BinaryContainerEncoder Class Reference

Wraps the encoded data into Config, Data, and Meta segments so that we can recover the audio configuration and orignial segments if this is relevant. We assume that a full segment is written with each call of write(); The segments are separated with a new line character. More...

Inheritance diagram for BinaryContainerEncoder:

Public Member Functions
	BinaryContainerEncoder (AudioEncoder &encoder)
	BinaryContainerEncoder (AudioEncoder *encoder)
AudioInfo	audioInfo () override
	provides the actual input AudioInfo
virtual AudioInfo	audioInfoOut ()
	provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream
bool	begin () override
virtual bool	begin (AudioInfo info)
void	end ()
virtual const char *	mime ()
	Provides the mime type of the encoded result.
	operator bool ()
void	setAudioInfo (AudioInfo info) override
	Defines the sample rate, number of channels and bits per sample.
void	setEncoder (AudioEncoder *encoder)
void	setOutput (Print &outStream)
size_t	write (const uint8_t *data, size_t len)
	Add data segment. On first write we also add a AudioInfo header.
size_t	writeMeta (const uint8_t *data, size_t len)
	Adds meta data segment.

Detailed Description

Wraps the encoded data into Config, Data, and Meta segments so that we can recover the audio configuration and orignial segments if this is relevant. We assume that a full segment is written with each call of write(); The segments are separated with a new line character.
