Public Member Functions | |
virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
Adds target to be notified about audio changes. | |
virtual 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 () |
virtual bool | begin (AudioInfo info) override |
virtual void | clearNotifyAudioChange () |
Deletes all change notify subscriptions. | |
virtual void | end () |
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 () | |
virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
Removes a target in order not to be notified about audio changes. | |
virtual void | setAudioInfo (AudioInfo from) override |
for most decoders this is not needed | |
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. | |
virtual void | setOutput (Print &out_stream) |
Defines where the decoded result is written to. | |
virtual size_t | write (const uint8_t *data, size_t len) |
Public Attributes | |
int | id |
custom id to be used by application | |
