NW Renderer: put_MaxTCPConnections failed

[FS7]

Hi,

what is wrong? Below my code:

// Init
CComQIPtr<IMVNetworkRenderer4> pNWRenderer = m_pIFilterGraph->GetFilter( szFilter.AllocSysString() );

// Set Protocol
hr =pNWRenderer->put_Protocol(MV_NETWORK_PROTOCOL_TCP);
if( FAILED( hr ) ) {
strError.Format("(Error %x)", hr);
}

// Set Max TCPConnections
LONG lMaxTCPConnections=1;
hr =pNWRenderer->put_MaxTCPConnections(lMaxTCPConnections);
if( FAILED( hr ) ) {
strError.Format("(Error %x)", hr);
}


HRESULT = 80070057
->An invalid parameter was passed to the returning function

But i don't think so: The function expects LONG an passed LONG!

Best Regards
Fabian

Hi

The invalid parameter means hat the parameter is out of range. The range for MaxTCPConnections is 1 to 999. Do you really pass 1 to this property or did you simlify the code for this post?

Hi,

no i pass 1 to this property!

Here is the entire code:

HRESULT CLocalCamera::setNWRendererSettings(CString szFilter, int iPort, CString strRemoteHost)
{
HRESULT hr = E_FAIL;

if(!m_pIFilterGraph)
return hr;

CString strError;
try
{
CComQIPtr<IMVNetworkRenderer4> pNWRenderer = m_pIFilterGraph->GetFilter( szFilter.AllocSysString() );

if(!pNWRenderer)
return hr;

hr =pNWRenderer->put_ClientAddress(strRemoteHost.AllocSysString());
if( FAILED( hr ) )
{
strError.Format("Port:%i; RemoteHost:%s; (Error %x)",PORT_VIDEO, strRemoteHost, hr);
CAISRemoteExperteApp::m_Log.WriteLine("[Fehler]\t [setNWRendererSettings]: Kamera - put_ClientAddress! " + strError);
return hr;
}
hr =pNWRenderer->put_Description(L"");
if( FAILED( hr ) )

Hi!

Ignore the return value. The filter always returns E_INVALIDARG. If the value within the range from 1 to 999 the filter accepts the value.
