Public Member Functions | |
OpusAudioDecoder ()=default | |
Construct a new OpusDecoder object. | |
OpusAudioDecoder (Print &out_stream) | |
Construct a new OpusDecoder object. | |
virtual void | addNotifyAudioChange (AudioInfoSupport &bi) |
Adds target to be notified about audio changes. | |
AudioInfo | audioInfo () override |
provides the actual input AudioInfo | |
virtual AudioInfo | audioInfoOut () |
