Member Function Documentation

int audiere::MP3InputStream::doRead (  int  frame_count, void *  samples )  [virtual]

Implement this method in subclasses. Implements audiere::BasicSource. Definition at line 158 of file input_mp3.cpp. References ADR_GUARD, audiere::GetFrameSize(), and audiere::QueueBuffer::getSize().

void audiere::MP3InputStream::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 146 of file input_mp3.cpp.

int audiere::MP3InputStream::getLength (   )  [virtual]

Returns: number of frames in the stream, or 0 if the stream is not seekable Reimplemented from audiere::BasicSource. Definition at line 141 of file input_mp3.cpp.

int audiere::MP3InputStream::getPosition (   )  [virtual]

Returns the current position within the sample source. Returns: current position in frames Reimplemented from audiere::BasicSource. Definition at line 97 of file input_mp3.cpp.

bool audiere::MP3InputStream::initialize (  FilePtr  file  )

Definition at line 46 of file input_mp3.cpp. References audiere::File::BEGIN, audiere::File::END, and reset().

bool audiere::MP3InputStream::isSeekable (   )  [virtual]

Returns: true if the stream is seekable, false otherwise Reimplemented from audiere::BasicSource. Definition at line 92 of file input_mp3.cpp.

void audiere::MP3InputStream::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 197 of file input_mp3.cpp. References ADR_GUARD, audiere::File::BEGIN, and audiere::QueueBuffer::clear(). Referenced by initialize(), and setPosition().

void audiere::MP3InputStream::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 102 of file input_mp3.cpp. References audiere::File::BEGIN, and reset().
