Inheritance diagram for MetaDataICY:
Public Member Functions | |
| MetaDataICY (int metaint) | |
| We just process the Metadata and ignore the audio info. | |
| virtual void | begin () override |
| Resets all counters and restarts the prcessing. | |
| virtual void | end () override |
| Resets all counters and restarts the prcessing. | |
| virtual bool | hasMetaData () |
| Returns true if the ICY stream contains metadata. | |
| virtual bool | isData () |
| returns true if the actual bytes is an audio data byte (e.g.mp3) | |
| virtual int | metaInt () |
| provides the metaint | |
| virtual void | processChar (char ch) |
| character based state engine | |
| virtual void | setAudioDataCallback (void(*fn)(const uint8_t *str, int len), int bufferLen=1024) |
| Defines the audio callback function. | |
| virtual void | setCallback (void(*fn)(MetaDataType info, const char *str, int len)) override |
| Defines the metadata callback function. | |
| virtual void | setIcyMetaInt (int value) override |
| Defines the ICE metaint value which is provided by the web call! | |
| virtual Status | status () |
| Returns the actual status of the state engine for the current byte. | |
| virtual size_t | write (const uint8_t *buffer, size_t len) override |
| Writes the data in order to retrieve the metadata and perform the corresponding callbacks. | |
Protected Member Functions | |
| virtual void | clear () |
| virtual bool | isAscii (char *result, int l) |
| Make sure that the result is a valid ASCII string. | |
| virtual int | metaSize (uint8_t metaSize) |
| determines the meta data size from the size byte | |
| virtual void | processData (char ch) |
| Collects the data in a buffer and executes the callback when the buffer is full. | |
| virtual void | processMetaData (char *metaData, int len) |
| e.g. StreamTitle=' House Bulldogs - But your love (Radio Edit)';StreamUrl=''; | |
| virtual void | setupMetaData (int meta_size) |
| allocates the memory to store the metadata / we support changing sizes | |
Protected Attributes | |
| void(* | callback )(MetaDataType info, const char *str, int len) = nullptr |
| Status | currentStatus = ProcessData |
| uint8_t * | dataBuffer =nullptr |
| void(* | dataCallback )(const uint8_t *str, int len) = nullptr |
| int | dataLen = 0 |
| int | dataPos = 0 |
| bool | is_data |
| char * | metaData =nullptr |
| int | metaDataLen = 0 |
| int | metaDataMaxLen = 0 |
| int | metaDataPos = 0 |
| int | mp3_blocksize = 0 |
| Status | nextStatus = ProcessData |
| int | totalData = 0 |
