How to change decoder on fly with EncodedAudioStream?

[BeijingUncle]

Hi, Phil:

I'm trying to play different format audio file with EncodedAudioStream,

Here is the declare of my sketch:

A2DPStream a2dp;
MP3DecoderHelix mp3_decoder;
AACDecoderHelix aac_decoder;
WAVDecoder wav_decoder;
FLACDecoder flac_decoder;
EncodedAudioStream out2dec(&a2dp, &mp3_decoder);
StreamCopy copier(out2dec, audioFile);

but it seems there is not a method to change decoder on fly, How can I do that?

I think the best is to declare a separate EncodedAudioStream for each decoder and switch the output dynamically in the copier. For details I suggest to have a look at the class documentation of StreamCopy
