
}
