Detailed Description

A seekable audio stream.

Subclasses of this class implement an interface for seeking. The seeking itself is not required to be working while the stream is being played by the mixer.

Member Function Documentation

openStreamFile()

static SeekableAudioStream* Audio::SeekableAudioStream::openStreamFile ( const Common::Path &  basename )

static

Attempt to load a file by trying all available formats.

In case of an error, the file handle will be closed, but deleting it is still the responsibility of the caller.

Parameters

basename

File name without an extension.

Returns

A SeekableAudioStream ready to use in case of success. NULL in case of an error (e.g. invalid/non-existing file).

seek() [1/2]

bool Audio::SeekableAudioStream::seek ( uint32  where )

inline

Seek to a given offset in the stream.

Parameters

where

Offset in milliseconds.

Returns

True on success, false on failure.

seek() [2/2]

virtual bool Audio::SeekableAudioStream::seek ( const Timestamp &  where )

pure virtual

Seek to a given offset in the stream.

Parameters

where

Offset as a timestamp.

Returns

True on success, false on failure.

Implemented in Audio::SubSeekableAudioStream, Audio::Mp3PspStream, Audio::VocStream, Audio::QuickTimeAudioDecoder::QuickTimeAudioTrack, Audio::ADPCMStream, and AudioCDStream.

getLength()

virtual Timestamp Audio::SeekableAudioStream::getLength ( ) const

pure virtual

Return the length of the stream.

Returns

Length as a timestamp.

Implemented in Audio::SubSeekableAudioStream, Audio::Mp3PspStream, Audio::VocStream, Audio::QuickTimeAudioDecoder::QuickTimeAudioTrack, Audio::ADPCMStream, and AudioCDStream.

rewind()

virtual bool Audio::SeekableAudioStream::rewind ( )

inlinevirtual

Rewind the stream to its start.

Returns

True on success, false otherwise.

Implements Audio::RewindableAudioStream.

Reimplemented in Audio::ADPCMStream.
