install

apt install libavdevice-dev libavfilter-dev libopus-dev libvpx-dev pkg-config
# ffmpeg >= 3.2
pip install aiortc

example

from aiortc import RTCPeerConnection, RTCSessionDescription
from aiortc import VideoStreamTrack

async def offer(paramse):
 # 解析 offer
 request_offer = RTCSessionDescription(
 sdp=params['sdp'],
 type=params['type'])

 # 创建一个连接class
 pc = RTCPeerConnection()
 pcs.add(pc)

 # 监听数据通道
 @pc.on("datachannel")
 def on_datachannel(channel):

 # 监听接收数据
 @channel.on("message")
 def on_message(message):
 message_recieve = json.loads(message)
 print("message_recieve:{message_recieve}")

 # 监听断开连接
 @pc.on('iceconnectionstatechange')
 async def on_iceconnectionstatechange():
 print(f'ICE connection state is {pc.iceConnectionState}')
 if pc.iceConnectionState == 'failed':
 await pc.close()
 pcs.discard(pc)

 @pc.on('track')

 print('Track %s received' % track.kind)
 if track.kind == 'audio':
 # 接收语音数据
 frame = await audio_track.recv()
 pass
 elif track.kind == 'video':
 local_video = VideoTransformTrack(track)
 pc.addTrack(local_video)

 @track.on('ended')
 async def on_ended():
 print('Track %s ended' % track.kind)

 # 设置 请求端 连接信息： request_offer
 await pc.setRemoteDescription(request_offer)

 # 设置 响应端 连接信息： answer
 answer = await pc.createAnswer()
 await pc.setLocalDescription(answer)
 # 将 响应端 信息返回给 请求端： offer_result
 offer_result = json.dumps({'sdp': pc.localDescription.sdp, 'type': pc.localDescription.type})
