Detailed Description

Information about an audio stream.

The information stored is codec-id, samplerate, samplesize, stereo, duration and codec-type.

Additionally, an abstract ExtraInfo can be hold.

Constructor & Destructor Documentation

gnash::media::AudioInfo::AudioInfo	(	int	codeci,
		boost::uint16_t	sampleRatei,
		boost::uint16_t	sampleSizei,
		bool	stereoi,
		boost::uint64_t	durationi,
		codecType	typei
	)		`[inline]`

Construct an AudioInfo object.

Parameters:

codeci	Audio codec id. To be interpreted as a media::audioCodecType if the typei parameter is CODEC_TYPE_FLASH; otherwise it's an opaque number to use for codec information transfer between a MediaParser and a AudioDecoder from the same media handler module.
sampleRatei	Nominal sample rate.

Todo:: document units.

Parameters:

sampleSizei	Sample size, in bytes.
stereoi	Sample type (stereo if true, mono otherwise).

Todo:: document if and how intepretation of sampleSizei changes

Parameters:

durationi	Nominal audio stream duration, in milliseconds.
typei	Changes interpretation of the codeci parameter.

Member Data Documentation

int gnash::media::AudioInfo::codec

Codec identifier.

This has to be interpreted as audioCodecType if codecType type is CODEC_TYPE_FLASH or interpretation is opaque and we rely on the assumption that the AudioInfo creator and the AudioInfo user have a way to get a shared interpretation
