Public Member Functions | |
| MP3DecoderMAD (libmad::MP3DataCallback dataCallback, libmad::MP3InfoCallback infoCB=nullptr) | |
| MP3DecoderMAD (Print &mad_output_streamput, libmad::MP3InfoCallback infoCB=nullptr) | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| AudioInfo | audioInfo () override |
| provides the actual input AudioInfo | |
| libmad::MadAudioInfo | audioInfoEx () |
| Provides the last valid audio information. | |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| bool | begin () |
| Starts the processing. | |
| virtual bool | begin (AudioInfo info) override |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| libmad::MP3DecoderMAD * | driver () |
| void | end () |
| Releases the reserved memory. | |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual bool | isResultPCM () |
| Returns true to indicate that the decoding result is PCM data. | |
| operator bool () | |
| Returns true as long as we are processing data. | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| void | setAudioDataCallback (libmad::MP3DataCallback cb) |
| Defines the callback which receives the decoded data. | |
| virtual void | setAudioInfo (AudioInfo from) override |
| for most decoders this is not needed | |
| void | setInfoCallback (libmad::MP3InfoCallback cb) |
| Defines the callback which receives the Info changes. | |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| virtual void | setOutput (AudioOutput &out_stream) |
| Defines where the decoded result is written to. | |
| virtual void | setOutput (AudioStream &out_stream) |
| Defines where the decoded result is written to. | |
| void | setOutput (Print &out) |
| Defines where the decoded result is written to. | |
| size_t | write (const uint8_t *data, size_t len) |
| Makes the mp3 data available for decoding: however we recommend to provide the data via a callback or input stream. | |
| size_t | write (void *data, size_t len) |
| Makes the mp3 data available for decoding: however we recommend to provide the data via a callback or input stream. | |
