OpalLocalMediaStream::OpalLocalMediaStream | ( | OpalLocalConnection & | conn, | |
const OpalMediaFormat & | mediaFormat, | |||
unsigned | sessionID, | |||
bool | isSource, | |||
OpalLocalEndPoint::Synchronicity | synchronicity | |||
) |
Construct a new media stream for local system.
conn | Connection for media stream |
mediaFormat | Media format for stream |
sessionID | Session number for stream |
isSource | Is a source stream |
synchronicity | Synchronous mode |
virtual void OpalLocalMediaStream::InternalClose | ( | ) | [inline, protected, virtual] |
Close any internal components of the stream. This should be used in preference to overriding the Close() function as it is guaranteed to be called exactly once and avoids race conditions in the shut down sequence of a media stream.
Implements OpalMediaStream.
virtual PBoolean OpalLocalMediaStream::IsSynchronous | ( | ) | const [virtual] |
Indicate if the media stream is synchronous. Returns true for LID streams.
Implements OpalMediaStream.
virtual PBoolean OpalLocalMediaStream::ReadData | ( | BYTE * | data, | |
PINDEX | size, | |||
PINDEX & | length | |||
) | [virtual] |
Read raw media data from the source media stream. The default behaviour reads from the OpalLine object.
data | Data buffer to read to |
size | Size of buffer |
length | Length of data actually read |
Reimplemented from OpalMediaStream.
virtual PBoolean OpalLocalMediaStream::ReadPacket | ( | RTP_DataFrame & | packet | ) | [virtual] |
Read an RTP frame of data from the source media stream. The default behaviour simply calls ReadData() on the data portion of the RTP_DataFrame and sets the frames timestamp and marker from the internal member variables of the media stream class.
Reimplemented from OpalMediaStream.
virtual PBoolean OpalLocalMediaStream::WriteData | ( | const BYTE * | data, | |
PINDEX | length, | |||
PINDEX & | written | |||
) | [virtual] |
Write raw media data to the sink media stream. The default behaviour writes to the OpalLine object.
data | Data to write |
length | Length of data to read. |
written | Length of data actually written |
Reimplemented from OpalMediaStream.
virtual PBoolean OpalLocalMediaStream::WritePacket | ( | RTP_DataFrame & | packet | ) | [virtual] |
Write an RTP frame of data to the sink media stream. The default behaviour simply calls WriteData() on the data portion of the RTP_DataFrame and and sets the internal timestamp and marker from the member variables of the media stream class.
Reimplemented from OpalMediaStream.
