要解决AWS Medialive和不稳定的HLS流媒体的问题,可以尝试以下方法:
以下是一些示例代码,用于创建AWS Medialive Channel并配置监控:
import boto3
medialive = boto3.client('medialive')
def create_channel():
response = medialive.create_channel(
InputAttachments=[
{
'InputId': 'input-id', # 替换为实际的输入ID
'InputAttachmentName': 'input-attachment-name' # 替换为实际的输入附件名称
},
],
ChannelClass='SINGLE_PIPELINE',
Destinations=[
{
'Id': 'destination-id', # 替换为实际的目标ID
'Settings': [
{
'Url': 'destination-url', # 替换为实际的目标URL
'Username': 'destination-username', # 替换为实际的目标用户名
'PasswordParam': 'destination-password-param', # 替换为实际的目标密码参数
'CertificateArn': 'destination-certificate-arn', # 替换为实际的目标证书ARN
},
]
},
],
EncoderSettings={
'TimecodeConfig': {
'Source': 'SYSTEM_CLOCK' # 使用系统时钟作为时间码源
},
# 其他编码器设置
},
InputSpecification={
'Codec': 'AVC', # 替换为实际的编解码器
'Resolution': 'HD', # 替换为实际的分辨率
},
Name='channel-name', # 替换为实际的频道名称
RoleArn='role-arn', # 替换为实际的角色ARN
)
return response['Channel']['Id']
def create_channel_alarm(channel_id):
cloudwatch = boto3.client('cloudwatch')
response = cloudwatch.put_metric_alarm(
AlarmName='channel-alarm', # 替换为实际的警报名称
AlarmDescription='HLS stream instability', # 替换为实际的警报描述
AlarmActions=[
'sns-topic-arn' # 替换为实际的SNS主题ARN
],
MetricName='BufferFillPercentage', # 替换为实际的指标名称
Namespace='AWS/MediaLive',
Statistic='Average',
Dimensions=[
{
'Name': 'ChannelId',
'Value': channel_id
},
],
Period=60, # 替换为实际的周期
EvaluationPeriods=1,
Threshold=90.0, # 替换为实际的阈值
ComparisonOperator='GreaterThanOrEqualToThreshold',
)
channel_id = create_channel()
create_channel_alarm(channel_id)
以下是一些示例代码,用于创建AWS Elemental MediaPackage Channel并配置重发:
import boto3
mediapackage = boto3.client('mediapackage')
def create_channel():
response = mediapackage.create_channel(
Id='channel-id', # 替换为实际的频道ID
Description='channel-description', # 替换为实际的频道描述
Tags={
'Key': 'Value' # 替换为实际的标签
}
)
return response['Id']
def create_hls_endpoint(channel_id):
