pullAudioFrame abstract method
Pulls the remote audio data.
Before calling this method, call setExternalAudioSink (enabled : true) to notify the app to enable and set the external audio rendering. After a successful call of this method, the app pulls the decoded and mixed audio data for playback. Call this method after joining a channel. Both this method and onPlaybackAudioFrame callback can be used to get audio data after remote mixing. Note that after calling setExternalAudioSink to enable external audio rendering, the app no longer receives data from the onPlaybackAudioFrame callback. Therefore, you should choose between this method and the onPlaybackAudioFrame callback based on your actual business requirements. The specific distinctions between them are as follows: After calling this method, the app automatically pulls the audio data from the SDK. By setting the audio data parameters, the SDK adjusts the frame buffer to help the app handle latency, effectively avoiding audio playback jitter. The SDK sends the audio data to the app through the onPlaybackAudioFrame callback. Any delay in processing the audio frames may result in audio jitter. This method is only used for retrieving audio data after remote mixing. If you need to get audio data from different audio processing stages such as capture and playback, you can register the corresponding callbacks by calling registerAudioFrameObserver.
framePointers to AudioFrame.
Returns When the method call succeeds, there is no return value; when fails, the AgoraRtcException exception is thrown. You need to catch the exception and handle it accordingly.
