Syntax

HRESULT RemoveStream(
  long lMediaType,
  LONG_PTR lCookie
);

Parameters

• lMediaType
  [in] RTCMT_ constant specifying the media type for which to remove the stream. Only one stream can be removed by this call.

  Windows Embedded CE does not support RTCMT_VIDEO_SEND, RTCMT_VIDEO_RECEIVE and RTCMT_T120_SENDRECV media types.

Return Value

The following table shows additional information about specific return values.

Remarks

For RTC Client API version 1.2, this method can be called multiple times to remove all media streams from the session.

For the RTC version 1.0 API, this method can be used to remove all but one media stream.

This method will remove the media type specified in the IRTCClient::SetPreferredMediaTypes method.

Security Note:
This method can send data over the network in unencrypted form. Therefore, someone eavesdropping on the network might be able to read the data. Before using this method in an unencrypted session, consider the security risk of sending the data in clear text. The application can encrypt an RTC session by specifying TLS in the profile used for the session.
