IRTCSession::AddStream

  • Article

This method adds one new stream to this session. The session must be in the RTCSS_CONNECTED or RTCSS_INPROGRESS state. The call will start a renegotiation with the other end of the call, and an RTCE_SESSION_STATE_CHANGE event will be triggered.

HRESULT AddStream(
  long lMediaType,
  LONG_PTR lCookie
);

Parameters

  • lMediaType
    [in] An RTCMT_ constant specifying the media for which the stream will be added. The application can add only one stream at a time. Windows CE does not support RTCMT_VIDEO_SEND, RTCMT_VIDEO_RECEIVE and RTCMT_T120_SENDRECV media types.
  • lCookie
    [in] Pointer to an application-provided cookie used in the completion notification.

Return Values

Value Description
