EncoderBase64 Class Reference

EncoderBase64s - Encodes the input data into a Base64 string. By default each audio frame is followed by a new line, so that we can easily resynchronize the reading of a data stream. The generation of the new line can be configured with the setNewLine() method. More...

Public Member Functions

 EncoderBase64 (Print &out)
 
AudioInfo audioInfo ()
 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
 
virtual bool begin () override
 starts the processing using the actual RAWAudioInfo
 
virtual bool begin (AudioInfo info)
 
void end () override
 stops the processing
 
bool isOpen ()
 
const char * mime () override
 Provides "text/base64".
 
 operator bool () override
 
void setAudioInfo (AudioInfo from) override
 Defines the sample rate, number of channels and bits per sample.
 
void setNewLine (Base46Logic flag)
 We add a new line after each write.
 
void setOutput (Print &out_buffeream) override
 Defines the output Stream.
 
virtual size_t write (const uint8_t *data, size_t len) override
 Writes PCM data to be encoded as RAW.
