Detailed Description

Interface representing an audio elementary stream and containing methods to set audio codec specific configuration.

All pending configuration changes/initialization must be confirmed by call to ElementaryStream.InitializeDone.

All getters return last set configuration, which might be not confirmed yet.

Member Function Documentation

GetBitsPerChannel()

int32_t Samsung::NaClPlayer::AudioElementaryStream::GetBitsPerChannel

(

)

const

Retrieves a currently set number of bits that are used to represent audio sample per each channel.

GetStreamType()

virtual ElementaryStreamType Samsung::NaClPlayer::AudioElementaryStream::GetStreamType ( ) const

virtual

Retrieves stream type represented by this resource, in this case ElementaryStream::Audio.

Implements Samsung::NaClPlayer::ElementaryStream.

SetAudioCodecProfile()

void Samsung::NaClPlayer::AudioElementaryStream::SetAudioCodecProfile

(

AudioCodec_Profile

profile

)

Sets a new audio codec profile.

Remarks

This parameter can be figured out by the platform most of the times and therefore isn't mandatory to set for all configurations.

SetAudioCodecType()

void Samsung::NaClPlayer::AudioElementaryStream::SetAudioCodecType

(

AudioCodec_Type

audio_codec

)

Sets a new audio codec type.

Remarks

This is a mandatory parameter which must be set for every stream.

SetBitsPerChannel()

void Samsung::NaClPlayer::AudioElementaryStream::SetBitsPerChannel

(

int32_t

bits_per_channel

)

Sets how many bits are used to represent audio sample per each channel.

Remarks

This parameter can be figured out by the platform most of the times and therefore isn't mandatory to set for all configurations.

SetCodecExtraData()

void Samsung::NaClPlayer::AudioElementaryStream::SetCodecExtraData	(	uint32_t	extra_data_size,
		const void *	extra_data
	)

Sets audio codec specific extra data. Those data are needed by audio codec to initialize properly audio decoding.

Parameters

[in]	extra_data_size	Size in bytes of extra_data buffer.
[in]	extra_data	A pointer to the buffer containing audio codec specific extra data.

SetSampleFormat()

void Samsung::NaClPlayer::AudioElementaryStream::SetSampleFormat

(

SampleFormat

sample_format

)

Sets a new audio sample format.

Remarks

This parameter can be figured out by the platform most of the times. It must be set explictly only for PCM and MULAW audio streams.
