OpalMediaStream (OpalConnection &conn, const OpalMediaFormat &mediaFormat, unsigned sessionID, bool isSource) |
Local media stream. This class represents a media stream on the local machine that can receive media via virtual functions.
OpalLocalMediaStream::OpalLocalMediaStream | ( | OpalLocalConnection & | conn, |
const OpalMediaFormat & | mediaFormat, | ||
unsigned | sessionID, | ||
bool | isSource, | ||
bool | isSynchronous | ||
) |
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 |
isSynchronous | Can accept data and block accordingly |
|
virtual |
Indicate if the media stream is synchronous. Returns true for LID streams.
Implements OpalMediaStream.
|
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 |
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 |
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 |
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.
