python如何使用Opus编码实现websocket语音通话?
网友回复
要使用Python通过Opus编码实现WebSocket语音通话,可按以下步骤进行:
1. 安装必要的库首先,需要安装用于Opus编码解码、WebSocket通信和音频处理的库。可以使用以下命令进行安装:
pip install pyaudio opuslib websocketspyaudio:用于录制和播放音频。opuslib:用于Opus编码和解码。websockets:用于WebSocket通信。2. 服务端代码示例
import asyncio import websockets import opuslib # 初始化Opus编码器和解码器 encoder = opuslib.Encoder(48000, 1, opuslib.APPLICATION_VOIP) decoder = opuslib.Decoder(48000, 1) connected_clients = set() async def handle_connection(websocket, path): connected_clients.add(websocket) try: async for data in websocket: # 解码接收到的Opus数据 decoded_audio = decoder.decode(data, 960) # 广播给其他客户端 for client in connected_clients: if client != websocket: await client.send(data) except websockets.exceptions.ConnectionClosedOK: pass finally: connected_clients.remove(websocket) start_server = websockets.serve(handle_connection, "localhost", 8765) asyncio.get_ev...
