virtual bool MNDummyStreamer::createDownstreamSocks (  int  idx,
int &  requested,
RTPSockets::FactoryMode  mode,
RTSP::TransportTypes  requested_transport = RTSP::RTP_AVP_UDP
)  [virtual]
 

The data pump tries to create the requested socket as an RTP socket, with the matching RTCP socket as well. The mode determines whether the actual port may differ, and whether the RTCP socket must exist or not. On return, the actually allocated port is returned in the parameter requested.

Parameters:
idx Index into the socket vector.
requested On input, the requested port. On output and in case of success, the actually opened port.
mode DEFAULT indicates that any pair of ports can be opened, FIXED indicates that only the requested port is OK, RTCP_FAIL_OK indicates that only the RTP port is really required.
requested_transport Informs if the ports are UDP or TCP.
Returns:
true on success, false on error.

Implements dataPump.

virtual bool MNDummyStreamer::createUpstreamSocks (  int  idx,
int &  requested,
RTPSockets::FactoryMode  mode,
RTSP::TransportTypes  requested_transport = RTSP::RTP_AVP_UDP
)  [virtual]
 

The data pump tries to create the requested socket as an RTP socket, with the matching RTCP socket as well. The mode determines whether the actual port may differ, and whether the RTCP socket must exist or not. On return, the actually allocated port is returned in the parameter requested.

Parameters:
idx Index into the socket vector.
requested On input, the requested port. On output and in case of success, the actually opened port.
mode DEFAULT indicates that any pair of ports can be opened, FIXED indicates that only the requested port is OK, RTCP_FAIL_OK indicates that only the RTP port is really required.
requested_transport Translated to an enum for the RTSP transport specification. Usually 1 for RTP/AVP/UDP.
Returns:
true on success, false on error.

Implements dataPump.

virtual bool MNDummyStreamer::fillTransportString (  int  idx,
MNString &  out,
bool  multicast
)  const [virtual]
 

When the proxy must formulate a SETUP response for the client, the Transport line must be created. Since the transport protocol is only known to the specific data pump, the data pump is the entity that should write this string.

Parameters:
out Out parameter containing the transport string that is fill by the specific data pump.
mc In parameter telling the data pump that it should assume multicast or unicast, respectively. The necessity of this parameter is a design flaw, because this information is exchange with the data pump far too late.
Returns:
True, if the transport string was successfully filled in, false otherwise.

Implements dataPump.
