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

Detlef,

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

best,
Chao

Very useful! I'm confusing

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