Method Detail

- (instancetype) initWithSession: (id< GCKRemoteDisplaySession >)  session
format: (AVAudioFormat *)  format 

Creates a new audio input.

The format must be linear PCM.

- (void) enqueueAudioBuffer: (const AudioBufferList *)  abl
frames: (uint32_t)  frames
pts: (const struct AudioTimeStamp *)  pts 

Enqueue an audio buffer for conversion and transmission.

The audio samples are converted synchronously to the owning session's format and enqueued for encoding and transmission. The timestamp must have a valid mHostTime field.

The audio buffer must contain samples matching the converter's input format. If this is not the case, behavior is undefined (the app may crash, audio may be garbled, etc).

- (void) reset

Reset the input.

Flush all internal state and buffers. Should be called before discontinuities in the stream, such before and after inserted ads.

Property Documentation

- (id<GCKRemoteDisplaySession>) session
