nsWaveDecoder provides an implementation of the abstract nsMediaDecoder
class that supports parsing and playback of Waveform Audio (WAVE) chunks
embedded in Resource Interchange File Format (RIFF) bitstreams as
specified by the Multimedia Programming Interface and Data Specification
1.0.
Each decoder instance starts one thread (the playback thread). A single
nsWaveStateMachine event is dispatched to this thread to start the
thread's state machine running. The Run method of the event is a loop
that executes the current state. The state can be changed by the state
machine, or from the main thread via threadsafe methods on the event.
During playback, the playback thread reads data from the network and
writes it to the audio backend, attempting to keep the backend's audio
buffers full. It is also responsible for seeking, buffering, and
pausing/resuming audio.
The decoder also owns an nsMediaStream instance that provides a threadsafe
blocking interface to read from network channels. The state machine is
the primary user of this stream and holds a weak (raw) pointer to it as
the thread, state machine, and stream's lifetimes are all managed by the
decoder.
nsWaveStateMachine has the following states:
LOADING_METADATA
RIFF/WAVE chunks are being read from the stream, the metadata describing
the audio data is parsed.
BUFFERING
Playback is paused while waiting for additional data.
PLAYING
If data is available in the stream and the audio backend can consume
more data, it is read from the stream and written to the audio backend.
Sleep until approximately half of the backend's buffers have drained.
SEEKING
Decoder is seeking to a specified time in the media.
PAUSED
Pause the audio backend, then wait for a state transition.
ENDED
Expected PCM data (or stream EOF) reached, wait for the audio backend to
play any buffered data, then wait for shutdown.
ERROR
Metadata loading/parsing failed, wait for shutdown.
SHUTDOWN
Close the audio backend and return from the run loop.
State transitions within the state machine are:
LOADING_METADATA -> PLAYING
-> PAUSED
-> ERROR
BUFFERING -> PLAYING
-> PAUSED
PLAYING -> BUFFERING
-> ENDED
SEEKING -> PLAYING
-> PAUSED
PAUSED -> waits for caller to play, seek, or shutdown
ENDED -> waits for caller to shutdown
ERROR -> waits for caller to shutdown
SHUTDOWN -> exits state machine
In addition, the following methods cause state transitions:
Shutdown(), Play(), Pause(), Seek(float)
The decoder implementation is currently limited to Linear PCM encoded
audio data with one or two channels of 16-bit samples at sample rates from
100 Hz to 96 kHz. The sample size and number of channels (and, to some
extent, the sample format) is limited by what the audio backend
(sydneyaudio via nsAudioStream) currently supports. sydneyaudio's API
suggests support of 8-bit, µ-Law, and A-Law samples, but this support is
not currently implemented. The supported sample rate is artificially
limited to arbitrarily selected sane values. Support for additional
channels (and other new features) would require extending nsWaveDecoder to
support parsing the newer WAVE_FORMAT_EXTENSIBLE chunk format.
