要解决AWS Kinesis视频流WebRTC在树莓派上的连接警告和错误,你可以尝试以下解决方法。这些方法包括代码示例。
确保树莓派上的摄像头已正确连接和配置。
安装所需的软件依赖项。在树莓派上打开终端,并运行以下命令:
sudo apt-get update
sudo apt-get install -y libopenjp2-7 libtiff5 libjbig0 libcairo2 libavcodec58 libavformat58 libswscale5 libavdevice58 libavutil56 libswresample3 libavfilter7 libopus0 libvpx5 libsrtp2-1
import sys
import logging
import asyncio
import cv2
import time
import boto3
from awscrt import io, auth, mqtt, http
from awsiot import mqtt_connection_builder
# Set up logging
root = logging.getLogger()
root.setLevel(logging.DEBUG)
handler = logging.StreamHandler(sys.stdout)
handler.setLevel(logging.DEBUG)
formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
handler.setFormatter(formatter)
root.addHandler(handler)
# Set up AWS credentials
session = boto3.Session(profile_name='default')
credentials = session.get_credentials().get_frozen_credentials()
# Set up Kinesis Video Streams client
kvs_client = session.client('kinesisvideo')
# Set up MQTT connection
mqtt_connection = mqtt_connection_builder.mtls_from_path(
endpoint='',
cert_filepath='',
pri_key_filepath='',
client_bootstrap=io.IOEventLoopGroup(),
ca_filepath='',
on_connection_interrupted=on_connection_interrupted,
on_connection_resumed=on_connection_resumed,
client_id='',
clean_session=False,
keep_alive_secs=6
)
# Connect to AWS IoT
connect_future = mqtt_connection.connect()
# Wait for connection to be established
connect_future.result()
# Publish video frames to Kinesis Video Stream
while True:
# Capture frame from camera
ret, frame = cap.read()
# Convert frame to byte array
ret, buffer = cv2.imencode('.jpg', frame)
frame_bytes = buffer.tobytes()
# Publish frame to Kinesis stream
kvs_client.put_media(
StreamName='',
StreamARN='',
FragmentTimecodeType='RELATIVE',
Payload=frame_bytes
)
# Sleep for 1 second
time.sleep(1)
确保您的树莓派具有足够的网络带宽和稳定的网络连接,以支持视频流的传输和接收。
检查树莓派上的防火墙设置,确保允许所需的网络端口通过。
检查树莓派上的摄像头驱动程序是否已正确安装和配置。您可以通过在终端中运行以下命令来检查摄像头是否正常工作:
raspistill -o test.jpg
如果摄像头正常工作,它将拍摄一张照片并将其保存为test.jpg。
希望这些解决方法能帮助您解决树莓派上的连接警告和错误。
