| default constructor | |
| virtual | ~SPDIFOutput () |
| destructor | |
| virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
| Adds target to be notified about audio changes. | |
| virtual AudioInfo | audioInfo () override |
| 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 int | available () override |
| virtual int | availableForWrite () override |
| bool | begin () |
| Starting with last or default settings. | |
| bool | begin (SPDIFConfig config) |
| Start with the provided parameters. | |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| SPDIFConfig | defaultConfig () |
| Provides the default configuration. | |
| void | end () |
| virtual void | flush () override |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual | operator bool () |
| virtual size_t | readBytes (uint8_t *data, size_t len) override |
| virtual size_t | readSilence (uint8_t *buffer, size_t length) |
| Source to generate silence: just sets the buffer to 0. | |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| void | setAudioInfo (AudioInfo info) |
| Change the audio parameters. | |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| size_t | write (const uint8_t *data, size_t len) |
| Writes the audio data as SPDIF to the defined output pin. | |
| virtual size_t | write (uint8_t ch) override |
| virtual void | writeSilence (size_t len) |
| Writes len bytes of silence (=0). | |
