Called on the UI thread to allow configuration of audio stream parameters.
Return true to proceed with audio stream capture, or false to cancel it. All members of |params| can optionally be configured here, but they are also pre-filled with some sensible defaults.
|
pure virtual |
Called on the UI or audio stream thread when an error occurred.
During the stream creation phase this callback will be called on the UI thread while in the capturing phase it will be called on the audio stream thread. The stream will be stopped immediately.

pure virtual |
Called on the audio stream thread when a PCM packet is received for the stream.
|data| is an array representing the raw PCM data as a floating point type, i.e. 4-byte value(s). |frames| is the number of frames in the PCM packet. |pts| is the presentation timestamp (in milliseconds since the Unix Epoch) and represents the time at which the decompressed packet should be presented to the user. Based on |frames| and the |channel_layout| value passed to OnAudioStreamStarted you can calculate the size of the |data| array in bytes.
|
pure virtual |
Called on a browser audio capture thread when the browser starts streaming audio.
OnAudioStreamStopped will always be called after OnAudioStreamStarted; both methods may be called multiple times for the same browser. |params| contains the audio parameters like sample rate and channel layout. |channels| is the number of channels.

pure virtual |
Called on the UI thread when the stream has stopped.
OnAudioSteamStopped will always be called after OnAudioStreamStarted; both methods may be called multiple times for the same stream.
