Detailed Description

template<typename FileT>
class audio_tools::AudioPlayerMimeSourceFromFile< FileT >

MimeSource that determines the mime type from the file name extension of the file that an AudioPlayer is currently playing.

Intended to be used together with a MultiDecoder (via MultiDecoder::setMimeSource()) whenever the AudioPlayer's AudioSource is disk based (e.g. AudioSourceSDMMC, AudioSourceSD, AudioSourceSDFAT, AudioSourceSPIFFS, AudioSourceLittleFS, AudioSourceVFS, ...). The decoder is then selected from the file name extension instead of relying on (potentially ambiguous or slower) content sniffing.

AudioSourceSDMMC source(...);
MultiDecoder multiDecoder;
AudioPlayer player(source, out, multiDecoder);
AudioPlayerMimeSourceFromFile<fs::File> mimeFromFile(player);
multiDecoder.setMimeSource(mimeFromFile);

Template Parameters

FileT

the File type returned by the AudioSource in use (e.g. fs::File for AudioSourceSD/AudioSourceSDMMC). The type must provide a name() method that returns the (base) file name.

Member Function Documentation

mime()

template<typename FileT >

const char * mime ( )

inlineoverridevirtual

Determines the mime type from the extension of the currently playing file. Returns nullptr if no file is active or the extension is unknown.

Implements MimeSource.

mimeResolver()

template<typename FileT >

MimeResolver & mimeResolver ( )

inline

Provides access to the mime resolver, e.g. to register additional extension -> mime mappings via addMimeEntry().
