Member Data Documentation

void*(* PPB_AudioBuffer_0_1::GetDataBuffer)(PP_Resource buffer)

Gets the data buffer containing the audio samples.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

A pointer to the beginning of the data buffer.

Definition at line 138 of file ppb_audio_buffer.h.

uint32_t(* PPB_AudioBuffer_0_1::GetDataBufferSize)(PP_Resource buffer)

Gets the size of the data buffer in bytes.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

The size of the data buffer in bytes.

Definition at line 147 of file ppb_audio_buffer.h.

uint32_t(* PPB_AudioBuffer_0_1::GetNumberOfChannels)(PP_Resource buffer)

Gets the number of channels in the audio buffer.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

The number of channels in the audio buffer.

Definition at line 118 of file ppb_audio_buffer.h.

uint32_t(* PPB_AudioBuffer_0_1::GetNumberOfSamples)(PP_Resource buffer)

Gets the number of samples in the audio buffer.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

The number of samples in the audio buffer. For example, at a sampling rate of 44,100 Hz in stereo audio, a buffer containing 4410 * 2 samples would have a duration of 100 milliseconds.

Definition at line 129 of file ppb_audio_buffer.h.

PP_AudioBuffer_SampleRate(* PPB_AudioBuffer_0_1::GetSampleRate)(PP_Resource buffer)

Gets the sample rate of the audio buffer.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

The sample rate of the audio buffer.

Definition at line 100 of file ppb_audio_buffer.h.

PP_AudioBuffer_SampleSize(* PPB_AudioBuffer_0_1::GetSampleSize)(PP_Resource buffer)

Gets the sample size of the audio buffer.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

The sample size of the audio buffer.

Definition at line 109 of file ppb_audio_buffer.h.

PP_TimeDelta(* PPB_AudioBuffer_0_1::GetTimestamp)(PP_Resource buffer)

Gets the timestamp of the audio buffer.

Parameters

[in]

buffer

A PP_Resource corresponding to an audio buffer resource.

Returns

A PP_TimeDelta containing the timestamp of the audio buffer. Given in seconds since the start of the containing audio stream.

Definition at line 81 of file ppb_audio_buffer.h.

PP_Bool(* PPB_AudioBuffer_0_1::IsAudioBuffer)(PP_Resource resource)

Determines if a resource is an AudioBuffer resource.

Parameters

[in]

resource

The PP_Resource to test.

Returns

A PP_Bool with PP_TRUE if the given resource is an AudioBuffer resource or PP_FALSE otherwise.

Definition at line 71 of file ppb_audio_buffer.h.

void(* PPB_AudioBuffer_0_1::SetTimestamp)(PP_Resource buffer, PP_TimeDelta timestamp)

Sets the timestamp of the audio buffer.

Parameters

[in]	buffer	A PP_Resource corresponding to an audio buffer resource.
[in]	timestamp	A PP_TimeDelta containing the timestamp of the audio buffer. Given in seconds since the start of the containing audio stream.
