virtual PBoolean OpalLineMediaStream::Open | ( | ) | [virtual] |
Open the media stream.
The default behaviour sets the OpalLineInterfaceDevice format and calls Resume() on the associated OpalMediaPatch thread.
Reimplemented from OpalMediaStream.
virtual PBoolean OpalLineMediaStream::Close | ( | ) | [virtual] |
virtual PBoolean OpalLineMediaStream::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 OpalLineMediaStream::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.
virtual PBoolean OpalLineMediaStream::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 OpalLineMediaStream::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 OpalLineMediaStream::SetDataSize | ( | PINDEX | dataSize | ) | [virtual] |
Set the data size in bytes that is expected to be used. Some media streams can make use of this information to perform optimisations.
The default behaviour does nothing.
dataSize | New data size |
Reimplemented from OpalMediaStream.
virtual PBoolean OpalLineMediaStream::IsSynchronous | ( | ) | const [virtual] |
Indicate if the media stream is synchronous. Returns PTrue for LID streams.
Implements OpalMediaStream.
OpalLine& OpalLineMediaStream::GetLine | ( | ) | [inline] |
Get the line being used by this media stream.
