We can write PCM data to the RTSPOutput. This is encoded by the indicated encoder (e.g. SBCEncoder) and can be consumed by a RTSPServer. You have to make sure that the codec supports the provided audio format: e.g. GSM support only 8000 samples per second with one channel.

Member Function Documentation

◆ availableForWrite()

int availableForWrite ( )

inlinevirtual

We do not know exactly how much we can write because the encoded audio is using less space. But providing the available buffer should cover the worst case.

Reimplemented from AudioOutput.

◆ write()

size_t write	(	const uint8_t *	buffer,
		size_t	byteCount
	)

inlineoverridevirtual

We write PCM data which is encoded on the fly by the indicated encoder. This data is provided by the IAudioSource

Implements AudioOutput.

◆ writeSilence()

virtual void writeSilence ( size_t len )

inlinevirtualinherited

Writes n 0 values (= silence)

Parameters

len
