Inheritance diagram for SBCDecoder:
Public Member Functions | |
| SBCDecoder (int bufferSize=8192) | |
| 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 |
| int | bytesCompressed () |
| Provides the compressed length in bytes (after encoding) | |
| int | bytesUncompressed () |
| 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 | |
Protected Member Functions | |
| int | codeSize () |
| int | firstWrite (const void *data, size_t length) |
| Determines the framelen. | |
| int | frameLength () |
| Provides the compressed length in bytes (after encoding) | |
| bool | isValidFrameLen (int len) |
| void | notifyAudioChange (AudioInfo info) |
| void | processByte (uint8_t byte) |
| Build decoding buffer and decode when frame is full. | |
| void | setupAudioInfo () |
| Process audio info. | |
| void | setupInputBuffer (int len) |
| void | writeBlocking (Print *out, uint8_t *data, size_t len) |
Protected Attributes | |
| int | framelen |

| bool | is_first = true |
| bool | is_notify_active = true |
| Vector< AudioInfoSupport * > | notify_vector |
| Print * | p_print = nullptr |
