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 PPB_ElementaryStream_Samsung.InitializeDone.

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

Member Data Documentation

PP_AudioCodec_Profile_Samsung(* PPB_AudioElementaryStream_Samsung_1_0::GetAudioCodecProfile)(PP_Resource stream)

Retrieves current audio codec profile.

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

Current audio codec profile.

PP_AudioCodec_Type_Samsung(* PPB_AudioElementaryStream_Samsung_1_0::GetAudioCodecType)(PP_Resource stream)

Retrieves current audio codec type.

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

Current audio codec type.

int32_t(* PPB_AudioElementaryStream_Samsung_1_0::GetBitsPerChannel)(PP_Resource stream)

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

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

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

PP_ChannelLayout_Samsung(* PPB_AudioElementaryStream_Samsung_1_0::GetChannelLayout)(PP_Resource stream)

Retrieves current audio channel layout.

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

current audio channel layout.

PP_SampleFormat_Samsung(* PPB_AudioElementaryStream_Samsung_1_0::GetSampleFormat)(PP_Resource stream)

Retrieves current audio sample format.

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

Current audio sample format.

int32_t(* PPB_AudioElementaryStream_Samsung_1_0::GetSamplesPerSecond)(PP_Resource stream)

Retrieves how many audio samples were recorded per second (sample rate).

Parameters

[in]

stream

A PP_Resource identifying the audio elementary stream.

Returns

Current audio samples per second.

PP_Bool(* PPB_AudioElementaryStream_Samsung_1_0::IsAudioElementaryStream)(PP_Resource resource)

Determines if the given resource is an audio elementary stream.

Parameters

[in]

resource

A PP_Resource identifying a resource.

Returns

PP_TRUE if the resource is a PPB_AudioElementaryStream_Samsung, PP_FALSE if the resource is invalid or some other type.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetAudioCodecProfile)(PP_Resource stream, PP_AudioCodec_Profile_Samsung profile)

Sets 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.

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	profile	New audio codec profile.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetAudioCodecType)(PP_Resource stream, PP_AudioCodec_Type_Samsung audio_codec)

Sets new audio codec type.

Remarks

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

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	audio_codec	New audio codec type.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetBitsPerChannel)(PP_Resource stream, 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.

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	bits_per_channel	Value representing how many bits are used to represent audio sample per each channel.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetChannelLayout)(PP_Resource stream, PP_ChannelLayout_Samsung channel_layout)

Sets new audio channel layout.

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	audio_codec	New audio channel layout.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetCodecExtraData)(PP_Resource stream, 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]	stream	A PP_Resource identifying the audio elementary stream.
[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.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetSampleFormat)(PP_Resource stream, PP_SampleFormat_Samsung sample_format)

Sets 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.

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	sample_format	New audio sample format.

void(* PPB_AudioElementaryStream_Samsung_1_0::SetSamplesPerSecond)(PP_Resource stream, int32_t samples_per_second)

Sets how many audio samples were recorded per second (sample rate).

Parameters

[in]	stream	A PP_Resource identifying the audio elementary stream.
[in]	samples_per_second	Value representing audio samples per second.
