socket and direct show

[Dave]

Hi,

i am writing a c# application that use direct show to play mpg file but when
i declere a socket in my c# application i just cant play the file enymore,

It seems that the problem is because we are tring to write this lines:

IPAddress ipAddress = Dns.Resolve("lo calhost").Addre ssList[0];

TcpListener tcpServerListen er = new TcpListener(ipA ddress,5555);

And not the openning of thread!

When we just try to open or use win sock the file playin is hang like
someone blocking it!!!

The code that play the file is inside managed c++ class assembly the my c#
application link to it,

The c++ code for playing the file:

CoCreateInstanc e(CLSID_FilterG raph, NULL,
CLSCTX_INPROC_S ERVER,IID_IGrap hBuilder, (void **)&m_pGraph[m_nDevices]);

....

m_pGrabber[m_nDevices].CoCreateInstan ce( CLSID_SampleGra bber );

CComQIPtr< IBaseFilter, &IID_IBaseFilte r >
pGrabBase(m_pGr abber[m_nDevices]);

HRESULT hr = m_pGraph[m_nDevices]->AddFilter( pGrabBase, L"Grabber" );
//Force it to connect to video, 24 bit

CMediaType VideoType;

VideoType.SetTy pe( &MEDIATYPE_Vide o );

//VideoType.SetSu btype( &MEDIASUBTYPE_R GB24 );

VideoType.SetSu btype( &MEDIASUBTYPE_Y UY2 );

hr = m_pGrabber[m_nDevices]->SetMediaType ( &VideoType ); // shouldn't fail
hr = m_pGraph[m_nDevices]->QueryInterface (IID_IMediaSeek ing, (void
**)&m_pMediaSee king[m_nDevices]);

hr =m_pMediaSeekin g[m_nDevices]->SetTimeFormat( &TIME_FORMAT_FR AME);

// add the grabber to the graph

//hr = m_pGraph[m_nDevices]->AddFilter( pGrabBase, L"Grabber" );

hr = m_pGrabber[m_nDevices]->SetBufferSampl es( FALSE );

hr = m_pGrabber[m_nDevices]->SetOneShot( FALSE );

hr = m_pGrabber[m_nDevices]->SetCallback(&m CB[m_nDevices], 1 );

//LPCWSTR str1=(LPCWSTR)s tr;

hr = m_pGraph[m_nDevices]->RenderFile((LP CWSTR)lstr, NULL);

hr = m_pGraph[m_nDevices]->QueryInterface (IID_IMediaCont rol, (void
**)&m_pMediaCon trol[m_nDevices]);
LONGLONG lDuration,lPos, lPos1,llAmount= 0;

hr = m_pMediaSeeking[m_nDevices]->SetTimeFormat( &TIME_FORMAT_FR AME);

hr = m_pMediaSeeking[m_nDevices]->GetDuration(&l Duration);

hr = m_pMediaSeeking[m_nDevices]->GetCurrentPosi tion(&lPos);

hr = m_pMediaSeeking[m_nDevices]->GetStopPositio n(&lPos1);
IBasicVideo* pVideo;

hr = m_pGraph[m_nDevices]->QueryInterface (IID_IBasicVide o,(void **)&pVideo);

LONG lWidth, lHeight;

hr = pVideo->GetVideoSize(& lWidth,&lHeight );

REFTIME rtTime;

hr = pVideo->get_AvgTimePer Frame(&rtTime);

double dRate;

dRate = 1.0/rtTime;
llAmount=(LONGL ONG)(lPos1/dRate);
// ask for the connection media type so we know how big

// it is, so we can write out bitmaps

//

AM_MEDIA_TYPE mt;

ZeroMemory(&mt, sizeof(mt));

hr = m_pGrabber[m_nDevices]->GetConnectedMe diaType( &mt );

VIDEOINFOHEADER * vih = (VIDEOINFOHEADE R*) mt.pbFormat;

int h=(int)vih->bmiHeader.biHe ight;

int w=(int)vih->bmiHeader.biWi dth;

FreeMediaType( mt );
//mCB[m_nDevices].m_hWinHwd=g_hw nd;

// Specify the owner window.

m_pGraph[m_nDevices]->QueryInterface (IID_IVideoWind ow, (void
**)&m_pWindow[m_nDevices]);

m_pWindow[m_nDevices]->put_Owner((OAH WND)g_hwnd);

m_pWindow[m_nDevices]->put_WindowStyl e(WS_CHILD | WS_CLIPSIBLINGS );
RECT grc;

GetClientRect(g _hwnd, &grc);

//::ScreenToClien t(&grc);

m_pWindow[m_nDevices]->SetWindowPosit ion(grc.left, grc.top,
(grc.right-grc.left), (grc.bottom-grc.top));

// Run the graph.

m_pMediaControl[m_nDevices]->Run();

Everything work fine and playing whell until I write the line above to
define the socket, Why???

I am using the

class CSampleGrabberC B : public ISampleGrabberC B

{

....

}

Class for grabing the file frame and when I use the socket it seems that the
callback function of this class or the thread that run this class is beeing
hang because of the declering of the socket!!!

I try every thing and I think that it is a microsoft bug!!!

Do you have any idea???

Thanks!

did you try the computer name instead?
