Constructor & Destructor Documentation

RTSPSourceFromAudioStream()

RTSPSourceFromAudioStream ( AudioStream &  stream )

inline

Construct a new RTSPOutputSource object from an AudioStream.

Parameters

stream

Member Function Documentation

isActive()

bool isActive ( )

inline

The active state is determined by checking if we are still getting actual read calls;

readBytes()

virtual int readBytes ( void *  dest, int  byteCount  )

inlineoverridevirtual

(Reads and) Copies up to maxSamples samples into the given buffer

Parameters

dest	Buffer into which the samples are to be copied
maxSamples	maximum number of samples to be copied

Returns

actual number of samples that were copied

setAudioInfo()

virtual void setAudioInfo ( AudioInfo  info )

inlinevirtual

Set the Audio Info. This needs to be called if we just pass a Stream. The AudioStream is usually able to provide the data from it's original configuration.

Parameters

info

start()

virtual void start ( )

inlineoverridevirtual

Start preparing data in order to provide it for the stream

stop()

virtual void stop ( )

inlineoverridevirtual

Stop preparing data as the stream has ended
