Member Function Documentation

int audiere::SpeexInputStream::doRead (  int  frame_count, void *  buffer )  [virtual]

Implement this method in subclasses. Implements audiere::BasicSource. Definition at line 108 of file input_speex.cpp. References ADR_ASSERT, audiere::QueueBuffer::getSize(), audiere::QueueBuffer::read(), and audiere::QueueBuffer::write().

void audiere::SpeexInputStream::getFormat (  int &  channel_count, int &  sample_rate, SampleFormat &  sample_format )  [virtual]

Retrieve the number of channels, sample rate, and sample format of the sample source. Implements audiere::SampleSource. Definition at line 96 of file input_speex.cpp. References audiere::SF_S16.

int audiere::SpeexInputStream::getLength (   )  [virtual]

Returns: number of frames in the stream, or 0 if the stream is not seekable Reimplemented from audiere::BasicSource. Definition at line 157 of file input_speex.cpp.

int audiere::SpeexInputStream::getPosition (   )  [virtual]

Returns the current position within the sample source. Returns: current position in frames Reimplemented from audiere::BasicSource. Definition at line 170 of file input_speex.cpp.

bool audiere::SpeexInputStream::initialize (  FilePtr  file  )

Todo: this really should be replaced with a factory function Definition at line 60 of file input_speex.cpp.

bool audiere::SpeexInputStream::isSeekable (   )  [virtual]

Returns: true if the stream is seekable, false otherwise Reimplemented from audiere::BasicSource. Definition at line 151 of file input_speex.cpp.

void audiere::SpeexInputStream::reset (   )  [virtual]

Reset the sample source. This has the same effect as setPosition(0) on a seekable source. On an unseekable source, it resets all internal state to the way it was when the source was first created. Implements audiere::SampleSource. Definition at line 145 of file input_speex.cpp. References setPosition().

void audiere::SpeexInputStream::setPosition (  int  position  )  [virtual]

Sets the current position within the sample source. If the stream is not seekable, this method does nothing. Parameters: position  current position in frames Reimplemented from audiere::BasicSource. Definition at line 163 of file input_speex.cpp. Referenced by reset().
