Member Function Documentation

◆ onAudioRead()

bool vrs_sample_apps::AudioStreamPlayer::onAudioRead	(	const CurrentRecord &	record,
		size_t	blockIndex,
		const ContentBlock &	cb
	)

inlineoverridevirtual

Callback for audio content blocks. The ContentBlock object 'cb' describes the audio content block, but the content block's data has not been read yet. Query the ContentBlock object to know the details about the audio data and the content block's size. Then you can allocate or reuse a buffer, and call record.reader->read() to read the content block's data in that buffer.

Parameters

record	Metadata associated with the record being read.
blockIndex	Index of the content block being read.
cb	ContentBlock describing the audio data to be read.

Returns: Return true if remaining record content blocks should be read.

Reimplemented from vrs::RecordFormatStreamPlayer.
