Inheritance diagram for MetaDataOutput:
Public Member Functions | |
| MetaDataOutput (MetaDataOutput const &)=delete | |
| 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 | availableForWrite () override |
| virtual bool | begin () |
| virtual bool | begin (AudioInfo info) |
| virtual void | begin (HttpRequest &http) |
| Starts the processing - iceMetaint is determined from the HttpRequest. | |
| virtual void | begin (int iceMetaint=0) |
| Starts the processing - if iceMetaint is defined we use icecast. | |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| virtual void | end () |
| virtual void | flush () |
| virtual bool | isDeletable () |
| If true we need to release the related memory in the destructor. | |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual | operator bool () |
| MetaDataOutput & | operator= (MetaDataOutput const &)=delete |
| virtual bool | removeNotifyAudioChange (AudioInfoSupport &bi) |
| Removes a target in order not to be notified about audio changes. | |
| virtual void | setAudioInfo (AudioInfo newInfo) override |
| Defines the input AudioInfo. | |
| virtual void | setCallback (void(*fn)(MetaDataType info, const char *str, int len)) |
| Defines the callback. | |
| void | setNotifyActive (bool flag) |
| Deactivate/Reactivate automatic AudioInfo updates: (default is active) | |
| virtual size_t | write (const uint8_t *data, size_t len) |
| Provide tha audio data to the API to parse for Meta Data. | |
| virtual size_t | write (uint8_t c) |
| virtual void | writeSilence (size_t len) |
