Function Documentation

struct SimpleAudioPacket __attribute__

(

(packed)

)

static cardinal __attribute__::calculateFrameSize	(	const cardinal	inputBytesPerSecond,
		const cardinal	inputFrameSize
	)		[static]

Calculate output frame size from given input bytes per second and input frame size.

Parameters:

inputBytesPerSecond	Input source's bytes per second.
inputFrameSize	Input source's frame size.

Returns:

The calculated frame size.

static AudioQuality __attribute__::calculateQualityForLimits	(	const AudioQualityInterface &	userSetting,
		const AudioQualityInterface &	inputQuality,
		const card64	totalByteRateLimit,
		const cardinal	networkQualityDecrement,
		const cardinal	headerSize,
		const cardinal	maxPacketSize
	)		[static]

Quality calculation for given user quality limited by input quality, byte rate and network quality decrement with given header size (eg. IP + UDP + RTP) and maximum packet size.

Parameters:

userSetting	User's quality setting.
inputQuality	Input source's quality.
byteRateLimit	Byte rate limit.
networkQualityDecrement	Number of steps for decrement of user's quality.
headerSize	Header size (eg. IP + UDP + RTP). SimpleAudioPacket size is added automatically.
maxPacketSize	Maximum packet size.

Returns:

The calculated quality.

void __attribute__::reset

(

)

Reset report.

__attribute__::SimpleAudioPacket

(

)

Constructor.

void __attribute__::translate

(

)
