IWMSPublishingPointLimits::put_PerPlayerConnectionBandwidth

The put_PerPlayerConnectionBandwidth method specifies the maximum bandwidth, in Kbps, permitted for a player connection on the publishing point.

HRESULT put_PerPlayerConnectionBandwidth(
  long  newVal
);

Arguments

newVal

[in] long containing the maximum bandwidth, in Kbps, permitted per player.

Return Value

If the method succeeds, it returns S_OK. If it fails, it returns an HRESULT error code.

Return code	Number	Description
E_INVALIDARG	0x80070057	Indicates that newVal is an invalid argument.

Remarks

This limit applies only to new connections. It is also used to determine the bandwidth limit for a multicast stream.

By default, the parameter is –1, indicating that there is no limit on the maximum bandwidth permitted. Valid values are –1 to 2147483647.

    // Retrieve a pointer to the IWMSPublishingPointLimits
    // interface for the publishing point.
    hr = pPubPoint->get_Limits(&pLimits);
    if (FAILED(hr)) goto EXIT;

    // Set the bandwidth limit allowed for each client connection.
    hr = pLimits->put_PerPlayerConnectionBandwidth(128);
    if (FAILED(hr)) goto EXIT;

    // Release temporary COM objects.
    pPubPoint->Release();
    pLimits->Release();
}

EXIT:
    // TODO: Release temporary COM objects and uninitialize COM.
