OpalMediaStream (OpalConnection &conn, const OpalMediaFormat &mediaFormat, unsigned sessionID, bool isSource) |
This class describes a media stream that is used for media bypass.
OpalNullMediaStream::OpalNullMediaStream | ( | OpalConnection & | conn, |
const OpalMediaFormat & | mediaFormat, | ||
unsigned | sessionID, | ||
bool | isSource, | ||
bool | isSynchronous = false |
||
) |
Construct a new media stream for RTP sessions.
conn | Connection that owns the stream |
mediaFormat | Media format for stream |
sessionID | Session number for stream |
isSource | Is a source stream |
isSynchronous | Can accept data and block accordingly |

const OpalMediaFormat & | mediaFormat, | ||
unsigned | sessionID, | ||
bool | isSource, | ||
bool | usePacingDelay, | ||
bool | requiresPatchThread | ||
) |
conn | Connection that owns the stream |
mediaFormat | Media format for stream |
sessionID | Session number for stream |
isSource | Is a source stream |
usePacingDelay | Use delay to pace stream I/O |
requiresPatchThread | Requires a patch thread to execute |
|
virtual |
Indicate if the media stream is synchronous. Returns m_isSynchronous.
Implements OpalMediaStream.
|
virtual |
Read raw media data from the source media stream. The default behaviour does nothing and returns false.
data | Data buffer to read to |
size | Size of buffer |
length | Length of data actually read |
Reimplemented from OpalMediaStream.
|
virtual |
Indicate if the media stream requires a OpalMediaPatch thread (active patch). The default behaviour returns the value of m_isSynchronous.
Reimplemented from OpalMediaStream.
|
virtual |
Write raw media data to the sink media stream. The default behaviour does nothing and returns false.
data | Data to write |
length | Length of data to read. |
written | Length of data actually written |
Reimplemented from OpalMediaStream.
