bool MNStreamer::check_time (  const MNString &  DescFileName,
MNString &  time
)  [static]
 

virtual bool MNStreamer::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:
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 we are using a tcp or udp port solution
Returns:
true on success, false on error.

Implements dataPump.

void MNStreamer::detach (   ) 
 

void MNStreamer::examineSDP (   ) 
 

extracts bandwidth and all other information out of the given SDP

virtual void MNStreamer::fileComplete (  const char *  filename,
bool  comp
)  [virtual]
 

Reimplemented from dataPump.

virtual bool MNStreamer::fillTransportString (  int  idx,
MNString &  out,
bool  mc
)  const [virtual]
 

Writes a transport string for an SDP message, containing its specific features.

dataPump::getTransportString()

Implements dataPump.

int MNStreamer::getBandwidth (  int  idx,
const MNString &  DescFileName
) 
 

int MNStreamer::getBandwidth (  const MNString &  DescFileName  ) 
 

virtual long MNStreamer::getFilePos (   )  [virtual]
 

If the dataPump is streaming, this method returns the current time position in the source file. Else it returns -1!!

Reimplemented from dataPump.

virtual int MNStreamer::getNptSeconds (   )  [virtual]
 

Reimplemented from dataPump.

virtual int MNStreamer::init (  KomServer *  streamer,
StreamingType  type
)  [virtual]
 

Implements dataPump.

virtual bool MNStreamer::isPatchingCapable (   )  const [inline, virtual]
 

If a data pump is capable of patching support, it must overload the functions setMulticastInformation and setBufferInformation that exist only as dummy implementations in this base class. The default is that a data pump is not capable of patching.

Reimplemented from dataPump.

virtual int MNStreamer::jump (  int  cont_time  )  [virtual]
 

Reimplemented from dataPump.

virtual int MNStreamer::pause (   )  [virtual]
 

Reimplemented from dataPump.

virtual int MNStreamer::play (  int  start,
int  stop
)  [virtual]
 

Implements dataPump.

virtual void MNStreamer::set_client_port (  int  idx,
int  a
)  [inline, virtual]
 

Reimplemented from dataPump.

virtual void MNStreamer::set_client_port (  int  a  )  [inline, virtual]
 

virtual void MNStreamer::setBufferInformation (  int  threshold,
int  size
)  [virtual]
 

A dummy provided for non-patching-capable data pumps and overloaded by patching-capable data pumps.

Reimplemented from dataPump.

virtual void MNStreamer::setMulticastInformation (  int  idx,
MNString  server,
MNSocket *  main_rtp,
MNSocket *  main_rtcp
)  [virtual]
 

Stores the additional hostname and port of the server which serves the multicast stream when the proxy receives a patch stream. The information of the unicast patch stream is set through the other methods like a normal unicast session!

Changed to setting of bound sockets; if we can't bind the MC socket, we have to fall back to unicast anyway.

virtual void MNStreamer::setNptSeek (  int  npt  )  [virtual]
 

Reimplemented from dataPump.

virtual void MNStreamer::setRTPTimestamp (  int  idx,
u_int32  rtptime
)  [virtual]
 

Reimplemented from dataPump.

virtual void MNStreamer::setupExistingServerSideReflectorGM (  int  idx  )  [virtual]
 

Reimplemented from dataPump.

virtual void MNStreamer::setupNewServerSideReflectorGM (  int  idx  )  [virtual]
 

Reimplemented from dataPump.

virtual int MNStreamer::stop (   )  [virtual]
 

Implements dataPump.

virtual int MNStreamer::stream_start (  int  idx,
const MNString &  filename,
const MNString &  DescFileName,
const MNString &  client,
const MNString &  server,
int  ClientPortAnnounced,
int  ServerPortAnnounced
)  [virtual]
