Maybe helpful, UMC & Direct X

Hi @all,

i don't konw if anybody is interessted by this theme, but i had the problem to show the video output under 16, 24 and 32 bit grifik-cards under windows.

So i made some changes in the umc, maybe its helpfull for someone:

1) Extentumc_dx_overlay_formats in dx_drv.cpp to this:

constDDPIXELFORMATumc_dx_overlay_formats[]=
{
{sizeof(DDPIXELFORMAT),DDPF_FOURCC|DDPF_YUV,MAKEFOURCC('Y','V','1','2'),12,0,0,0,0},/*YV12*/
{sizeof(DDPIXELFORMAT),DDPF_FOURCC|DDPF_YUV,MAKEFOURCC('Y','U','Y','2'),16,0,0,0,0},/*YUY2*/
{sizeof(DDPIXELFORMAT),DDPF_FOURCC|DDPF_YUV,MAKEFOURCC('U','Y','V','Y'),16,0,0,0,0},/*UYVY*/
{sizeof(DDPIXELFORMAT),DDPF_FOURCC|DDPF_YUV,MAKEFOURCC('N','V','1','2'),12,0,0,0,0},/*NV12*/
    {sizeof(DDPIXELFORMAT),DDPF_RGB,0,16,0x00007C00,0x000003E0,0x0000001F,0},				/*RGB555*/
{sizeof(DDPIXELFORMAT),DDPF_RGB,0,16,0xf800,0x07e0,0x001f,0},/*RGB565*/
    {sizeof(DDPIXELFORMAT),DDPF_RGB,0,24,0x00FF0000,0x0000FF00,0x000000FF,0},/*RGB24*/
    {sizeof(DDPIXELFORMAT),DDPF_RGB,0,32,0x00FF0000,0x0000FF00,0x000000FF,0}/*RGB32*/
};
2) extend in dx_drv.h the DDVideoDrvColorFomat to this:
typedefenumDDVideoDrvColorFormat
{
DXVideoDrv_YV12=0,
DXVideoDrv_YUY2=1,
DXVideoDrv_UYVY=2,
DXVideoDrv_NV12=3,
    DXVideoDrv_RGB555=4,
DXVideoDrv_RGB565=5,
    DXVideoDrv_RGB24	=6,
    DXVideoDrv_RGB32	=7
 
}DDVideoDrvColorFormat;



3) add in blt_video_render.cpp (for example) in the Init function:
		caseRGB555:
			DrvParams.dd_fmt=DXVideoDrv_RGB555;
			break;
		caseRGB32:
			DrvParams.dd_fmt=DXVideoDrv_RGB32;
			break;
		caseRGB24:
			DrvParams.dd_fmt=DXVideoDrv_RGB24;
			break;
Now you can initialize UMC::AVSync also with RGB555, RGB24 & RGB32 

It works fine, best Regards

Detlef,

Thanks for sharing it. I think it is very useful for those who are using the render code.

best,

Very useful! I'm confusing with the DDPIXELFORMAT struct. Thanks for sharing it.
