How o get current epg and video size

[dashne]

Hi every one
I tried to get current channel but it return nothing,also vdeo size is the same thing , my code as below:
for epg:

TEPGInfo ep;
ep.dwSize = sizeof(TEPGInfo);
SendMessage(m_hWndDream,WM_MODULE_MSG,DDMODAPI_GET_EPG_CURRENT,(LPARAM) &ep);
MessageBox(NULL,ep.EventName,ep.EventName,MB_OK);[/color]

and for getting video size:

DWORD tmp[6];
SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_GET_VIDEO_INFO, (LPARAM)tmp);
if(tmp[1])
{
st.Format(_T("%dx%d MPEG2"),tmp[1]&0xFFFF,tmp[1]>>16);
draw(st,400,15,RGB(0,255,0));
}

can anyone correct the code?

thanks

you EPG code seems to be ok.

here is the code to get video resolution
TVideoInfo vi;
vi.dwSize = sizeof(TVideoInfo);
SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_GET_VIDEO_INFO, (LPARAM)&vi);

vi.Width
vi.Height

thank you
in both case (EPG and video resolution):when I try to text out them into the osd screen ,it prints 0 x 0 for video resolution and - or nothing in some cases when Itry to text out the EPG.EventName and my code is:

void draw(CString str,int x,int y,COLORREF clr)
{

dcSurface.SetTextColor(clr);
dcSurface.TextOutA(x,y,str);
}
void UpdateOSD(TChannelInfo *pch)
{
oldbm = dcSurface.SelectBitmap(bmSurface);

dcSurface.FillSolidRect(rcSurface,RGB(200,0,0));
{

bdc.CreateCompatibleDC(dcSurface);
HBITMAP pOldBmp = bdc.SelectBitmap(HF);
dcSurface.BitBlt(0,0,1004,268,bdc,0,0,SRCCOPY); // Change pos/size as needed...
bdc.SelectBitmap(pOldBmp);
CString st;
st.Format(_T("%s"),pch->ChName);
draw(st,20,15,RGB(0,0,0));
st.Format(_T("%s"),pch->Provider);
draw(st,20,75,RGB(255,0,0));
st.Format(_T("%d"),pch->wVideo);
draw(st,20,135,RGB(0,255,0));
if(pch->ChType==1)
st.Format(_T("Channel Type : %s"),_T("TV"));
else if(pch->ChType==2)
st.Format(_T("Channel Type : %s"),_T("RADIO"));
else if(pch->ChType==3)
st.Format(_T("Channel Type : %s"),_T("DATA"));
else st.Format(_T("Channel Type : %s"),_T("wrong"));
draw(st,20,195,RGB(0,0,255));
TVideoInfo vi;
vi.dwSize = sizeof(TVideoInfo);
SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_GET_VIDEO_INFO, (LPARAM)&vi);
char buf[64];
wsprintf(buf,"%i x %i MPEG2",vi.Width,vi.Height);
MessageBox(NULL,buf,"ok",MB_OK); //====shows just 0 x 0 MPEG2
dcSurface.TextOutA(400,15,buf); //====shows just 0 x 0 MPEG2
TEPGInfo ep;
ep.dwSize = sizeof(TEPGInfo);
SendMessage(m_hWndDream,WM_MODULE_MSG,DDMODAPI_GET_EPG_CURRENT,(LPARAM) &ep);
MessageBox(NULL,ep.EventName,ep.EventName,MB_OK); //======shows nothing

}
dcSurface.SelectBitmap(oldbm); // Important -> de-select bitmap before calling DD API
//SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_OSD_REPAINT_SURFACE, surface_id);
SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_OSD_SHOW_SURFACE, surface_id);
SendMessage(m_hWndDream, WM_MODULE_MSG, DDMODAPI_OSD_REPAINT_SURFACE, surface_id);

}
and Iam putting function UpdateOSD(TChannelInfo *pch) in function AfterChannelChange Section ,every thing goes ok except the epg and video resolution .
can you fix that and sorry for annoying you


thanks

Where are the DD 's Programmer? Why there in no answer to my question? Is my question so difficult or impossible?
I do not think that, please please someone reply me




thanks

you should try and figure out most of it yourself.
I can only tell you what API function to use and what are its parameterrs

DD doesnt provide video res for H.264 channels otherwise it should work fine

[dashne]

But I tried every thing, every where I wrote the code it returns me nothing, just tell me where should I put the code (for example your code of getting the video resolution) to obtain the information





thanks

there is source code which can answer your questions
