Member Typedef Documentation

typedef std::list<EmbedSoundInst*> gnash::sound::EmbedSound::Instances

Vector containing the active instances of this sounds being played.

NOTE: This class does NOT own the active sounds

---

Constructor & Destructor Documentation

gnash::sound::EmbedSound::EmbedSound	(	std::auto_ptr< SimpleBuffer >	data,
		const media::SoundInfo &	info,
		int	volume
	)

Construct a sound with given data, info and volume.

Parameters:

	data	The encoded sound data.
	info	encoding info
	volume	initial volume (0..100). Optional, defaults to 100.

References data, and volume.

Member Function Documentation

void gnash::sound::EmbedSound::clearInstances

(

)

Drop all active sounds.

Locks _soundInstancesMutex

References _buf.

Referenced by eraseActiveSound().

std::auto_ptr< EmbedSoundInst > gnash::sound::EmbedSound::createInstance	(	media::MediaHandler &	mh,
		unsigned int	inPoint,
		unsigned int	outPoint,
		const SoundEnvelopes *	envelopes,
		unsigned int	loopCount
	)

Create an instance of this sound.

The returned instance ownership is transferred

Parameters:

	mh	The MediaHandler to use for on-demand decoding
	inPoint	Offset in output samples this instance should start playing from. These are post-resampling samples from the start of the specified blockId.
	outPoint	Offset in output samples this instance should stop playing at. These are post-resampling samples from the start of the specified blockId.
	envelopes	SoundEnvelopes to apply to this sound. May be 0 for none.
	loopCount	Number of times this instance should loop over the defined sound.

Todo:

document if every loop starts at secsOffset ! Locks the _soundInstancesMutex when pushing to it

const boost::uint8_t* gnash::sound::EmbedSound::data

(

size_t

pos

)

const [inline]

Return a pointer to an offset in the underlying buffer.

Parameters:

pos

The offset value. An assertion will fail if pos > size()

References assert, and size().

const boost::uint8_t* gnash::sound::EmbedSound::data

(

)

const [inline]

Return a pointer to the underlying buffer.

bool gnash::sound::EmbedSound::empty

(

)

const [inline]

Is the data buffer empty ?

EmbedSound::Instances::iterator gnash::sound::EmbedSound::eraseActiveSound

(

Instances::iterator

i

)

Drop an active sound (by iterator).

Does *NOT* lock the _soundInstancesMutex

Returns:

iterator after the one being erased

void gnash::sound::EmbedSound::eraseActiveSound

(

EmbedSoundInst *

inst

)

Drop an active sound (by pointer).

Parameters:

inst

The active sound instance to unregister

This is intended to be called by EmbedSoundInst destructor, which may be called by a separate thread so MUST be thread-safe

Does lock the _soundInstancesMutex

Todo:

make private and mark EmbedSoundInst as friend ?

References clearInstances().

EmbedSoundInst * gnash::sound::EmbedSound::firstPlayingInstance

(

)

const

Return the first created instance of this sound.

Locks _soundInstancesMutex

void gnash::sound::EmbedSound::getPlayingInstances

(

std::vector< InputStream * > &

to

)

const

Append to the given vector all playing instances of this sound def.

bool gnash::sound::EmbedSound::isPlaying

(

)

const

Are there known playing instances of this sound ?

Locks _soundInstancesMutex

size_t gnash::sound::EmbedSound::numPlayingInstances

(

)

const

Return number of playing instances of this sound.

Locks _soundInstancesMutex

size_t gnash::sound::EmbedSound::size

(

)

const [inline]

Return size of the data buffer.
