Public Member Functions | |
| AACDecoderFDK (int output_buffer_size=2048) | |
| AACDecoderFDK (Print &out_stream, int output_buffer_size=2048) | |
| void | addNotifyAudioChange (AudioInfoSupport &bi) override |
| Adds target to be notified about audio changes. | |
| AudioInfo | audioInfo () override |
| provides the actual input AudioInfo | |
| CStreamInfo | audioInfoEx () |
| virtual AudioInfo | audioInfoOut () |
| provides the actual output AudioInfo: this is usually the same as audioInfo() unless we use a transforming stream | |
| bool | begin () |
| virtual bool | begin (AudioInfo info) override |
| bool | begin (TRANSPORT_TYPE transportType, UINT nrOfLayers) |
| virtual void | clearNotifyAudioChange () |
| Deletes all change notify subscriptions. | |
| AAC_DECODER_ERROR | configure (uint8_t *conf, const uint32_t &length) |
| Explicitly configure the decoder by passing a raw AudioSpecificConfig (ASC) or a StreamMuxConfig (SMC), contained in a binary buffer. This is required for MPEG-4 and Raw Packets file format bitstreams as well as for LATM bitstreams with no in-band SMC. If the transport format is LATM with or without LOAS, configuration is assumed to be an SMC, for all other file formats an ASC. | |
| aac_fdk::AACDecoderFDK * | driver () |
| void | end () |
| bool | isNotifyActive () |
| Checks if the automatic AudioInfo update is active. | |
| virtual bool | isResultPCM () |
| If true, the decoding result is PCM data. | |
| virtual | 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. | |
| void | setOutput (Print &out_stream) |
| Defines the output stream. | |
| virtual size_t | write (const void *in_ptr, size_t in_size) |
