RtcOptions Class

The RtcOptions class represents the configuration options for an RTC (Real-Time Communication) session.

Constructor:

RtcOptions(
    *,
    channel_name: str = None,
    uid: int = 0,
    sample_rate: int = 24000,
    channels: int = 1,
    enable_pcm_dump: bool = False
)

• channel_name: Name of the channel.
• uid: Unique identifier for the user.
• sample_rate: Sample rate for audio (default is 24,000 Hz).
• channels: Number of audio channels (default is 1).
• enable_pcm_dump: Flag to enable PCM audio dump (default is False).

AudioStream Class

The AudioStream class represents an iterable stream of PCM audio frames.

Constructor:

AudioStream()

Methods:

• __aiter__() -> AsyncIterator[PcmAudioFrame]: Async iterator to traverse through audio frames.
• __anext__() -> PcmAudioFrame: Returns the next audio frame in the queue.

---

Channel Class

The Channel class handles the RTC channel and associated operations such as connection, audio subscriptions, and data stream messages.

Constructor:

Channel(rtc: "RtcEngine", options: RtcOptions)

Methods:

• connect() -> None: Connects to the channel asynchronously.
• disconnect() -> None: Disconnects from the channel asynchronously.
• get_audio_frames(uid: int) -> AudioStream: Returns the audio stream for a specific user.
• push_audio_frame(frame: bytes) -> None: Sends a PCM audio frame to the channel.
• clear_sender_audio_buffer() -> None: Clears the audio buffer used for sending.
• subscribe_audio(uid: int) -> None: Subscribes to a user's audio stream.
• unsubscribe_audio(uid: int) -> None: Unsubscribes from a user's audio stream.
• send_stream_message(data: str, msg_id: str) -> None: Sends a data stream message to the channel.

---

ChatMessage Class

Represents a chat message to be sent over the RTC channel.

Constructor:

ChatMessage(message: str, msg_id: str)

---

Chat Class

Handles the queue of chat messages and sends them over the RTC channel.

Constructor:

Chat(channel: Channel)

Methods:

• send_message(item: ChatMessage) -> None: Sends a chat message.

---

RtcEngine Class

The RtcEngine class initializes the Agora service and provides methods for managing RTC channels.

Constructor:

RtcEngine(appid: str, appcert: str)

Methods:

• create_channel(options: RtcOptions) -> Channel: Creates an RTC channel with the given options.
• destroy() -> None: Destroys the RTC engine instance.
